Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning device. Background Technology

[0002] Currently, cleaning equipment such as robot vacuums and floor scrubbers can efficiently clean surfaces (such as floors and countertops). However, they are not effective at removing stubborn stains, requiring multiple cleaning sessions or even manual cleaning, resulting in less than ideal cleaning results and a poor user experience. Utility Model Content

[0003] The main objective of this application is to provide a cleaning device that solves the problem that cleaning devices in the prior art are unable to effectively remove stubborn stains.

[0015] Furthermore, the cleaning equipment also includes:

[0016] A central sweeping assembly is installed at the bottom of the device body, and the steam injection component is located between the central sweeping assembly and the roller component.

[0017] Furthermore, along the forward direction of the cleaning equipment, there is a first distance between the steam injection component and the roller component, and a second distance between the steam injection component and the intermediate sweeping assembly, wherein the first distance is less than the second distance.

[0018] Furthermore, the bottom of the device body is provided with an installation cavity and a receiving cavity. The middle sweeping component is installed in the installation cavity, and the roller component is installed in the receiving cavity. Along the forward direction of the cleaning device, the distance between the side of the receiving cavity near the first spray hole and the side of the first spray hole away from the receiving cavity is D1, and the distance between the side of the installation cavity near the first spray hole and the side of the first spray hole near the installation cavity is D2. D1 and D2 satisfy the relationship: 0.15≤D1÷D2≤0.35.

[0019] Furthermore, the self-cleaning component includes:

[0021] A squeegee is attached to the side of the mounting plate away from the steam jet component and abuts against the roller component along the forward direction of the cleaning equipment.

[0022] Furthermore, the cleaning assembly also includes a clean water tank and a first water pump, the clean water tank being installed within the device body, the first water pump being connected between the clean water tank and the water supply channel, and the steam supply component including:

[0023] A steam generator is installed on the side of the equipment body near the connecting pipe. The steam generator includes an output port and an input port, and the output port is connected to the connecting pipe.

[0024] The second water pump is installed inside the device body and is connected between the clean water tank and the inlet.

[0025] Furthermore, it also includes:

[0026] A three-way connector is installed inside the equipment body. The three-way connector includes a first interface, a second interface, and a third interface. The first interface is connected to the clean water tank, the second interface is connected to the first water pump, and the third interface is connected to the second water pump.

[0029] Furthermore, along the first direction, a first groove is provided between the bottom surface of the channel and the first nozzle, and the cross-section of the first groove along the axial direction of the first nozzle gradually decreases towards the direction of the first nozzle.

[0030] In this application, the cleaning component of the cleaning equipment is installed at the bottom of its main body. The cleaning component includes a roller assembly and a self-cleaning component. The roller assembly is used for wet cleaning of the surface to be cleaned, and the self-cleaning component is located on one side of the roller assembly to clean it, ensuring that the roller assembly is always kept clean while cleaning the surface. To improve the ability to remove stubborn stains, the cleaning equipment also includes a steam assembly, which includes a steam supply component and a steam injection component. The steam supply component is installed in the main body and communicates with the steam injection component. Along the forward direction of the cleaning equipment, the steam injection component is located at the front of the cleaning component. The steam supply component generates steam and delivers it to the steam injection component. Therefore, during the process of the cleaning equipment moving forward to drive the roller component to clean the surface to be cleaned, steam is first sprayed onto the surface through the steam jet component. Stubborn stains on the surface are softened, melted, and / or loosened by the steam. When the roller component passes over these stubborn stains, they are easily cleaned. Furthermore, because the roller component has already been cleaned by the self-cleaning component before passing over the stubborn stains, no other stains are left on the surface, improving the cleaning effect. At the same time, since the self-cleaning component is located between the steam jet component and the top of the equipment body, the space utilization of the equipment body is improved, increasing the overall compactness of the cleaning equipment structure. Moreover, because the steam jet component is located at the bottom of the equipment body, close to the surface to be cleaned, the spray force of the steam jet component applied to the stubborn stains is increased, as is the amount of steam in contact with the stubborn stains, thus ensuring that the stubborn stains are fully softened and dissolved.

[0047] To address the problem that existing cleaning equipment struggles to effectively remove stubborn stains, the first embodiment of this invention provides a cleaning device. Please refer to [link / reference]. Figures 1 to 9 The cleaning equipment includes a main body 10, a cleaning component 20, and a steam component 30.

[0048] The cleaning assembly 20 is installed at the bottom of the device body 10. The cleaning assembly 20 includes a roller component 21 and a self-cleaning component 22. The self-cleaning component 22 is disposed on one side of the roller component 21 to clean the roller component 21, ensuring that the roller component 21 is always in a relatively clean state when cleaning the surface to be cleaned. A receiving cavity 11 may be provided at the bottom of the device body 10. The receiving cavity 11 has an opening facing the surface to be cleaned. The cleaning assembly 20 is installed within the receiving cavity 11 to ensure that the roller component 21 can clean the surface to be cleaned.

[0049] Steam assembly 30 includes a steam supply component 31 and a steam injection component 32. The steam supply component 31 is installed on the equipment body 10 and communicates with the steam injection component 32 along the forward direction of the cleaning equipment (e.g., ...). Figure 1 (In the direction indicated by the middle arrow X), the steam injection component 32 is located in front of the cleaning assembly 20, so that the steam injection component 32 passes over stubborn stains on the path before the roller component 21. Along the first direction (e.g. Figure 1 The self-cleaning component 22 is located between the steam injection component 32 and the top of the device body 10 (in the direction indicated by the middle arrow Y, where the first direction is the height direction of the device body). This allows for full utilization of the installation space within the device body 10 and improves the overall compactness of the cleaning equipment structure. The steam supply component 31 generates steam and delivers it to the steam injection component 32, which then sprays steam in a direction away from the top of the device body 10.

[0050] The steam emitted by the steam jet component 32 has a certain amount of heat. When this steam is sprayed onto stubborn stains, it softens, melts, and loosens them, making it easier for the roller component 21 to clean them. This eliminates the need for multiple cleaning sessions or even manual cleaning, saving energy and effort and providing a better user experience. Simultaneously, the roller component 21 is first cleaned by the self-cleaning component 22 before proceeding to clean the stubborn stains, further improving the cleaning effect on areas with stubborn stains and preventing other stains from remaining.

[0051] As can be seen, in this embodiment, the cleaning component 20 of the cleaning equipment is installed at the bottom of its main body 10. The cleaning component 20 includes a roller component 21 and a self-cleaning component 22. The roller component 21 is used for wet cleaning of the surface to be cleaned, and the self-cleaning component 22 is disposed on one side of the roller component 21 to clean the roller component 21, so that the roller component 21 is always kept clean while cleaning the surface to be cleaned. To improve the ability to clean stubborn stains, the cleaning equipment also includes a steam component 30. The steam component 30 includes a steam supply component 31 and a steam injection component 32. The steam supply component 31 is installed on the main body 10 and communicates with the steam injection component 32. Along the forward direction of the cleaning equipment, the steam injection component 32 is located at the front of the cleaning component 20. The steam supply component 31 is used to generate steam and deliver the steam to the steam injection component 32. Therefore, during the process of the cleaning equipment moving forward to drive the roller component 21 to clean the surface to be cleaned, steam is first sprayed onto the surface to be cleaned through the steam injection component 32. Stubborn stains on the surface are softened, melted, and / or loosened under the action of the steam. When the roller component 21 passes over the stubborn stains, the stains can be easily cleaned. Furthermore, since the roller component 21 has been cleaned by the self-cleaning component 22 before passing over the stubborn stains, the stubborn stains are cleaned without leaving any other stains on the surface to be cleaned, improving the cleaning effect. At the same time, since the self-cleaning component 22 is located between the steam injection component 32 and the top of the equipment body 10, the space utilization of the equipment body 10 is improved, increasing the compactness of the overall structure of the cleaning equipment. Moreover, since the steam injection component 32 is located at the bottom of the equipment body 10, close to the surface to be cleaned, the spray force of the steam injected by the steam injection component 32 on the stubborn stains is increased, as is the amount of steam in contact with the stubborn stains, thereby ensuring that the stubborn stains are fully softened and dissolved.

[0052] The roller assembly 21 includes a drive unit, a roller, and a mop. The roller is connected to the drive unit and can rotate around its own axis under the drive of the drive unit. The mop is laid on the outer circumference of the roller so that it can roll under the drive of the roller to achieve efficient cleaning of the surface to be cleaned.

[0053] Please see Figure 2 as well as Figures 4 to 7In this embodiment, the steam injection component 32 includes a main body 321 and a connecting pipe 322. The main body 321 extends along the axial direction of the roller component 21 (i.e., the axial direction of the roller). A channel 210 and multiple first spray holes 213 are provided within the main body 321. Along the axial direction of the roller component 21, multiple first spray holes 213 are sequentially arranged at the bottom of the main body 321 away from the self-cleaning component 22 and are respectively connected to the channel 210. The connecting pipe 322 is located at one end of the main body 321 along its length and is connected to the channel 210; the end of the connecting pipe 322 away from the channel 210 is connected to the steam supply component 31. After the steam supply component 31 generates hot steam, the connecting pipe 322 transmits the steam to the channel 210 and sprays it onto the surface to be cleaned through the first spray holes 213. The main body 321 has a length extending along the axial direction of the roller component. Since the multiple first nozzles 213 are arranged along the axial direction of the roller component (the multiple first nozzles 213 can be spaced apart or arranged adjacently), the coverage area of ​​stubborn stains on the surface to be cleaned can be increased. This ensures that stubborn stains located along the roller travel path in each area along the axial direction of the roller component can be sprayed with steam. Therefore, when the roller component 21 passes by, it ensures that all stubborn stains on the surface to be cleaned that come into contact with the roller component 21 can be thoroughly cleaned. Specifically, along the first direction (i.e., the height direction of the equipment body 10), Figure 1 (In the direction indicated by the middle arrow Y), a first groove 215 is provided between the bottom surface of channel 210 and the first nozzle 213. The cross-section of the first groove along the axial direction of the first nozzle 213 gradually decreases towards the first nozzle 213. The first groove 215 can accumulate steam, which can increase the steam pressure of the first nozzle 213. The higher the steam pressure, the stronger the force of the steam on stubborn stains, which is conducive to more thorough stain removal and improved cleanliness. The steam accumulation before spraying can also increase the coverage area of ​​the sprayed steam on stubborn stains. It can also increase the flow rate of the steam when it is sprayed, thereby increasing the impact force of the steam on stubborn stains, making it easier for stubborn stains to soften, dissolve and loosen.

[0054] like Figure 5As shown, the channel 210 within the main body 321 includes a first channel segment 211 and a second channel segment 212. The first channel segment 211 extends along the length of the main body 321 and is located on the side of the main body 321 near the connecting pipe 322. The first channel segment 211 includes a first flow channel 111 and a second flow channel 112. Along the forward direction of the cleaning device, the first flow channel 111 is located on the side of the second flow channel 112 away from the roller and communicates with the connecting pipe 322. At least two first nozzles 213 are located at the bottom of the second flow channel 112 and communicate with the second flow channel 112. The number of first nozzles 213 provided at the bottom of the second flow channel 112 may include one of two, three, four, five, or other numbers greater than two. The second channel segment 212 extends along the length of the main body 321 and is located on the side of the first channel segment 211 away from the connecting pipe 322. The second channel segment 212 includes a third flow channel 121 and a fourth flow channel 122. The third flow channel 121 is disposed opposite to the second flow channel 112 and communicates with the first flow channel 111. At least two other first nozzles 213 are located at the bottom of the third flow channel 121 and communicate with it. Similarly, the number of first nozzles 213 disposed at the bottom of the third flow channel 121 may include one of two, three, four, five, or more than two. The fourth flow channel 122 is disposed opposite to the first flow channel 111 and is isolated from the first flow channel 111. After the connecting pipe 322 transmits steam to the first flow channel 111, the steam enters the second flow channel 112 and the third flow channel 121 respectively. Since the width of the second flow channel 112 and the third flow channel 121 is smaller than the width of the entire channel 210, the second flow channel 112 and the third flow channel 121 are narrow flow channels. During the process of steam entering the narrow flow channels, the steam pressure entering the second flow channel 112 and the third flow channel 121 will increase while the steam volume remains unchanged. Under the greater steam pressure, the stubborn stains will also be subjected to greater steam pressure when the first nozzle 213 sprays steam onto the surface to be cleaned. This makes it easier for the stubborn stains to be softened, dissolved, and loosened under the action of steam. When the roller component 21 passes over the stubborn stains, the stubborn stains will be more easily cleaned by the roller component 21, thus improving the cleaning effect of the roller component 21 on stubborn stains.

[0055] The first position is the connection point between the first flow channel 111, the second flow channel 112, and the third flow channel 121. Along the axial direction of the roller component 21, the first position is located in the middle of the channel 210. Therefore, when a certain amount of steam flows along the first flow channel 111 to the first position, it ensures that the steam is evenly distributed to the second flow channel 112 and the third flow channel 121, improving the uniformity of steam in various parts of the second and third flow channels 112 and preventing the flow channel near the connecting pipe 322 from having less steam than the flow channel farther from the connecting pipe 322. Consequently, the amount of steam ejected from the multiple first nozzles 213 is basically consistent, allowing each stubborn stain and / or larger stubborn stain on the surface to be cleaned, corresponding to the main body 321, to come into contact with a greater amount of steam.

[0056] like Figure 5 As shown, a first protrusion 101 and a second protrusion 102 are provided within the channel 210. The first protrusion 101 is located in the first channel segment 211 and divides the first channel segment 211 into a first flow channel 111 and a second flow channel 112. The second protrusion 102 is located in the second channel segment 212 and divides the second channel segment 212 into a third flow channel 121 and a fourth flow channel 122. A protrusion 103 is also provided within the channel 210. The protrusion 103 is located on the side wall of the channel 210 near the roller and is located at a first position. There is an installation gap between the protrusion 103 and both the first protrusion 101 and the second protrusion 102. This installation gap connects the first flow channel 111 and the second flow channel 112, as well as the first flow channel 111 and the third flow channel 121. The protrusion 103 can divert the steam entering the second flow channel 112 and the third flow channel 121 from the first flow channel 111. The steam coming from the first flow channel 111 can be fed into the second flow channel 112 and the third flow channel 121 along the corresponding installation gap, ensuring that the steam will not flow into the third flow channel 121 in large quantities due to the action of motion inertia, thereby further improving the uniformity of the amount of steam in the second flow channel 112 and the third flow channel 121.

[0057] The first flow channel 111 has a width along the radial direction of the roller, such as Figure 6 As shown, along the axial direction of the roller component 21, the width of the first flow channel 111 near the connecting pipe 322 is greater than the width away from the connecting pipe 322. This ensures that the first flow channel 111 can accommodate a larger amount of steam from the connecting pipe 322, which is then guided through the first flow channel 111 to the second flow channel 112 and the third flow channel 121. Furthermore, when a larger amount of steam accumulates on the side of the first flow channel 111 near the connecting pipe 322, the pressure on the steam near the second and third flow channels 112 and 121 increases, thereby accelerating the steam flow into the second and third flow channels 112 and 121.

[0058] The axial direction of the first nozzle 213 is parallel to the first direction, that is, the first nozzle 213 is disposed through the main body 321, which is simple and convenient to process.

[0059] The first nozzle 213 has a first width, the maximum value of which is not less than 0.6 mm and not more than 1.5 mm. When the first nozzle 213 is a circular orifice, the first width is the diameter of the first nozzle 213. When the maximum value of the first width is within the above range, it ensures that the first nozzle 213 can eject a large amount of steam without causing the steam flow rate to be too low due to an excessively large diameter at the bottom of the first nozzle 213. The maximum value of the first width (e.g.) Figure 6 The dimension indicated by 'd' may include one of the following: 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, 0.85mm, 0.9mm, 0.95mm, 1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, or other values ​​between 0.6mm and 1mm. The maximum value of the first width is preferably 0.8mm, at which the steam ejected from the first nozzle 213 can fully soften and dissolve stubborn stains.

[0060] Along the forward direction of the cleaning equipment, the axis of the first nozzle 213 is inclined away from the front of the cleaning component 20. Therefore, as the cleaning equipment moves forward, the steam emitted from the first nozzle 213 is sprayed forward at an angle away from the cleaning component 20 onto the stubborn stains. In other words, the first nozzle 213 can spray steam onto the stubborn stains before the cleaning equipment reaches them, allowing the stains to soften and loosen upon contact with the steam, making them easier for the roller component 21 to clean. Furthermore, the time interval between the contact time between the stubborn stains and the steam and the time the roller component 21 reaches the stubborn stains will not cause some stains to re-condense.

[0061] like Figure 10 As shown ( Figure 10 The main body 321 contains only one channel 210 communicating with the first nozzle 213. The channel 210 can also be a structure with multiple flow channels (this embodiment does not impose a unique limitation on the specific structure of the channel 210). The angle between the axis of the first nozzle 213 and the first direction is not less than 10° and not greater than 30°. Therefore, during the process of the first nozzle 213 spraying steam at an angle away from the cleaning component 20 onto stubborn stains, it is ensured that the amount of steam contacting the stubborn stains is sufficient, and that the stubborn stains are not prevented from being sprayed prematurely due to an excessively large or small angle of inclination of the nozzle 102's axis. The angle between the axis of the first nozzle 213 and the first direction (e.g., the angle between the axis of the first nozzle 213 and the first direction) is... Figure 10The included angle α shown may include one of the following: 10°, 10.5°, 11°, 12°, 13°, 14°, 15°, 15.3°, 15.6°, 16°, 17°, 18°, 19°, 20°, 21°, 21.4°, 22°, 23°, 24°, 25°, 25.3°, 25.7°, 26°, 27°, 28°, 29°, 30°, or any other angle value between 10° and 30°.

[0062] With the included angle α of the first nozzle 213 not less than 10° and not greater than 30°, the following verification tests were conducted in this embodiment to verify the steam injection effect of the first nozzle 213:

[0063] 21) When 0 ≤ α < 10°, the dimensions of the wetted area formed on the surface to be cleaned by the steam sprayed from the first nozzle 213 are: ① 22.5 * 31.5; ② 22 * ​​32; ③ 22 * ​​31. Disadvantage: The first nozzle 213 can only spray onto the stain when it reaches directly above it, leaving insufficient time for the stain to completely dissolve, making stubborn stains difficult to clean. Dimensions are measured in millimeters.

[0064] 22) When 10°≤α≤30°, the dimensions of the wetted area formed by the steam sprayed from the first nozzle 213 onto the surface to be cleaned are: ①23*36; ②22.5*35.5; ③24*36. Advantages: The steam sprayed from the first nozzle 213 covers a larger area on the surface to be cleaned. The first nozzle 213 can spray steam onto the stains ahead of time, allowing sufficient time for the stains to dissolve, thus facilitating the cleaning of stubborn stains.

[0065] 23) When α > 30°, the dimensions of the wetted area formed on the surface to be cleaned by the steam sprayed from the first nozzle 213 are: ① 15*31; ② 14.5*30.5; ③ 14.5*31.5. Disadvantages: The angle of the first nozzle 213 is too large, and some of the steam will be sprayed towards the base plate 13 and the middle sweeping component 50 of the cleaning equipment, resulting in a large amount of steam loss and insufficient steam sprayed onto the stains, which is not conducive to the roller component 21 cleaning the stains. Secondly, the distance between the steam sprayed onto the ground and the roller component 21 is too far and narrow, and the stains will solidify after dissolving for too long, which is also not conducive to the roller component 21 cleaning the stains.

[0066] As can be seen from the above measurements, the size of the wetted area is larger when 10°≤α≤30° than when 0≤α<10° and α>30°, allowing sufficient time for the stains to dissolve and facilitating the cleaning of the roller component 21 of the cleaning equipment 00.

[0067] The main body 321 includes a first outer shell 3211 and a second outer shell 3212. Along a first direction, a channel 210 is disposed on the side of the first outer shell 3211 near the self-cleaning component 22, and a connecting tube 322 is located at one end of the first outer shell 3211 along its length. The second outer shell 3212 is detachably fastened to the first outer shell 3211 via a plug-in structure 40 and covers the channel 210. Thus, after machining a groove forming the channel 210 on the first outer shell 3211, the second outer shell 3212 can be fastened together with the first outer shell 3211, making assembly efficient and convenient. The detachability of the first and second outer shells 3211 also facilitates disassembling the main body 321 for maintenance and cleaning of the channel 210 and the first spray nozzle 213.

[0068] like Figure 5 and Figure 7 As shown, the insertion structure 40 includes an annular flange 41 and an annular groove 42. The annular flange 41 is disposed on the side of the first housing 3211 near the second housing 3212 and surrounds the outer periphery of the channel 210. The annular groove 42 is disposed on the side of the second housing 3212 near the first housing 3211 and corresponds to the annular flange 41. The annular flange 41 is adapted to the annular groove 42 and is inserted into the annular groove 42. Thus, not only are the first housing 3211 and the second housing 3212 inserted together, but the fit between the annular flange 41 and the annular groove 42 also seals the channel 210, preventing steam leakage.

[0069] like Figure 1 As shown, the cleaning equipment in this embodiment also includes a central sweeping assembly 50, which is installed at the bottom of the equipment body 10. A steam injection component 32 is located between the central sweeping assembly 50 and the roller component 21. The central sweeping assembly 50 typically includes a roller brush 51, a drive mechanism, and a cover structure 52 for mounting the roller brush 51 onto the equipment body 10. The roller brush 51 can rotate under the drive mechanism to sweep away debris on the surface to be cleaned during rotation. The cleaning equipment is equipped with a dust box for collecting the debris swept up by the roller brush 51.

[0070] In this embodiment, the steam jet component 32 is installed between the intermediate sweeping assembly 50 and the roller assembly 21. This fully utilizes the installation gap between the intermediate sweeping assembly 50 and the roller assembly 21, improving the space utilization rate of the cleaning equipment. Furthermore, it ensures that after the steam jet component 32 sprays steam onto stubborn stains, the roller assembly 21 can promptly clean those stains. This is because if the steam jet component 32 is positioned on the side of the intermediate sweeping assembly 50 away from the roller assembly 21, the roller assembly 21 would only reach the stubborn stains after the steam jet component 32 has sprayed steam onto them for a period of time. By this time, the stubborn stains might have condensed and become even more stubborn under the influence of cold air, affecting the cleaning effect of the roller assembly 21 on the stubborn stains.

[0071] Along the forward direction of the cleaning equipment, there is a first distance between the steam injection component 32 and the roller component 21, and a second distance between the steam injection component 32 and the intermediate sweeping assembly 50. The first distance is smaller than the second distance, meaning that the steam injection component 32 is closer to the roller component 21 than to the intermediate sweeping assembly 50. This further ensures that after the steam injection component 32 sprays steam onto stubborn stains, the roller component 21 can promptly clean the stubborn stains. Secondly, since the dust box collects the debris swept by the intermediate sweeping assembly 50 under vacuum conditions, and the rotational motion of the roller brush 51 disturbs the airflow near the intermediate sweeping assembly 50, if the steam injection component 32 is very close to the intermediate sweeping assembly 50, this airflow can easily weaken the force of the steam sprayed onto the stubborn stains, or even change the direction of the steam spray, reducing the amount of steam sprayed onto the stubborn stains. Therefore, in this embodiment, the steam injection component 32 is positioned closer to the roller component 21 to avoid the aforementioned adverse effects caused by the intermediate sweeping assembly 50.

[0072] In this embodiment, the bottom of the device body 10 is provided with a mounting cavity 14 and a receiving cavity 11. The intermediate sweeping assembly 50 is installed in the mounting cavity 14. Specifically, the roller brush 51 of the intermediate sweeping assembly 50 is installed in the mounting cavity 14 through a cover plate structure 52. The mounting cavity 14 communicates with the dust box to allow the dust box to collect waste. The roller component 21 is installed in the receiving cavity 11. Figure 1 As shown, along the forward direction of the cleaning equipment, the distance between the side of the receiving cavity 11 near the first spray hole 213 and the side of the first spray hole 213 away from the receiving cavity 11 is D1, and the distance between the side of the mounting cavity 14 near the first spray hole 213 and the side of the first spray hole 213 near the mounting cavity 14 is D2. D1 and D2 satisfy the relationship: 0.15≤D1÷D2≤0.35. When D1 and D2 satisfy this relationship, the roller component 21 will not be too close to the first spray hole 213, ensuring that stubborn stains can be fully melted and decomposed by the steam sprayed from the first spray hole 213, while the roller component 21 can clean away stubborn stains in a timely manner. Secondly, it can also ensure that the size of the cleaning equipment will not increase due to the distance between the middle sweeping component 50 and the first spray hole 213. The first spray hole 213 will not be too close to the middle sweeping component 50, thus reducing the steam spray speed and affecting the spray direction. The value of D1÷D2 can specifically include one of the following: 0.15, 0.16, 0.17, 0.18, 0.19, 0.2, 0.21, 0.22, 0.23, 0.24, 0.25, 0.26, 0.27, 0.28, 0.29, 0.3, 0.31, 0.32, 0.35, etc.

[0073] Combination Figure 2 and Figure 3As can be seen, the self-cleaning component 22 in this embodiment includes a water spray component 221 and a squeegee component 222. The water spray component 221 includes a mounting plate 2211 and a retaining plate 2212. The roller component 21 is connected to the mounting plate 2211. Specifically, the driving component of the roller component 21 is connected to the extension of the mounting plate 2211, and then the roller with the mop cloth is sleeved on the driving component and can rotate under the drive of the driving component. This is convenient to assemble and avoids complicating the overall structure of the cleaning component. The mounting plate 2211 is provided with a water supply channel and multiple second spray holes 2111. The water supply channel is laid along the axial direction of the roller component 21 (i.e., the length direction of the roller component 21). The retaining plate 2212 is disposed on the mounting plate 2211 and covers the water supply channel. The second spray holes 2111 are located on the side of the mounting plate 2211 near the roller component 21 and communicate with the water supply channel. After clean water is introduced into the water supply channel, it can be sprayed onto the roller through the second spray nozzle 2111 to fully wet the mop on the roller. Along the forward direction of the cleaning equipment, the squeegee 222 is connected to the side of the mounting plate 2211 away from the steam spray component 32 and abuts against the roller component 21. During the rotation of the roller, the squeegee 222 can scrape off the sewage and debris on the mop, thereby cleaning the roller component 21. The cleaning equipment also includes a sewage box 70, and the cleaning component 20 is located between the sewage box 70 and the steam spray component 32. The sewage scraped off by the squeegee 222 is discharged into the sewage box 70. In this embodiment, the spray component 221 is located between the squeegee 222 and the steam spray component 32, which not only cleans the roller component 21, but also improves the space utilization rate of the installation space inside the equipment body 10. Within a limited space, the cleaning equipment achieves self-cleaning of the roller component 21 and softening of stubborn stains through the steam spray component 32.

[0074] like Figure 8 As shown, the cleaning component 20 also includes a clean water tank 23 and a first water pump 24. The clean water tank 23 is installed inside the equipment body 10. The first water pump 24 is connected between the clean water tank 23 and the water supply channel. The first water pump 24 can transport the clean water in the clean water tank 23 to the water supply channel, thereby spraying clean water onto the roller component 21 through the second spray hole 2111.

[0075] The steam supply component 31 includes a steam generator 311 and a second water pump 312. The steam generator 311 is installed on the side of the equipment body 10 near the connecting pipe 322. The steam generator 311 includes an output port and an input port, with the output port communicating with the connecting pipe 322. Because the steam generator 311 is close to the connecting pipe 322, the length of the pipe connecting the output port and the connecting pipe 322 can be shortened, reducing the space occupied by the steam supply component 31 in the equipment body 10, thereby reserving sufficient space for the installation of other components. The first water pump 24 is installed inside the equipment body 10 and is connected between the clean water tank 23 and the input port, so that the first water pump 24 can transfer clean water from the clean water tank 23 to the steam generator 311. This embodiment reduces the space occupied by the equipment body 10 due to the separate installation of the steam supply component 31 and the self-cleaning component 22 in the same clean water tank 23, thereby improving the space utilization of the equipment body 10 and reducing the volume of the equipment body 10.

[0076] In addition, the cleaning equipment also includes a T-connector 60, which is installed inside the equipment body 10. The T-connector 60 includes a first interface, a second interface, and a third interface. The first interface is connected to the clean water tank 23, the second interface is connected to the first water pump 24, and the third interface is connected to the second water pump 312. In this embodiment, the first water pump 24 and the second water pump 312 are connected to the clean water tank 23 through the T-connector 60, thus only one water outlet channel 210 needs to be set on the clean water tank 23, reducing the number of connecting pipes between the clean water tank 23 and the first water pump 24 and the second water pump 312, making assembly more efficient and convenient. In order to enable the steam generator 311 to generate a larger amount of steam, the water flow rate output by the second water pump 312 in this embodiment is less than the water flow rate output by the first water pump 24, so that the steam generator 311 can heat the water into steam in time when it receives water from the second water pump 312, avoiding the impact of large water volume on steam generation.

[0077] Furthermore, the steam supply component 31 in this embodiment also includes a flow control switch, which is installed on the pipeline between the second water pump 312 and the inlet. The flow control switch is used to control the water flow rate at the inlet of the second water pump 312. This ensures that the user can adaptively control the water flow rate to the steam generator 311 by adjusting the flow control switch according to actual needs or desired steam emission effects. The flow control switch may include at least one of a needle valve, ball valve, butterfly valve, electric regulating valve, or pneumatic regulating valve.

[0078] like Figure 9As shown, the device body 10 in this embodiment includes a main housing component 12 and a base plate 13. The cleaning assembly 20, the intermediate sweeping assembly 50, the dust box, the wastewater tank, the clean water tank 23, the first water pump 24, the second water pump 312, the steam generator 311, and the tee connector 60 are all installed on the main housing component 12. The base plate 13 covers the bottom of the main housing component 12, and the steam injection component 32 is installed between the bottom of the main housing component 12 and the base plate 13. The base plate 13 provides stable support and protection for the steam injection component 32, improving the structural stability of the steam injection component 32 within the device body 10. Furthermore, the base plate 13 has at least a pre-drilled slot for exposing the roller brush 51 of the intermediate sweeping assembly 50. The base plate 13 is also provided with a plurality of clearance holes 131, which are arranged one-to-one with the plurality of first nozzles 213 of the steam injection component 32, so that the base plate 13 can support and fix the steam injection component 32 while the steam ejected from the first nozzles 213 can flow along the clearance holes 131 to the surface to be cleaned. In addition, the main body 321 of the steam injection component 32 is provided with a plurality of protrusions 214 on the side near the base plate 13, which are arranged one-to-one with the plurality of first nozzles 213, and the protrusions 214 are provided with guide holes communicating with the first nozzles 213. The ends of the protrusions 214 away from the main body 321 are arranged one-to-one with the plurality of clearance holes 131, and the guide holes are connected to the clearance holes 131. The steam ejected from the first nozzles 213 is sequentially sprayed along the guide holes and clearance holes 131 to the surface to be cleaned. Therefore, when there is an installation gap between the base plate 13 and the main body 321, the protrusion 214 can better guide the steam to the clearance hole 131, so as to prevent the steam from spreading between the base plate 13 and the main housing component 12, ensuring the amount of steam received by the surface to be cleaned, while avoiding damage to the components installed in the main housing component 12.
