[0038] As described in the background, the floor cleaning machine as a common household appliance plays a certain positive role in reducing housework and keeping the environment clean. Its working principle is to spray clean water in the clean water tank to the surface of the roller brush, and to rotate and rub the ground by means of the wet roller brush, so as to achieve the effect of cleaning stains. However, due to the type of stains, cleaning method or cleaning not in time, etc., stubborn stains may be left on the ground in daily life.

[0039] For this reason, the user usually needs to clean the stubborn stain area several times, or increase the pressure of the roller brush on the ground to ensure the cleaning effect of the stubborn stain, but this cleaning method may affect the service life of the roller brush. Of course, some floor cleaning machine products also spray hot water on the roller brush or directly spray hot water on the ground to promote the dissolution of stubborn stains and increase the stain removal ability, but the above cleaning method has limited cleaning effect on stubborn stains.

[0042] Reference will be made below to Figures 1 to 4 The cover plate assembly of the application is described. Among them, Figure 1 is the overall structure diagram of the cover plate assembly of the application; Figure 2 is the internal view of the cover plate assembly of the application; Figure 3 is the perspective view of the cover plate assembly of the application; Figure 4 is the bottom view of the cover plate assembly of the application.

[0043] As Figures 1 to 4As shown, in a preferred embodiment, the cover plate assembly comprises a body 10, a pump body 20, a first pipeline 30 and a spraying channel 40, wherein the body 10 comprises a first cover 11 and a second cover 12, the first cover 11 comprises an upper cover 111 and a lower cover 112, the upper cover 111 is connected with the lower cover 112, and the upper cover 111 and at least part of the lower cover 112 form a containing cavity, and the pump body 20 is arranged in the containing cavity. The lower cover 112 is provided with a first water inlet 1121 and a second water inlet 1122, the inlet of the pump body 20 is communicated with the first water inlet 1121 through the first pipeline 30, and the outlet of the pump body 20 is communicated with the second water inlet 1122 through a second pipeline (not shown in the figure). One end of the spraying channel 40 is communicated with the second water inlet 1122, and the other end of the spraying channel 40 forms a spraying opening. Specifically, the first cover 11 is connected with the second cover 12, the first cover 11 is located above the second cover 12, the bottom of the first cover 11 is provided with a first channel groove, the top of the second cover 12 is provided with a second channel groove, and the first channel groove and the corresponding second channel groove surround to form the spraying channel 40. The spraying channel 40 comprises a first sub-channel 41, a second sub-channel 42 and a third sub-channel 43, one end of the first sub-channel 41 is communicated with the second water inlet 1122, the other end of the first sub-channel 41 is communicated with one end of a plurality of second sub-channels 42, the other end of each second sub-channel 42 is communicated with one end of a plurality of third sub-channels 43, and the other end of the plurality of third sub-channels 43 forms a plurality of spraying openings, and the plurality of spraying openings are directed to the ground to be cleaned when the cover plate assembly is installed on the floor cleaning device.

[0044] In the embodiment, when the cover plate assembly is installed on the floor cleaning device, the first water inlet 1121 is communicated with a water storage tank of the floor cleaning device, wherein the water storage tank is used to store water or a mixture of water and cleaning agent. When the stubborn stain area of the ground is cleaned, the cleaning liquid enters the pump body 20 through the first water inlet 1121 and the first pipeline 30, and then enters the spraying channel 40 through the second pipeline and the second water inlet 1122 after being pressurized by the pump body 20. As shown in the figure, Figure 3 As shown, the spraying channel 40 comprises a first sub-channel 41, two second sub-channels 42 and four third sub-channels 43, that is, after the cleaning liquid enters the second water inlet 1122, the cleaning liquid first flows through the first sub-channel 41 and then is divided into the left and right second sub-channels 42, and the cleaning liquid continues to be divided into the corresponding two third sub-channels 43 of the second sub-channel 42 after flowing through each second sub-channel 42. The flow guide and distribution of the first sub-channel 41, the second sub-channel 42 and the third sub-channel 43 form four spraying paths, and the four spraying paths can realize uniform spraying and washing of the stubborn stain area of the ground.

[0045] It can be understood by those skilled in the art that although the spraying of the cleaning liquid is realized through the spraying channel 40 in the embodiment, the arrangement is not fixed, and in an alternative embodiment, a separate spraying member can be arranged on the body 10, and the water inlet of the spraying member is communicated with the outlet of the pump body 20, and the spraying of the stubborn stain area on the ground can also be realized, for example, a strip-shaped spraying member is arranged at the bottom of the lower cover 112, so that the sprayed cleaning liquid is linear, thereby realizing the large-area spraying of the stubborn stain area on the ground, and further improving the cleaning efficiency of the stubborn stain area on the ground. Of course, at this time, the arrangement of the second water inlet 1122 can also be omitted, as long as the communication between the outlet of the pump body 20 and the water inlet of the spraying member can be ensured. In addition, although the spraying channel 40 includes one first sub-channel 41, two second sub-channels 42 and four third sub-channels 43 in the embodiment, the specific arrangement of the spraying channel 40 is not fixed when the spraying channel 40 is arranged, and in an alternative embodiment, those skilled in the art can change the number of the first sub-channel 41, the second sub-channel 42 or the third sub-channel 43 according to the needs, to realize the adjustment of the number of the spraying ports, for example, a fourth sub-channel is added, and the fourth sub-channel is arranged as eight, at this time, the end of each third sub-channel 43 is communicated with two fourth sub-channels, and the end of each fourth sub-channel forms a spraying port, at this time, the number of spraying paths can be increased under the premise of ensuring uniform spraying, to realize the spraying of the stubborn stain area on the ground with a larger area.

[0046] It can also be understood by those skilled in the art that in the embodiment, in order to ensure that the cleaning liquid is uniformly sprayed to the stubborn stain area on the ground, the spraying channel 40 is arranged in a tree structure, and the length and diameter between the two second sub-channels 42 are equal, the length and diameter of the four third sub-channels 43 are equal, and the diameters of the first sub-channel 41, the second sub-channel 42 and the third sub-channel 43 are equal, but the arrangement is not necessarily fixed, and in an alternative embodiment, those skilled in the art can change the length and cross-sectional area of the first sub-channel 41, the second sub-channel 42 or the third sub-channel 43, for example, to further ensure the pressurization effect of the cleaning liquid, the cross-sectional area of the second sub-channel 42 or the third sub-channel 43 can be reduced. In another alternative embodiment, those skilled in the art can change the corresponding relationship between the first sub-channel 41 and the second sub-channel 42 or the second sub-channel 42 and the third sub-channel 43 according to the needs, for example, the first sub-channel 41 is divided into two second sub-channels 42, but each second sub-channel 42 is divided into three third sub-channels 43, at this time, six spraying paths can be formed, but considering the spraying effect of the cover plate assembly on the stubborn stain area on the ground, the spraying channel 40 is arranged in a tree structure, and the equal length and equal diameter between the second sub-channel 42 or the third sub-channel 43 is a relatively optimal choice.

[0047] It should be explained that, in this embodiment, the first channel groove at the bottom of the first cover 11 and the second channel groove at the top of the second cover 12 form a spray channel 40. That is, the bottom of the first cover 11 has a first channel groove relative to the upper portion of the first sub-channel 41, the second sub-channel 42, and the third sub-channel 43, and the top of the second cover 12 has a second channel groove relative to the lower portion of the first sub-channel 41, the second sub-channel 42, and the third sub-channel 43. When the first cover 11 and the second cover 12 are sealed and fastened together, the first channel groove and the second channel groove together form a complete through groove, which is the spray channel 40. Separating the first cover 11 and the second cover 12 simplifies the processing of the spray channel 40 and improves production efficiency; however, this separation is not mandatory. In an alternative embodiment, the second cover 12 can be omitted, and the spray channel 40 can be formed only on the first cover 11. In addition, although the first cover 11 is located above the second cover 12 in this embodiment, its arrangement is not necessary. In an alternative embodiment, the first cover 11 can be located below the second cover 12, and the spray channel 40 can still be formed through the first cover 11 and the second cover 12.

[0048] It should also be explained that, in this embodiment, independently setting the upper cover 111 and the lower cover 112 facilitates the processing of the first cover 11 and the installation of various components within the cavity. However, the specific setting of the first cover 11 is not mandatory; those skilled in the art can modify the specific setting of the first cover 11, such as its shape and connection method, as needed. Furthermore, although the first water inlet 1121 is located on the lower cover 112 in this embodiment, its location is not mandatory. Those skilled in the art can adjust the specific position of the first water inlet 1121 according to the specific water supply location of the floor cleaning device; for example, the first water inlet 1121 can be located on the side wall of the upper cover 111. In addition, the setting of the first pipe 30 and the second pipe is not fixed. In one alternative embodiment, when the spray element is independently set, one end of the second pipe is connected to the outlet of the pump body 20, and the other end is connected to the water inlet of the spray element. In another alternative embodiment, those skilled in the art can omit the setting of the first pipe 30 or the second pipe as needed; for example, the other end of the second pipe can be directly connected to the water inlet of the spray element.

[0049] In a possible implementation, the cover plate assembly further comprises a heating module (not shown in the figure), which can be arranged in the accommodating cavity and located between the outlet of the pump body 20 and the second water inlet 1122. Specifically, the heating module can be a PTC heater, and the PTC heater is arranged in the second pipeline. When the cleaning liquid passes through the second pipeline, the PTC heater can heat the cleaning liquid, and the dual functions of water pressure washing and hot water dissolving stains can further improve the cleaning effect on the stubborn stain area of the ground.

[0050] It should be explained that the arrangement of the heating module is not fixed. In an alternative implementation, the arrangement of the heating module can be omitted. In this case, the stubborn stain area of the ground can be washed only by water pressure, or the cover plate assembly can be directly supplied with hot water by the floor cleaning device. In another alternative implementation, a person skilled in the art can select the specific type of the heating module or change the arrangement position of the heating module according to the needs, for example, the heating module can be arranged between the first water inlet and the inlet of the pump body, or the heating module can be an electric heater.

[0051] The application further provides a floor cleaning device comprising the cover plate assembly.

[0052] With the above technical solution, when the floor cleaning device is connected with the cover plate assembly, the cleaning liquid in the water storage tank can enter the cover plate assembly. When the floor cleaning device cleans the stubborn stain area of the ground, the cleaning liquid can be pressurized by the pump body, and then the cleaning liquid is sprayed to the stubborn stain area of the ground through the spray port, so that the water pressure is used to effectively and quickly spray and wash the stubborn stain area of the ground.

[0053] Further, the cover plate assembly and the floor cleaning device are detachably connected.

[0054] The cover plate assembly will be described below in combination with a floor cleaning device, Figure 5 The cover plate assembly will be described below in combination with a floor cleaning device, Figure 5 is a schematic view of a floor cleaning device according to an embodiment of the application.

[0055] As Figure 5As shown, in a possible implementation, the ground cleaning device 50 is provided with a cover plate 60, and the cover plate 60 is detachably connected with the ground cleaning device 50. The user can replace the cover plate according to the needs. For example, when the user performs general cleaning on the ground by using the scrubber, the cover plate 60 is installed to the ground cleaning device 50. When the user needs to clean the stubborn stain area on the ground by using the scrubber, the user can detach the cover plate 60 and install the cover plate assembly of the present application to the ground cleaning device 50. That is, the modular design of the cover plate assembly of the present application is beneficial for the user to select the corresponding cover plate according to the needs for timely replacement. Of course, the detachable connection of the cover plate assembly of the present application and the ground cleaning device is not necessary. In a replaceable implementation, the cover plate assembly of the present application can be fixedly connected with the ground cleaning device. At this time, all the cleaning areas can be cleaned by spraying to improve the cleaning effect of the ground cleaning device.
