Example

[0025] As shown in Figures 1 and 2, this embodiment provides a media spraying device 100, which can be applied in cleaning equipment to spray cleaning media onto the surface or parts to be cleaned, thereby improving the cleaning effect on the surface to be cleaned.

[0026] Furthermore, the medium ejection device 100 may include a medium ejection plate 110, a medium inlet 120 disposed on the medium ejection plate 110, a medium diversion channel 130 disposed in the medium ejection plate 110, and a medium ejection structure 140 disposed in the medium ejection plate 110, wherein the medium inlet 120 is connected to the medium diversion channel 130, and the medium ejection structure 140 is connected to the end of the medium diversion channel 130. Steam, water, and other cleaning media can be transported to the media distribution channel 130 in the media spraying plate 110 through the media inlet 120. When the cleaning media passes through the media spraying structure 140 connected at the end of the media distribution channel 130, the media spraying structure 140 can pressurize the cleaning media, which can increase the spray pressure when the cleaning media is sprayed, enhance the atomization and vaporization effect of the cleaning media, increase the amount of steam generated by the cleaning media, and reduce the water content in the steam. This can reduce the temperature loss of the cleaning media and improve and enhance the cleaning effect.

[0027] Specifically, as shown in Figure 3, the media ejection plate 110 may include an ejection plate base plate 112 and an ejection plate cover plate 114 that covers the ejection plate base plate 112. A media diversion channel 130 may be formed between the ejection plate base plate 112 and the ejection plate cover plate 114, and a media inlet 120 may be provided on the ejection cover plate 114 or the ejection plate base plate 112.

[0028] Furthermore, the ejector plate base plate 112 may be provided with a first flow channel groove, and the ejector plate cover plate 114 is placed on the ejector plate base plate 112 to close the first flow channel groove as a medium diversion channel 130; or, the ejector plate cover plate 114 may be provided with a second flow channel groove, and the ejector plate base plate 112 and the ejector plate cover plate 114 are stacked to close the second flow channel groove as a medium diversion channel 130; or, the ejector plate base plate 112 may be provided with a first flow channel groove, and the ejector plate cover plate 114 may be provided with a corresponding second flow channel groove, and the ejector plate cover plate 114 is placed on the ejector plate base plate 112 to close the first flow channel groove and the second flow channel groove as a medium diversion channel 130. Furthermore, a sealing protrusion is provided on one of the ejector plate base plate 112 and the ejector plate cover plate 114, and a sealing groove is provided on the other. The sealing protrusion is correspondingly engaged in the sealing groove. This not only ensures a tight fit between the ejector plate base plate 112 and the ejector plate cover plate 114, but also seals the media distribution channel 130 to prevent leakage of the cleaning medium. Moreover, to better seal the media distribution channel 130, the corresponding sealing protrusion and sealing groove can be arranged around the outer periphery of the media distribution channel 130, sealing the media distribution channel 130 from the outside. In addition, some of the corresponding sealing protrusions and sealing grooves can be arranged around the outer periphery of the media distribution channel 130, and some of the corresponding sealing protrusions and sealing grooves can be arranged inside the media distribution channel 130, sealing it from both the inside and outside simultaneously.

[0029] Furthermore, as shown in Figures 1 and 2, the media inlet 120 on the media spray plate 110 may have at least two inlets, and all media inlets 120 are connected to the media distribution channel 130. Cleaning media can be delivered to the media distribution channel 130 of the media spray plate 110 from multiple locations through multiple media inlets 120. This ensures that even if one or more media inlets 120 are blocked or damaged, cleaning media can still be delivered to the media distribution channel 130 through other intact and unobstructed media inlets 120, without affecting the spraying and cleaning effect of the media spraying device 100. In addition, each media inlet 120 can be connected to a media input pipe, through which cleaning media can be delivered to the media inlet 120.

[0030] In this embodiment, a media inlet 120 can be provided at each end of the media ejection plate 110, and the two media inlet ports 120 can be connected to the media diversion channel 130 in the media ejection plate 110 from both ends. When both media inlet ports 120 are intact and unobstructed, cleaning media can be delivered to the media diversion channel 130 simultaneously through the media inlet ports 120 at both ends; when the media inlet port 120 at one end is blocked or damaged, cleaning media can be delivered to the media diversion channel 130 through the media inlet port 120 at the other end.

[0031] The two media inlet ports 120 can be used to input different fluids; for example, one media inlet port 120 can be used to input hot water or steam, and the other media inlet port 120 can be used to input cold water. The inlet diameters of the two media inlet ports 120 are different, as shown in the attached diagram. Figure 4 As shown, the diameter of the medium inlet 120 at one end is larger than the diameter of the medium inlet 120 at the other end. Specifically, the medium inlet with the larger diameter is used to transport hot water or steam, while the medium inlet with the smaller diameter is used to transport cold water.

[0032] In addition, the two media inlet ports 120 can be located at both ends of the media ejection plate 110, or at the middle of the media ejection plate 110, or one of the media inlet ports 120 can be located at the middle of the media ejection plate 110 and the other media inlet port 120 can be located at the end of the media ejection plate 110.

[0033] Moreover, in this embodiment, the medium inlet 120 can be a connecting pipe joint installed on the medium ejection plate 110. One end of the connecting pipe joint can be connected to an external medium inlet pipe, and the other end can be connected to the medium diversion channel 130.

[0034] In addition, depending on actual needs, one media inlet 120 may be provided on the media ejection plate 110, or three or more media inlet ports 120 may be provided. Moreover, the location of each media inlet port 120 may also be set as needed.

[0035] Furthermore, as shown in Figures 4 and 6, the media diversion channel 130 in the media ejection plate 110 can be configured as a multi-stage diversion channel. This multi-stage diversion channel allows for the diversion of the cleaning medium in the input medium diversion channel 130, enabling the cleaning medium to be ejected from multiple media ejection structures to the outside of the media ejection plate 110 after multi-stage diversion. Moreover, the media diversion channel 130 can be configured as a two-stage or more-than-two-stage channel to divert the cleaning medium two or more times.

[0036] Specifically, the multi-stage diversion channel may include an upper-level diversion channel connected to the media inlet 120, and at least one lower-level diversion channel connected to the upper-level diversion channel. Each lower-level diversion channel is connected to the media ejection structure 140, and the cross-sectional area of ​​the lower-level diversion channel is smaller than that of the upper-level diversion channel. Because the cross-sectional area of ​​the lower-level diversion channel is smaller than that of the upper-level diversion channel, the cleaning medium is pressurized when it flows from the upper-level diversion channel to the lower-level diversion channel. This pre-pressurizes the cleaning medium before it enters the media ejection structure 140 and exits the media ejection plate 110, further increasing the ejection pressure of the cleaning medium.

[0037] Furthermore, the multi-level distribution channel may include one lower-level distribution channel connected to the upper-level distribution channel, or it may include multiple lower-level distribution channels connected to the upper-level distribution channel. Moreover, each lower-level distribution channel may be connected to at least one sub-lower-level distribution channel, and each sub-lower-level distribution channel may be connected to at least one sub-sub-sub-level distribution channel. And so on, the medium distribution channel 130 may be configured as an N-level distribution channel, which may include n sequentially connected lower-level distribution channels, each of which may have at least one. Here, N is a positive integer greater than or equal to 2, and n is a positive integer greater than or equal to 3.

[0038] Furthermore, the end of the final lower-level branch channel of the media branch channel 130 can be connected to a media pressurization ejection structure 140. Moreover, the cross-sectional area of ​​the final lower-level branch channel can be made smaller than that of the upper-level branch channel, while the cross-sectional area of ​​the lower-level branch channel between the upper-level branch channel connected to the media inlet 120 and the final lower-level branch channel can be smaller than or equal to the cross-sectional area of ​​the upper-level branch channel, so as to facilitate at least one pressurization of the cleaning medium entering the media ejection structure 140.

[0039] Furthermore, the cross-sectional area of ​​each lower-level branch channel in the multi-stage branch channel can decrease sequentially from the upper-level branch channel to the final lower-level branch channel, thereby sequentially pressurizing the cleaning medium in the multi-stage branch channel. This multi-stage pressurization of the cleaning medium better enhances the ejection pressure of the cleaning medium. In addition, there can be multiple final-level branch channels, and correspondingly multiple media ejection structures 140, allowing for uniform ejection of the cleaning medium from multiple locations.

[0040] In this embodiment, as shown in FIG4, the medium diversion channel 130 can be configured as a three-stage diversion channel.

[0041] Specifically, the three-stage diversion channel may include a first-stage diversion channel 132 (equivalent to an upper-level diversion channel in a multi-stage diversion channel) connected to all media inlets 120, at least one second-stage diversion channel 134 (equivalent to a lower-level diversion channel connected to the upper-level diversion channel) connected to the first-stage diversion channel 132, and one third-stage diversion channel 136 (equivalent to a sub-lower-level diversion channel connected to the lower-level diversion channel) connected to both ends of the second-stage diversion channel 134, with each end of the third-stage diversion channel 136 correspondingly connected to a media ejection structure 140. In this way, the cleaning medium entering the media diversion channel 130 can be diverted three times, delivering the cleaning medium to multiple media ejection structures 140.

[0042] Furthermore, the cross-sectional area values ​​of the first-stage diversion channel 132, the second-stage diversion channel 134, and the third-stage diversion channel 136 of the media diversion channel 130 decrease sequentially, thereby enabling the cleaning medium in the media diversion channel 130 to be pressurized three times, so that the cleaning medium can be delivered to the media ejection structure 140 at a higher pressure.

[0043] In addition, depending on the needs, the medium diversion channel 130 can also be configured as a two-stage diversion channel, or a four-stage diversion channel (as shown in Figure 6), or a five-stage diversion channel, etc.

[0044] Furthermore, as shown in Figures 3 and 4, the media ejection structure 140 may include a media ejection channel 142 disposed in the media ejection plate 110, the cross-sectional area of ​​the media ejection channel 142 being smaller than the cross-sectional area of ​​the media diversion channel 130. After the cleaning medium enters the media ejection channel 142 through the media diversion channel 130, the smaller cross-sectional area of ​​the media ejection channel 142 allows for pressurization of the cleaning medium, increasing the ejection pressure of the cleaning medium. Moreover, given the pressurization of the cleaning medium by the media diversion channel 130, the media ejection channel 142 can further pressurize the cleaning medium, further improving the ejection pressure, vaporization and atomization effect, reducing steam moisture content, and minimizing temperature loss, thereby further enhancing the cleaning effect.

[0045] Furthermore, a transition section 1422 may be provided at the connection point between the media outlet channel 142 and the media distribution channel 130. The transition section 1422 may be designed as a constricted shape. By designing the part connecting the media outlet channel 142 and the media distribution channel 130 (the transition section 1422) as a constricted transition flared shape (i.e., a narrowed shape) of a certain size, it is beneficial to achieve pressure concentration of the cleaning medium when it enters the media outlet channel 142 from the media distribution channel 130, thus facilitating the stable flow of the cleaning medium into the media outlet channel 142.

[0046] Furthermore, a medium outlet 1424 may be provided at the end of the medium ejection channel 142, and the medium outlet 1424 may be configured as a flared shape. By designing the end outlet of the medium ejection channel 142 (i.e., the medium outlet 1424) as a flared funnel shape with a certain size, the vaporized cleaning medium after being pressurized by the medium ejection channel 142 can diffuse at high speed. This is more conducive to increasing the injection pressure of the cleaning medium and achieving complete vaporization.

[0047] Furthermore, the inlet of the media ejection channel 142 can be located above the bottom wall of the media diversion channel 130, ensuring that the height of the media ejection channel 142 is greater than that of the media diversion channel 130. This prevents residual liquid cleaning medium on the bottom wall of the media diversion channel 130 from easily entering the media ejection channel 142, thus avoiding leakage of residual liquid cleaning medium from inside the media ejection device 100 to the outside and affecting the user experience. Further, the inlet of the media ejection channel 142 can be positioned in the upper-middle position of the cross-section of the media diversion channel 130, providing better leak prevention and reducing water content during steam injection, resulting in better steam ejection. After sufficient atomization, the steam enters the media ejection structure 140 from the inlet located in the upper-middle position of the cross-section and is ejected.

[0048] Furthermore, at least a portion of the media ejection channel 142 can be a cylindrical channel, meaning the cross-sectional shape of the media pressurization ejection channel 142 is circular. Specifically, the main body of the media ejection channel 142 can be cylindrical to make the cleaning medium flow more stably and eject more uniformly. Further, the media ejection channel 142 includes an ejection channel body located between the transition connection section 1422 and the media outlet 1424, the ejection channel body being cylindrical, while both the transition connection section 1422 and the media outlet 1424 can be frustum-shaped.

[0049] Furthermore, the diameter of the medium ejection channel 142 can range from 0.3 to 1 mm. The diameter of the transition section 1422 gradually decreases from 1 mm to 0.3 mm, while the diameter of the medium ejection outlet 1424 gradually increases from 0.3 mm to 1 mm. The specific diameters of the transition section 1422, the medium ejection outlet 1424, and the main body of the ejection channel can be selected within the range of 0.3 to 1 mm based on actual conditions, so that the medium ejection channel 142 has good pressurization, atomization, and vaporization effects.

[0050] Furthermore, the length of the media ejection channel 142 can be greater than or equal to 3 mm, allowing sufficient pressurization time for the cleaning medium as it passes through the media ejection channel 142. Specifically, the overall length of the media ejection channel 142 can be greater than or equal to 3 mm, and the length of the main body of the ejection channel 142 can also be greater than or equal to 3 mm.

[0051] Furthermore, the medium ejection channel 142 may only include a constricted transition connecting section 1422 and the ejection channel body, or only include the ejection channel body and a flared medium ejection outlet 1424, or only include the ejection channel body, or only include the medium ejection outlet 1424. In addition to a circular cross-section, the cross-section of the medium ejection channel 142 may also be a regular shape such as a rectangle, triangle, or trapezoid, or other irregular shapes.

[0052] Furthermore, as shown in Figures 5 and 6, the media ejection structure 140 may also include a media pressurizing nozzle 144 installed in the media ejection plate 110. The media pressurizing nozzle 144 is connected to the end of the media distribution channel 130, and can also pressurize the cleaning medium delivered from the media distribution channel 130 before ejecting it. This can also increase the ejection pressure of the cleaning medium, improve the vaporization and atomization effect, reduce the steam moisture content, reduce temperature loss, and further improve the cleaning effect.

[0053] Furthermore, the medium pressurization nozzle 144 can be an existing high-pressure nozzle or high-pressure nozzle head. High-pressure nozzles or high-pressure nozzles are nozzles that spray mist through high-pressure jets, achieving excellent spraying effects. Their working principle involves constricting the cross-sectional area of ​​the nozzle's inner orifice to convert the pressure energy of the high-pressure medium into kinetic energy, which is then ejected from the nozzle as a high-pressure medium jet.

[0054] Furthermore, in this embodiment, the cleaning medium can be hot water, steam, room temperature water, etc. Additionally, depending on the need, the cleaning medium can also be a special mixture with cleaning effects. Example

[0055] As shown in Figure 7, this embodiment provides a floor brush assembly 10, including a floor brush housing 200 and a media spraying device 100 disposed on the floor brush housing 200. The floor brush housing 200 may be provided with a media input pipe, which is connected to the media input port 120 on the media spraying plate 110 of the media spraying device 100, so that the cleaning media is transported through the media input pipe to the media distribution channel of the media spraying plate 110.

[0056] In this embodiment, a media input pipe is provided on each side of the floor brush housing 200, which is connected to a media input port 120 on each side of the media spraying plate 110 of the media spraying device 100, so that cleaning media can be input into the media spraying device 100 from both sides respectively.

[0057] Furthermore, the floor brush assembly may also include cleaning components such as a cleaning roller brush disposed on the floor brush housing 200. Multiple media spraying structures 140 on the media spraying plate 110 of the media spraying device 100 can correspond to the cleaning components, and can spray the atomized and vaporized cleaning media onto the cleaning components to improve the cleaning effect of the floor brush assembly. Example

[0058] This embodiment provides a cleaning device, including a device body and a floor brush assembly mounted on the device body. By providing a medium spraying device 100 with a pressurized atomization function on the floor brush assembly of the cleaning device, the steam generation pressure and steam atomization effect of the cleaning medium can be increased. At the same time, the temperature of the cleaning components (such as cleaning rollers) of the floor brush assembly can be increased, the amount of residual water on the ground can be reduced, and the risk-bearing capacity of the steam outlet end of the water circuit of the whole machine can be increased.

[0059] In this embodiment, the cleaning equipment can be a floor scrubber, a floor mop, etc.

[0060] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
