Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a cleaning base station. Background Art

[0002] The floor scrubber is usually used in conjunction with a cleaning base station. After use, the floor scrubber can be returned to the cleaning base station for automatic cleaning, such as hot water cleaning and hot air drying of the roller brush.

[0003] However, the hot water and hot air systems in a cleaning station are often produced by two separate sets of equipment, which not only increases production costs but also takes up a lot of space, limiting the miniaturization of the cleaning station. Furthermore, hot air systems are generally a common feature of cleaning stations, but hot water systems are not. Therefore, if a hot water system needs to be added to a cleaning station that only has a hot air system, there is no space for the hot water system in the original cleaning station, which requires re-molding the cleaning station, increasing costs and resulting in waste. Utility Model Content

[0004] The purpose of this application is to provide a cleaning base station, whose heating module has a composite heating function while not occupying additional space in the base station.

[0005] To achieve the above-mentioned objectives, the present application provides a cleaning base station on one hand, which includes at least a base station body, a heating module and a fan component installed on the base station body. The base station body is provided with a roller brush cleaning groove and a drying air duct connected to the roller brush cleaning groove. The drying air duct extends in the front-to-back direction and is provided with two side walls. The heating module is arranged in the drying air duct. The heating module includes a hot water module for heating liquid, a hot air module for heating gas, and a heating element for heating the hot water module and the hot air module. The hot water module has a hot water flow channel located in the drying air duct and parallel to or perpendicular to the extension direction of the drying air duct.

[0006] It can be seen that the technical solution provided by this application, by installing a heating module with hot air and hot water functions in the drying duct of the cleaning base station, especially the hot water module is set in the drying duct, without occupying space elsewhere in the cleaning base station. It only needs to replace the single-function hot air heating unit in the drying duct of the existing cleaning base station to achieve multi-functional heating, without the need to re-open the mold to free up space for the hot water module, thus reducing production costs. In addition, the compact design of the heating module helps to reduce the overall weight and space occupancy, providing strong support for the lightweight and miniaturization of the cleaning base station.

[0022] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings. Terms such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" used in this application to express spatial relative positions are used to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings for the purpose of ease of explanation. Terms of spatial relative position may be intended to include different orientations of the device in use or work other than the orientation shown in the figures. For example, if the device in the figure is turned over, the unit described as being "below" or "below" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein are interpreted accordingly.

[0023] Furthermore, the terms "installed," "disposed," "provided with," "connected," "slidingly connected," "fixed," and "socketed" should be interpreted broadly. For example, "connected" can mean a fixed connection, a removable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0024] The cleaning station is a crucial auxiliary device for floor scrubbers. By providing automated cleaning and maintenance functions, it significantly improves the convenience and efficiency of floor scrubbers. For example, after use, the scrubber can be returned to the cleaning station to clean its roller brushes. The cleaning station is typically equipped with hot water cleaning and hot air drying functions to ensure thorough cleaning and quick drying of the roller brushes.

[0025] However, the hot water and hot air systems in the cleaning base station are often completed by two independent sets of equipment, and a special placement space is required in the cleaning base station, which not only increases the manufacturing cost, but also adds a large weight and occupies more space, limiting the lightweight and miniaturized design of the cleaning base station, affecting its aesthetics and the user experience. At the same time, if the existing cleaning base station with only a hot air system is to be upgraded to add a hot water function, it is necessary to rearrange the space in the cleaning base station and open a mold to leave room for the hot water system. There is also a prior art method of setting the hot water system in the cleaning equipment, and providing power to the hot water system through the battery in the cleaning equipment. This design not only easily shortens the battery life and service life of the battery in the cleaning equipment, but the power of the hot water system will also be limited by the battery. At the same time, because it is bound to itself, it cannot be used on other cleaning equipment without a hot water system, and its versatility is low.

[0026] To this end, the present application redesigns the hot water system and the hot air system, integrating the hot water heating and hot air heating functions into one module to reduce the volume, weight and cost of the equipment and improve energy utilization. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0027] The present application provides a cleaning base station, which serves as an auxiliary device for cleaning equipment. The cleaning base station may have a cleaning function. When the cleaning equipment is located on the cleaning base station, the cleaning base station can clean and dry the cleaning equipment. In addition, the cleaning base station may also have charging functions, automatic water replenishment functions, automatic sewage discharge functions, and sterilization functions, which are not specifically limited in this application.

[0028] Please also see Figures 1 to 3As shown, in one feasible embodiment, the cleaning base station may include at least a base station body 100, a heating module 200 mounted on the base station body 100, and a fan component 281. The base station body 100 serves as the basic carrier of the cleaning base station and is primarily used to support and protect other components on the cleaning base station. The heating module 200 is used to heat liquid to provide hot water and / or steam, and simultaneously heat the airflow generated by the fan component 281 to provide hot air. The base station body 100 is provided with a cleaning tank 110 and a drying air duct 130 connected to the cleaning tank 110. The drying air duct 130 extends in the front-to-back direction and has two side walls. The heating module 200 is disposed within the drying air duct 130. In the front-to-back direction, the cleaning tank 110 is located in front of the heating module 200. The heating module 200 includes a hot water module for heating liquid, a hot air module for heating gas, and a heating element for providing heat to the hot water module and the hot air module. In other words, the heating module 200 of the present application integrates hot water and hot air functions. By installing the heating module 200 with hot air and hot water functions in the drying air duct 130 of the cleaning base station, the cleaning base station can have both hot water and hot air generation functions. It should be pointed out in particular that the heating module 200 integrated with the hot water module is set in the drying air duct 130, without occupying space elsewhere in the cleaning base station. It only needs to replace the single-function hot air heating unit in the drying air duct 130 of the existing cleaning base station to achieve multi-functional heating. There is no need to re-open the mold to free up the installation space for the hot water module, thereby reducing production costs. In addition, the compact design of the heating module 200 helps to reduce the overall weight and reduce space occupancy, providing strong support for the lightweight and miniaturization of the cleaning base station.

[0029] Specifically, the heating module 200 may include at least a heating tube 210 as a heating element, a liquid tube 220 as a hot water module, and a heat conductor 230, wherein the heat conductor 230 serves as a hot air module. The heating tube 210 converts electrical energy into thermal energy based on the electrothermal effect to provide heat for forming hot water, steam, and hot air. The heating tube 210 has a first end 211, a second end 212, and a first spiral section 213 located between the first end 211 and the second end 212. The first end 211 and the second end 212 are used to connect to a power source so that current can flow into the heating tube 210 for heating. The first spiral section 213 is used to provide more heat exchange area within a limited space by utilizing its own spiral shape, or in other words, to reduce the volume while ensuring the heat exchange area.

[0030] The liquid pipe 220 has a liquid inlet 221, a liquid outlet 222, and a second spiral section 223 located between the liquid inlet 221 and the liquid outlet 222. Liquid enters the liquid pipe 220 through the liquid inlet 221 to be heated, and then flows out of the liquid or steam through the liquid outlet 222. The second spiral section 223 and the first spiral section 213 are alternately wound in the front-to-back direction and maintained at a distance to form a composite spiral structure, thereby increasing the heat exchange time between the liquid in the liquid pipe 220 and the heating pipe 210, reducing the contact distance, and improving the heat exchange efficiency. The liquid pipe 220, which serves as a hot water module, forms a hot water flow channel between the liquid inlet 221 and the liquid outlet 222. The hot water flow channel in the second spiral section 223 extends in the front-to-back direction as a whole, that is, the overall extension direction of the hot water flow channel in the second spiral section 223 is parallel to the drying air duct. The heat conductor 230 has heat-conducting properties. The heat conductor 230 is connected to the heating tube 210 and the liquid tube 220, so that at least part of the heat generated by the heating tube 210 can be transferred to the liquid tube 220 through the heat conductor 230, and used to heat hot water and / or steam, further improving the heat exchange efficiency. At the same time, the heat conductor 230 also plays a connecting role. The heat conductor 230 connects the heating tube 210 and the liquid tube 220 into an integral module, thereby facilitating disassembly and assembly operations. In addition, the heat conductor 230 can also form an air duct extending in the front-to-back direction. The air duct runs through the front and rear ends of the heat conductor 230 in the front-to-back direction. In this way, when the air flow passes through the air duct, the heat transferred to the heat conductor 230 by the heating tube 210 can also heat the air flow passing through the air duct to form hot air.

[0031] That is to say, the present application utilizes a heat conductor 230 to connect the heating tube 210 and the liquid tube 220 to form an integral module, and the heat conductor 230 forms an air duct. In this way, the heating tube 210 can heat the liquid in the liquid tube 220 to form hot water and / or steam through the heat transfer of the heat conductor 230, and can also heat the air flow flowing through the air duct to form hot air, so that a heating module 200 can simultaneously realize the heating of hot water, steam and hot air, or in other words, the hot water heating, steam generation and hot air heating functions are integrated into one module. When the heating module 200 is applied to a cleaning base station, only one heating module 800 can be installed to simultaneously realize the heating of hot water, steam and hot air, simplifying the assembly process, reducing production costs, and also reducing weight and reducing space occupancy, which is conducive to achieving lightweight and miniaturization of the cleaning base station.

[0032] At the same time, it is understood that when the heating tube 210 heats the liquid tube 220 through the heat conductor 230, some of the heat transferred by the heat conductor 230 will diffuse inward and outward. The air duct of the present application utilizes this heat diffused inward and / or outward to heat the airflow to form hot air, thereby fully utilizing the heat generated by the heating tube 210 and improving energy utilization. In addition, the first spiral section 213 of the heating tube 210 and the second spiral section 223 of the liquid tube 220 are alternately wound in the front-to-back direction to form a composite spiral structure, which can increase the contact area between the heating tube 210 and the liquid tube 220 and the heat conductor 230, as well as the overall length of each of the heating tube 210 and the liquid tube 220, thereby improving the heat exchange efficiency between the heating tube 210 and the liquid tube 220 and the heat conductor 230, so that the heating tube 210 can transfer sufficient heat to the heat conductor 230 to heat both the liquid and the airflow.

[0033] In practical applications, the cross-sectional shapes of the heating tube 210 and the liquid tube 220 can be circular, rectangular, or other shapes. The cross-sectional shapes of the heating tube 210 and the liquid tube 220 can be the same or different. The cross-sectional area of ​​the heating tube 210 can be larger than the cross-sectional area of ​​the liquid tube 220 to increase the heat generated by the heating tube 210 and ensure the heating effect. Preferably, the cross-sectional shape of the heating tube 210 and the liquid tube 220 are both circular.

[0034] It should be noted that the heating module 200 of the present application can generate hot air simultaneously with hot water / steam, or can generate at least one of hot water, steam, or hot air independently. In practical applications, given a constant power level in the heating tube 210, the flow rate of liquid entering the liquid tube 220 can be adjusted to determine whether hot water or steam is output. When steam is required, the flow rate is reduced to generate hot steam; when hot water is required, the flow rate is increased to output hot water.

[0035] Regarding the specific structure of the cleaning base station for drying and cleaning the cleaning components of the cleaning equipment (for example, a roller brush, a cleaning cloth or a cleaning disc, etc.), as shown in FIG. Figure 1 As shown, in a feasible embodiment, a first drying port 120 is further provided on the base station body 100, the drying air duct 130 is connected to the first drying port 120, and the opening of the first drying port 120 is arranged toward the cleaning tank 110, so that when the cleaning component is placed in the cleaning tank 110, the hot air flowing through the drying air duct 130 and out through the first drying port 120 can dry the cleaning component.

[0036] The base station body 100 is also provided with a nozzle, which is in communication with the liquid outlet 222 of the liquid pipe 220, or in other words, the nozzle is in communication with the liquid outlet 222 of the hot water flow channel formed by the liquid pipe 220. In this way, at least a portion of the liquid or steam flowing out of the liquid outlet 222 flows into the cleaning tank 110 or is directly sprayed onto the cleaning components through the nozzle, thereby cleaning the cleaning components in the cleaning tank 110 and improving the cleaning effect. The air duct is in communication with the first drying port 120. In this way, the hot air formed by the airflow through the air duct can be at least partially discharged from the first drying port 120, thereby drying the cleaning components, allowing the cleaning components to dry quickly and reducing bacterial growth.

[0037] In this embodiment, the cleaning tank 110 can be an open tank body, which provides a storage location for the cleaning components of the cleaning equipment. In this embodiment, when the cleaning equipment is placed on the cleaning base station, the cleaning components are located in the cleaning tank 110, and the top surface and / or side surfaces of the cleaning equipment do not have a corresponding cleaning base station shell. As an optional embodiment, the cleaning tank 110 can also be surrounded by the base and shell of the base station body 100 (not shown in the figure). When the cleaning components of the cleaning equipment are in the cleaning tank 110, the top surface and side surfaces of the cleaning equipment are opposite to the shell of the base station body 100.

[0038] In practical applications, the air duct can be directly connected to the first drying port 120, or a drainage channel can be provided inside the base station body 100, so that the air duct is connected to the first drying port 120 through the drying air duct, thereby facilitating the installation and arrangement of the heating module 200 within the base station body 100. Similarly, the liquid outlet 222 of the liquid pipe 220 can be directly connected to the nozzle or connected to the nozzle through other pipelines, which is not specifically limited in this application.

[0039] The cleaning base station integrated with the heating module 200 may have at least one of a steam mode, a hot air mode, and a hot water mode.

[0040] In one feasible embodiment, when self-cleaning the cleaning device, the cleaning base station can first be in steam mode. In this case, the liquid pipe 220 can spray steam generated by a small flow of liquid toward the cleaning components to clean them. The high-temperature steam disintegrates and removes stains such as oil on the cleaning components. After the steam mode is completed, the system can switch from steam mode to hot air mode, turning off the water pump supplying water to the liquid pipe 220. The heat from the heating pipe 210 is used to heat the air duct to generate hot air, accelerating the drying of the cleaning components.

[0041] In another optional embodiment, when the cleaning device is self-cleaning, the cleaning base station can first be in hot water mode. At this time, the liquid pipe 220 can pass a large flow of liquid to form hot water in the heating module 200, and the hot water can be injected into the cleaning tank 110, so that the cleaning parts are immersed in hot water for cleaning. In actual application, the cleaning base station can be provided with a nozzle connected to the liquid outlet 222. The nozzle can be directed toward the cleaning parts so that the hot water flowing out of the nozzle is sprayed on the cleaning parts. Of course, the nozzle can also be set toward the cleaning tank 110 so that the hot water is directly injected into the cleaning tank 110.

[0042] In another optional embodiment, the hot water flowing out from the liquid outlet 222 can also flow into the clean water tank of the cleaning equipment through a reversing valve to realize hot water circulation heating, that is, the liquid in the clean water tank of the cleaning equipment is continuously heated and circulated through the heating module on the cleaning base station, so that the liquid in the clean water tank on the cleaning equipment reaches a certain temperature, so as to improve the cleaning effect during self-cleaning and normal cleaning, and improve the user experience.

[0043] Among them, the liquid flowing through the liquid pipe 220 can come from the clean water tank of the cleaning equipment, or the clean water tank on the cleaning base station, or external water supply, etc. At the same time, the liquid in the liquid pipe 220 can be supplied by the above-mentioned multiple water supply sources rather than just a single water supply source.

[0044] When the liquid flowing through the liquid pipe 220 comes from a non-cleaning device, for example, when the liquid flowing through the liquid pipe 220 comes from an external water supply or a clean water tank on a cleaning base station, the cleaning device can first use the liquid in the clean water tank of the cleaning device during steam cleaning or hot water cleaning. When the liquid in the clean water tank of the cleaning device is used up or drops to a certain threshold, the liquid is then replenished into the clean water tank of the cleaning device through the heating module through the clean water tank of the cleaning base station, thereby avoiding hot water directly entering the clean water tank of the cleaning device and mixing with the remaining excess liquid (liquid with relatively low temperature) in the clean water tank of the cleaning device, which causes the temperature of the mixed liquid to be too low, affecting the cleaning effect.

[0045] The spiral lines formed by the first spiral segment 213 and the second spiral segment 223 can be cylindrical spiral lines, conical spiral lines, or a combination of the two. A cylindrical spiral line refers to a curve that spirals around the surface of a cylinder, while a conical spiral line refers to a curve that spirals around a cone.

[0046] Preferably, the spiral line formed by the first and second spiral segments 213, 223 is a cylindrical spiral line. This allows the first and second spiral segments 213, 223 to have a longer length for connection with the heat conductor 230, thereby increasing the contact area between the heating tube 210 and the liquid tube 220 and the heat conductor 230. Furthermore, the interior of the composite spiral structure formed by the first and second spiral segments 213, 223 also has sufficient space to form an air duct.

[0047] In a feasible embodiment, the diameters of the cylinders enclosed by the spiral lines of the first spiral segment 213 and the second spiral segment 223 can be approximately the same, so that the projection of the first spiral segment 213 on the second spiral segment 223 in the front-to-back direction at least partially overlaps with the second spiral segment 223, so that the front and rear sides of the first spiral segment 213 in the front-to-back direction can be wrapped and surrounded by the second spiral segment 223 and the distance is relatively close, thereby improving the heat transfer effect from the first spiral segment 213 to the second spiral segment 223.

[0048] Of course, in another optional embodiment, the diameters of the cylinders enclosed by the spiral lines of the first spiral segment 213 and the second spiral segment 223 may also differ greatly, so that the projection of the first spiral segment 213 on the second spiral segment 223 in the front-to-back direction does not overlap with the second spiral segment 223, thereby presenting a situation where the first spiral segment 213 is located inside the second spiral segment 223, or a situation where the second spiral segment 223 is located inside the first spiral segment 213.

[0049] However, considering that the heat required for heating the liquid in the liquid tube 220 is often large, a high heat transfer effect is required from the first spiral segment 213 to the second spiral segment 223 to ensure that the liquid tube 220 can absorb sufficient heat to make the liquid therein reach a preset temperature. Therefore, the present application preferably adopts a method in which the projection of the first spiral segment 213 on the second spiral segment 223 in the front-to-back direction at least partially overlaps with the second spiral segment 223.

[0050] like Figure 2 As shown, in one feasible embodiment, the air duct may include a first air duct 240, which extends in the front-to-back direction and passes through the interior of the composite spiral structure. The first air duct 240 forms a first air outlet 241 at the rear end of the heat conductor 230 in the front-to-back direction, and a first air inlet 242 at the front end of the heat conductor 230 in the front-to-back direction. Airflow enters the heat conductor 230 through the first air inlet 242, is heated to form hot air, and is then discharged from the first air outlet 241. In this way, the first air duct 240 can use the heat diffused inwardly from the heat conductor 230 to heat the airflow flowing through the first air duct 240 to form hot air.

[0051] At the same time, it can be understood that the projection of the above-mentioned first spiral segment 213 on the second spiral segment 223 in the front-to-back direction at least partially overlaps with the second spiral segment 223, so that the interior of the composite spiral structure formed by the first spiral segment 213 and the second spiral segment 223 has sufficient space to form the above-mentioned first air duct 240.

[0052] Furthermore, the axis of the first air duct 240 roughly coincides with the axis of the composite spiral structure, so that the distance between the inner wall of the first air duct 240 and the heating tube 210 is roughly the same, thereby ensuring that the first air duct 240 heats the air flow flowing therethrough uniformly.

[0053] like Figure 4 As shown, in a feasible embodiment, the above-mentioned heat conductor 230 can be a casting, that is, the heat conductor 230 is cast and connected to the first spiral segment 213 and the second spiral segment 223 through a casting process, and fills the gap between the first spiral segment 213 and the second spiral segment 223, so that the first spiral segment 213 and the second spiral segment 223 can be fully contacted through the heat conductor 230, thereby improving the heat conduction efficiency.

[0054] Furthermore, the heat conducting member 230 can form an inner wall surface 231 and an outer wall surface 232 during the casting process, wherein the inner wall surface 231 surrounds the first air duct 240 , thereby eliminating the need for additional processing of the first air duct 240 , simplifying the production process and reducing production costs.

[0055] In another optional embodiment, the heat conducting member 230 may be connected to the first spiral segment 213 and the second spiral segment 223 by welding or other mechanical connection methods. Alternatively, the heat conducting member 230 may be filled between the first spiral segment 213 and the second spiral segment 223 with a heat conductive adhesive or a heat conductive material in a limited manner to achieve the connection between the first spiral segment 213 and the second spiral segment 223.

[0056] In order to further improve the heating effect of the airflow flowing through the first air duct 240, as Figure 4 As shown, in one feasible embodiment, the inner wall surface 231 is provided with a plurality of first ribs 233 extending inwardly, and the inner wall surface 231 and the plurality of first ribs 233 together enclose and form the first air duct 240. This design can increase the surface area of ​​the first air duct 240, thereby increasing the contact area between the heat conducting member 230 and the airflow flowing through the first air duct 240, thereby improving the heating effect on the airflow flowing through the first air duct 240.

[0057] In practical applications, the first fins 233 can be integrally formed with the heat conducting member 230 during the casting process. The first fins 233 can also be formed separately from the heat conducting member 230 and then connected by welding, bonding, or other methods. The number of first fins 233 can be one or more. When there are multiple first fins 233, the multiple first fins 233 can be arranged in a circular array around the axis of the first air duct 240.

[0058] like Figure 4 and Figure 5 As shown, in one feasible embodiment, the air duct may further include a second air duct 250 located on the periphery of the first air duct 240. Specifically, the heating module 200 further includes a sleeve 260, which is sleeved around the periphery of the heat conductive member 230. The sleeve 260 and the outer wall surface 232 of the heat conductive member 230 together enclose the second air duct 250. In other words, the second air duct 250 is equivalent to being sleeved outside the composite spiral structure, thereby utilizing the heat diffused outward from the heat conductive member 230 to heat the airflow passing through the second air duct 250, thereby improving energy utilization.

[0059] It's worth noting that the air ducts include a first air duct 240 and a second air duct 250, which increases the cross-sectional area of ​​the air ducts, thereby increasing the volume of hot air generated and improving the drying effect on the cleaning components. Furthermore, the first air duct 240 and the second air duct 250 are located on both the inner and outer sides of the heat conductor 230, fully utilizing the heat dissipated inward and outward from the heat conductor 230, reducing heat waste and improving energy efficiency.

[0060] In another optional embodiment, the air duct may also only include the second air duct 250, so that hot air is generated by heating the air flow flowing through the second air duct 250 for drying the cleaning components.

[0061] Furthermore, the outer wall 232 may be provided with a plurality of outwardly extending second fins 234. The sleeve 260, the outer wall 232, and the plurality of second fins 234 collectively enclose and form the second air duct 250. This design increases the contact area between the heat conducting member 230 and the airflow flowing through the second air duct 250, thereby enhancing the heating effect on the airflow flowing through the second air duct 250.

[0062] In practical applications, the second fins 234 can be integrally formed with the heat conducting member 230 during the casting process. The second fins 234 can also be formed separately from the heat conducting member 230 and then connected by welding, bonding, or other methods. The number of second fins 234 can be one or more. When there are multiple second fins 234, the multiple second fins 234 can be spaced apart along the axial direction of the outer wall surface 232.

[0063] In a feasible embodiment, the second rib 234 may extend continuously from the front end of the heat conducting member 230 to the rear end of the heat conducting member 230 .

[0064] Considering that when the second fin 234 is integrally cast with the heat conducting member 230, if the second fin 234 extends continuously from the front end of the heat conducting member 230 to the rear end of the heat conducting member 230, the overall strength of the second fin 234 will be weak, easy to deform, and difficult to demold. Figure 6 As shown, the second ribs 234 may extend from the front end of the heat conducting member 230 to the rear end of the heat conducting member 230 , and there may be interruptions therein to ensure the strength of the second ribs 234 and facilitate the demoulding operation.

[0065] like Figure 2 and Figure 7 As shown, in one achievable embodiment, the heating module 200 may further include a flow guide 280, which is disposed on a fan component 281. The fan component 281 includes a flow guide member 270 at the rear end and a fan at the front end. The flow guide 280 is connected to the sleeve 260.

[0066] The guide member 270 is located at the front end of the heat conducting member 230 along the front-to-back direction. The guide member 270 is arranged roughly coaxially with the first air duct 240. The guide member 270 has a conical gathering portion 271, which is arranged toward the first air duct 240, and the gathering portion 271 partially extends into the first air duct 240. In this way, when the air flow flows through the gathering portion 271 in the front-to-back direction, according to the Coanda effect (when the fluid approaches a curved surface, the velocity of the fluid increases near the surface, resulting in a decrease in pressure, thereby attracting the fluid to flow along the surface), the gathering portion 271 can attract the air flow to flow toward its outer surface, and gather along the outer surface of the gathering portion 271 into the first air duct 240, thereby increasing the air flow rate flowing to the first air duct 240, and at the same time slowing down the air flow rate flowing to the second air duct 250, so as to ensure that the air flow rate flowing through the first air duct 240 and the second air duct 250 is relatively balanced, avoiding the problem of excessive flow causing too low temperature and too small flow causing too high temperature, and ensuring the heating effect of the first air duct 240 and the second air duct 250 on the air flow.

[0067] In practical applications, the outer surface of the gathering portion 271 can be a surface formed by rotating a straight line, or a surface formed by rotating a curved surface, and this application does not make any specific limitation on this.

[0068] Furthermore, the first air inlet 242 may be opened outward in a direction perpendicular to the front-to-back direction to form a “trumpet-mouth” structure, so that the airflow can easily flow into the first air duct 240 through the first air inlet 242 .

[0069] The fan component 281 is mounted within the air duct 280, with the converging portion 271 positioned between the fan component 281 and the heat conductor 230. When hot air is required, the fan component 281 generates a forward-backward airflow. This airflow, constrained by the air duct 280, flows entirely into the air duct, where it is heated and converted into hot air. Thus, the heating module 200 integrates the fan component 281, creating a modular heating system that eliminates the need for a separate fan component 281 installation, simplifying assembly and disassembly.

[0070] In one feasible embodiment, the fan component 281 can be directly connected to the air deflector 280. In another optional embodiment, the flow guide member 270 is connected to the air deflector 280, and the end of the flow guide member 270 away from the gathering portion 271 is provided with a mounting groove 272. The motor of the fan component 281 is installed in the mounting groove 272, thereby being connected to the air deflector 280 through the flow guide member 270.

[0071] like Figure 5 As shown, in a feasible embodiment, the heating module 200 may further include a first temperature detection device 291 and a second temperature detection device 292. The first temperature detection device 291 is located behind the first air duct 240 or the second air duct 250 in the front-to-back direction, and is used to detect the temperature of the hot air flowing out of the first air duct 240 and / or the second air duct 250, so as to determine whether the temperature of the hot air has reached the first preset temperature. The second temperature detection device 292 is located at the liquid outlet 222 or downstream of the liquid outlet 222, so as to detect the temperature of the hot water or steam discharged from the liquid outlet 222, so as to determine whether the temperature of the hot water or steam has reached the second preset temperature. It is worth mentioning that the heating module 200 realizes closed-loop control through a built-in temperature detection device, integrates temperature detection into the heating module 200 itself, and forms a modular heating system, which eliminates the need to additionally install corresponding temperature detection devices, thereby simplifying the disassembly and assembly operations.

[0072] In actual applications, the first temperature detection device 291 and the second temperature detection device 292 serve as detection elements for monitoring the temperature of the hot air and the temperature of the hot water / steam in real time, and comparing them with the corresponding preset temperature values. Based on the comparison results, it is determined whether the heating power of the heating tube 210 needs to be adjusted, so that the heating module 200 can output hot water, steam or hot air at a constant and stable temperature.

[0073] like Figure 5 and Figure 8 As shown, in a feasible embodiment, the heat conductor 230 is provided with an end cover portion 235 at the rear end along the front-to-back direction, and the end cover portion 235 is provided with a second air outlet 251. The end cover portion 235 covers the rear end of the second air duct 250 along the front-to-back direction, and the rear end of the second air duct 250 along the front-to-back direction is connected to the second air outlet 251.

[0074] In practical applications, the end cap 235 can be integrally formed with the heat conducting member 230, and accordingly, the first air outlet 241 is also formed on the end cap 235. Of course, the end cap 235 and the heat conducting member 230 can also be formed separately and then connected to each other. The second air outlet 251 can be a continuous and uninterrupted opening. The second air outlet 251 can also be composed of multiple openings, with each opening communicating with two adjacent second ribs 234.

[0075] In one feasible embodiment, the liquid inlet 221, the liquid outlet 222, the first end 211, and the second end 212 are all located at the end cover 235. In this way, the connection between the heating tube 210 and the liquid tube 220 can be operated at the same end of the heating module 200, which facilitates disassembly and assembly.

[0076] Of course, in some other feasible implementations, the liquid inlet 221 , the liquid outlet 222 , the first end 211 and the second end 212 may also be partially or entirely located on the side of the heating module 200 .

[0077] In one feasible embodiment, a cavity seat portion 236 is provided at the rear end of the end cover portion 235 in the front-to-back direction. The cavity seat portion 236 encloses a wiring cavity 2361 and a liquid outlet cavity 2362 that are not connected to each other. The liquid outlet 222 is connected to the liquid outlet cavity 2362, so that the hot water or steam flowing out of the liquid outlet 222 passes through the liquid outlet cavity 2362 before flowing out. Accordingly, the second temperature detection device 292 can be installed on the cavity seat portion 236 and extend into the liquid outlet cavity 2362 to detect the temperature of the liquid flowing out of the liquid outlet 222, thereby facilitating the installation operation of the second temperature detection device 292. At the same time, the liquid outlet cavity 2362 can also be used to store scale, or in other words, to allow scale to be deposited and formed in the liquid outlet cavity 2362 as much as possible, thereby facilitating cleaning and reducing the formation of scale in the liquid pipe 220 that affects the heating effect. The first end 211 and the second end 212 are located in the wiring cavity 2361 , and the wiring cavity 2361 accommodates the connection point of the first end 211 and the second end 212 to ensure the overall appearance of the heating module 200 is beautiful.

[0078] In practical applications, the cavity seat 236 can be integrally formed with the heat conducting member 230, i.e., the heat conducting member 230 forms the cavity seat 236 together during the casting process. The wiring cavity 2361 and the liquid outlet cavity 2362 have openings, and a closure cover is connected to the cavity seat 236 to cover or seal the openings of the wiring cavity 2361 and the liquid outlet cavity 2362.

[0079] Please see again Figure 6As shown, in a feasible embodiment, the outer wall surface 232 of the heat conducting member 230 is provided with an accommodating groove 2321 , and a thermostat 293 is installed in the accommodating groove 2321 . The thermostat 293 is used to detect the temperature of the heat conducting member 230 .

[0080] In practice, when the temperature reaches or exceeds a set value, the thermostat can cut off the power to the heating tube 210, stopping heating. This prevents the heat conductor 230 from overheating and melting external components. When the temperature of the heat conductor 230 falls below the set value, the thermostat 293 can activate the heating tube 210, causing it to heat the heat conductor 230 and maintain the temperature of the heat conductor 230 within a relatively stable range.

[0081] A fuse 294 may also be installed in the accommodating groove 2321, and the fuse 294 is connected in series with the thermostat 293. When the current exceeds the rated value of the heating wire or the thermostat, the fuse 294 will melt, thereby cutting off the circuit to prevent equipment damage or fire caused by overload.

[0082] Based on the same inventive concept, Figure 2 As shown, the present application also provides a heating module 200. The heating module may include at least a heating tube 210, a liquid tube 220 and a heat conductor 230. The heating tube 210 has a first end 211, a second end 212 and a first spiral section 213 located between the first end 211 and the second end 212. The liquid tube 220 has a liquid inlet 221, a liquid outlet 222 and a second spiral section 223 located between the liquid inlet 221 and the liquid outlet 222. The first spiral section 213 and the second spiral section 223 are alternately wound along the first direction to form a composite spiral structure. The heat conductor 230 is a casting. The heat conductor 230 is coated with the first spiral section 213 and the second spiral section 223 through a casting process and fills the gap between the first spiral section 213 and the second spiral section 223. A first air duct 240 extending along the first direction is formed inside the composite spiral structure. The first air duct 240 runs through the front end and the rear end of the heat conductor 230 along the first direction.

[0083] Furthermore, the heating module 200 further includes a sleeve 260. The sleeve 260 is sleeved on the outer edge of the heat conducting member 230, and the sleeve 260 and the outer edge of the heat conducting member 230 surround and form a second air duct 250 extending along the first direction, and a plurality of ribs are formed on the inner wall of the first air duct 240 and the outer edge of the heat conducting member 230.

[0084] It should be noted that when the heating module 200 is installed in the cleaning base station, the first direction defined in this application is consistent with the forward direction of the front-to-back direction. The specific structures of the heating tube 210, liquid tube 220, heat conducting member 230, first air duct 240, second air duct 250, and sleeve 260 can be referred to the contents described in the above embodiment and will not be repeated here.

[0085] Based on the same inventive concept, the present application also provides a heating module 200. The heating module 200 includes a heating tube 210 and a heat conductor 230. The heating tube 210 has a first end 211, a second end 212, and a first spiral section 213 located between the first end 211 and the second end 212. The heat conductor 230 covers the first spiral section 213, and the heat conductor 230 forms a liquid flow channel and a first air duct 240. The liquid flow channel has a liquid inlet 221, a liquid outlet 222, and a second spiral section 223 located between the liquid inlet 221 and the liquid outlet 222. The second spiral section 223 and the first spiral section 213 are alternately wound along the first direction to form a composite spiral structure. The first air duct 240 is located in the composite spiral structure and extends along the first direction, and the first air duct 240 runs through the front and rear ends of the heat conductor 230 along the first direction.

[0086] It should be pointed out that, compared with the heating module 200 in the above embodiment, the heating module 200 in this solution only changes the liquid pipe 220 into a liquid flow channel formed by the heat conductor 230. The remaining structures can refer to the contents recorded in the above embodiment and will not be repeated here.

[0087] Based on the same inventive concept, the present application also provides a cleaning device, which may be a cleaning robot with cleaning functions such as washing, sweeping, and mopping. The cleaning device can automatically move on a target surface to clean the target surface. Of course, the cleaning device can also be a handheld floor washer with cleaning functions such as washing, sweeping, and mopping. The user uses the handheld cleaning device to push the cleaning device to move on the target surface to clean the target surface, which is not limited here.

[0088] Specifically, such as Figure 9 As shown, the cleaning device is equipped with a heating module 200, which includes a heating tube 210, a liquid tube 220, and a heat conductor 230. The heating tube 210 has a first end 211, a second end 212, and a first spiral section 213 located between the first end 211 and the second end 212. The liquid tube 220 has a liquid inlet 221, a liquid outlet 222, and a second spiral section 223 located between the liquid inlet 221 and the liquid outlet 222. The first spiral section 213 and the second spiral section 223 are alternately wound along a first direction to form a composite spiral structure. The heat conductor 230 has heat conduction properties and is connected to the first spiral section 213 and the second spiral section 223. The heat conductor 230 forms an air duct extending along the first direction, and the air duct runs through the front and rear ends of the heat conductor 230 along the first direction.

[0089] The cleaning device also has a second drying port 310 and an auxiliary cleaning port 320, wherein the second drying port 310 is connected to the air duct so that the hot air flowing out of the air duct can dry the target surface through the second drying port 310. The auxiliary cleaning port 320 is connected to the liquid outlet 222 so that the hot water / steam flowing out of the liquid outlet 222 can be splashed onto the target surface through the auxiliary cleaning port 320. In actual application, along the moving direction of the cleaning device, the auxiliary cleaning port 320 is located in front of the second drying port 310. In this way, as the cleaning device moves, the auxiliary cleaning port 320 can first splash hot water / steam onto the target surface for auxiliary cleaning, and then the second drying port 310 can dry the cleaned target surface to avoid water stains and improve the user experience.

[0090] It should be noted that the specific structure of the heating module 200 can be referred to the contents described in the above embodiment and will not be repeated here.

[0091] Based on the same inventive concept, the present application also provides a cleaning base station, which includes at least a base station body 100, a heating module 200 installed on the base station body 100, and a fan component 281. The base station body 100 is provided with a cleaning tank 110 and a drying air duct 130 connected to the cleaning tank 110. The drying air duct 130 extends in the front-to-back direction and has two side walls. The heating module 200 is disposed within the drying air duct 130 and is located between the two side walls. The heating module 200 includes a hot water module for heating liquid, a hot air module for heating gas, and a heating element 420 for heating the hot water module and the hot air module. The hot water module has a hot water flow channel 411 located within the drying air duct 130 and perpendicular to the extension direction of the drying air duct 130.

[0092] In a feasible embodiment, the hot air module, the heating element 420 and the hot water module are stacked in the drying air duct 130 along the vertical direction.

[0093] Specifically, such as Figures 10 to 14As shown, in one feasible embodiment, the heating module 200 may include an elongated heat-conducting seat 410, a heating element 420, and heat-dissipating fins 430. The heat-conducting seat 410 is a hot water module and has heat-conducting properties. A hot water flow channel 411 is formed inside the heat-conducting seat 410. The hot water flow channel 411 extends between the two side walls of the drying air duct 130 in a transverse direction perpendicular to the front-to-back direction. The heat-conducting seat 410 extends in the transverse direction. The hot water flow channel 411 passes through the opposite ends of the heat-conducting seat 410 and forms a liquid inlet 221 at one end of the heat-conducting seat 410 and a liquid outlet 222 at the other end of the heat-conducting seat 410. A heating element 420 is installed on the top or bottom of the thermal seat 410, and a heat dissipation fin 430 is installed on the side of the heating element 420 away from the thermal seat 410. The heating element 420 can transfer heat through the thermal seat 410 to heat the liquid in the hot water flow channel 411 to form hot water or steam. The heating element 420 can also transfer heat to the heat dissipation fin 430, thereby heating the air flow passing through the heat dissipation fin 430 to form hot air. The heat dissipation fin 430 serves as a hot air module, using the heat of the heating element 420 to heat the air flow in the drying air duct 130.

[0094] Furthermore, two heating elements 420 can be provided, mounted on the top and bottom of the thermal base 410, respectively. Accordingly, two heat sinks 430 can also be provided, connected to the sides of the two heating elements 420 facing away from the thermal base 410. In this way, the two heating elements 420 simultaneously heat the hot water flow channel 411 through the thermal base 410, improving heating efficiency. Furthermore, airflow can be heated by passing through the two heat sinks 430, increasing the amount of hot air generated.

[0095] In one feasible embodiment, the transverse length of the heat-conducting base 410 matches the width of the drying duct 130 located outside the heat-conducting base 410, so that both ends of the heat-conducting base 410 extend to the side walls of the drying duct 130. In this way, when airflow is transmitted through the drying duct 130, it can be ensured that the airflow contacts the heat dissipation fins 430 located at the top and bottom of the heat-conducting base 410 as much as possible, thereby improving the generation of hot air.

[0096] In actual application, the two ends of the thermal conductive seat 410 along the transverse direction can be directly inserted into the two side walls of the drying duct 130, or the two ends of the thermal conductive seat 410 along the transverse direction can also be connected to the corresponding side walls through connecting parts, so that the two ends of the thermal conductive seat 410 along the transverse direction extend to the two side walls of the drying duct 130 respectively.

[0097] In one feasible embodiment, the heat conducting base 410 can be integrally formed. In another optional embodiment, the heat conducting base 410 can also be assembled into a multi-section structure. For example, the heat conducting base 410 includes a middle section and two end caps, the two end caps are respectively connected to the ends of the middle section, and one end cap is formed with a liquid inlet 221 communicating with the interior of the middle section, and the other end cap is formed with a liquid outlet 222 communicating with the interior of the middle section.

[0098] In practical applications, the middle section can be constructed as a square tube structure and formed from aluminum profiles, surrounding the hot water flow channel 411. The heating element 420 can be a ceramic heating plate or other electric heating tube. Two heating elements 420 are mounted on the upper and lower sides, or the front and rear sides, of the middle section, respectively. Two heat dissipation fins 430 are bonded to the two heating elements 420.

[0099] Furthermore, the end cover located at the other end of the liquid outlet 222 is used as a cavity seat 236, and a liquid outlet cavity 2362 is formed in the cavity seat 236. The hot water flowing out of the hot water flow channel 411 can first enter the liquid outlet cavity 2362, and then flow out from the liquid outlet 222, so that the scale is stored in the liquid outlet cavity 2362, or in other words, the scale is deposited and formed in the liquid outlet cavity 2362 as much as possible, thereby facilitating cleaning and reducing the formation of scale in the hot water flow channel 411 to affect the heating effect.

[0100] Furthermore, a temperature controller 293 is installed on the outer side of the heat-conducting seat 410 , and the temperature controller 293 is used to detect the temperature of the heat-conducting member 230 .

[0101] In practice, when the temperature reaches or exceeds a set value, the thermostat can cut off the power to the heating element 420, stopping heating. This prevents the heating element 420 from overheating and melting external components. When the temperature of the heating element 420 falls below the set value, the thermostat 293 can activate the heating element 420 to heat the thermal base 410, maintaining the temperature of the thermal base 410 within a relatively stable range.

[0102] A fuse 294 may also be installed on the outside of the heat conducting base 410, and the fuse 294 is connected in series with the thermostat 293. When the current exceeds the rated value of the heating wire or the thermostat, the fuse 294 will melt, thereby cutting off the circuit to prevent equipment damage or fire caused by overload.

[0103] like Figure 13 and Figure 14As shown, the cleaning base station is provided with a first drying port 120 for drying the cleaning components, and the drying air duct 130 is connected to the first drying port 120. In this way, the hot air formed by the air flow heated by the heating module 200 located in the drying air duct 130 can be at least partially discharged from the first drying port 120, thereby drying the cleaning components, allowing the cleaning components to dry quickly and reduce bacterial growth. The cleaning tank 110 is connected to the liquid outlet 222. In this way, at least part of the liquid or steam flowing out of the liquid outlet 222 flows into the cleaning tank 110, or is directly sprayed onto the cleaning components placed in the cleaning tank 110, so as to clean the cleaning components in the cleaning tank 110 and improve the cleaning effect.

[0104] The heating module 200 is disposed in the drying air duct 130 and is located in front of the fan component 281. The fan component 281 faces the heating module 200 in the front-to-back direction.

[0105] The heating module 200 includes a long, horizontally extending thermal base 410. Two heating elements 420 are located at the top and bottom of the base 410, respectively. The first heating element is located at the top of the base 410, and the second heating element is located at the bottom of the base 410. A hot water flow channel 411 is provided in the base 410, and the heating elements 420 transfer heat from the base 410 to heat the liquid within the channel. A water pump located within the cleaning base regulates the flow of liquid within the hot water flow channel, allowing the heating module to generate hot water, steam, or both.

[0106] The two heating elements 420 can be directly attached to the outer surface of the heat-conducting seat 410 to heat the heat-conducting seat 410 , or a heat-conducting medium can be provided between the heating elements 420 and the heat-conducting seat 410 to heat the heat-conducting seat.

[0107] The two heat dissipation fins 430 are respectively connected to the first and second heating elements on one side away from the heat conducting seat 410 . The heat dissipation fin connected to the first heating element is defined as the first heat dissipation fin, and the heat dissipation fin connected to the second heating element is defined as the second heat dissipation fin.

[0108] The cleaning base station is also equipped with a water pump (not shown) connected to the liquid inlet of the hot water flow channel 411. The water pump can adjust the flow rate of the liquid delivered to the hot water flow channel 411. Under the same heating power of the heating element 420, when the water pump is in the first flow mode, the hot water flow channel 411 can simultaneously produce hot water and steam. When the water pump is in the second flow mode, the hot water channel only produces hot water. When the water pump is in the third flow mode, the hot water channel 411 only produces steam. The three flow modes of the water pump described above have different liquid flow rates. The second flow mode has the fastest liquid flow rate, the first flow mode has the second fastest liquid flow rate, and the third flow mode has the slowest liquid flow rate.

[0109] The base station is provided with a nozzle connected to the liquid flow channel in the cleaning tank area. The nozzle can spray both steam and hot water, and the nozzle sprays toward the cleaning components such as the roller brush placed in the roller brush cleaning tank.

[0110] By placing the hot water module of the heating module 200 within the drying duct 130, it eliminates the need to occupy additional space within the cleaning base station, improving the utilization of the cleaning base station's molds and ensuring a lightweight and compact design. Furthermore, the heating module 200 installed within the cleaning base station can be heated directly from the mains electricity supply, providing greater heating power than battery-powered systems. The cleaning base station has independent steam, hot water, and hot air functions, making it a universal accessory compatible with various cleaning equipment models.

[0111] The following is a detailed description of a specific application scenario, taking the cleaning equipment as a floor scrubber and the heating module applied to a cleaning base station as an example.

[0112] Application Scenario 1

[0113] A user purchased a floor scrubber that also comes with a cleaning base station. Unlike any previous base stations, this one features a heating module. This module tightly connects the liquid pipe and the heating pipe via a heat conductor, rapidly heating the water flowing through the pipe to the appropriate temperature or forming steam. Simultaneously, the heat conductor cleverly forms an air duct, heating the water and providing the heat energy to generate hot air. This allows a single heating module to generate hot water, steam, and hot air.

[0114] When the user finishes using the floor scrubber and places the floor scrubber on the cleaning base station, the roller brush of the floor scrubber is located in the cleaning tank, and the cleaning base station can cooperate with the floor scrubber to perform self-cleaning operations.

[0115] Specifically, the cleaning base station activates the heating module and enters steam mode. The water pump controls the flow rate into the liquid pipe, causing the liquid pipe to generate steam that sprays cleaning fluid toward the roller brush. The high-temperature steam dissolves oil and other stains on the roller brush. After the steam mode is completed, it switches from steam mode to hot air mode, shutting off the water pump supplying water to the liquid pipe. The heat from the heating pipe is used to heat the air duct, generating hot air, which accelerates the drying of the roller brush, thereby avoiding corrosion and bacterial growth that may be caused by a humid environment and improving the user experience.

[0116] In addition, by generating hot water, steam and hot air through a heating module, the cleaning base station is effectively made smaller and lighter, realizing the lightweight and miniaturization of the cleaning base station, so that the cleaning base station can be flexibly deployed in any corner of the home without occupying valuable living space.

[0117] Application Scenario 2

[0118] The user purchased a floor scrubber, which also comes with a cleaning base station. A heating module is installed inside the drying air duct of this cleaning base station. The heating module integrates a heat-conducting seat with a hot water flow channel and heat dissipation fins on both sides of the heating element and tightly combines them, thereby achieving heat transfer at the same time. That is, it can quickly heat the clean water in the hot water flow channel to the appropriate temperature to form steam or hot water. At the same time, the heat dissipation fins heat the air flow through the air duct to form hot air. Not only does it heat the water, but it also provides thermal energy for the air flow through the air duct, allowing a heating module to selectively generate hot water, steam, and hot air.

[0119] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
