[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Reference below Figure 1-Figure 7 A cleaning device 1000 according to an embodiment of the present invention is described.

[0036] like Figure 1-Figure 2 As shown, a cleaning device 1000 according to an embodiment of the present invention includes: a floor brush assembly 100 and a sewage tank 200, the floor brush assembly 100 includes a floor brush housing 10, the floor brush housing 10 has a fan cavity and an air inlet 121 connected to the fan cavity; the sewage tank 200 is arranged on the upper side of the floor brush housing 10 and is detachably connected to the floor brush housing 10, the inner side of the sewage tank 200 defines a sewage cavity 201, and the air inlet 121 is located on the outer side of the sewage tank 200 and is connected to the sewage cavity 201.

[0037] Specifically, the fan chamber inside the floor brush housing 10 is used to accommodate the fan 500, and the floor brush housing 10 can provide an installation space for the fan 500; the sewage chamber 201 formed inside the sewage tank 200 is mainly used to accommodate sewage; the sewage tank 200 and the floor brush housing 10 are detachable, which can facilitate the discharge of sewage in the sewage chamber 201 and facilitate the cleaning of the sewage tank 200; the two ends of the air inlet 121 are respectively connected to the fan chamber and the sewage chamber 201, so that the fan 500 can do work on the air in the sewage chamber 201, so that a negative pressure is formed in the sewage chamber 201, and then the sewage on the ground can be sucked into the sewage tank 200; at the same time, the air inlet 121 is located on the outside of the sewage tank 200, so that after the sewage tank 200 is removed, the failure and damage of the fan 500 caused by the dripping sewage entering the fan 500 through the air inlet 121 can be effectively avoided, thereby improving the service life and working performance of the fan 500.

[0038] When the cleaning device 1000 is working, the fan 500 is turned on, and the fan 500 draws the air in the sewage chamber 201 to the outside of the sewage chamber 201 through the air inlet 121, so that a negative pressure is generated in the sewage chamber 201, and then the sewage on the ground is sucked into the sewage chamber 201, and the floor is cleaned. When the cleaning is completed, the sewage tank 200 is removed from the floor brush housing 10 and transferred to the wash basin, and then the sewage is discharged and the sewage tank 200 is cleaned, and finally the cleaned sewage tank 200 is installed back on the floor brush housing 10.

[0039] According to the cleaning device 1000 of the embodiment of the present invention, by locating the air inlet 121 on the outside of the sewage tank 200 and connecting it with the sewage chamber 201, the normal operation of the cleaning device 1000 can be ensured. At the same time, it can also effectively avoid the sewage dripping from the sewage tank 200 entering the fan 500 through the air inlet 121, which may cause malfunction and damage to the fan 500, thereby improving the service life and working performance of the fan 500.

[0040] According to some embodiments of the present invention, in the horizontal projection plane, the projection of the air inlet 121 is arranged at intervals from the projection of the sewage chamber 201. That is, the air inlet 121 is arranged outside the sewage chamber 201, which can effectively reduce the risk of water entering the fan chamber through the air inlet 121, thereby improving the working stability and service life of the fan 500.

[0041] According to some embodiments of the present invention, Figure 1-Figure 2 As shown, the floor brush housing 10 has a shell body 11 and an extension column 12, the fan cavity is arranged in the shell body 11, one end of the extension column 12 is connected to the shell body 11 and the other end extends vertically upward, the inner side of the extension column 12 defines an air inlet duct 122 extending vertically, and an air inlet 121 is formed at the other end of the extension column 12. Among them, the shell body 11 can be used to provide an installation space for the fan 500, and at the same time, it can also play a certain protective role for the fan 500, which can prevent external impurities from entering the fan cavity, thereby improving the safety of the fan 500; the air inlet duct 122 defined inside the extension column 12 can play a guiding role, which can facilitate the air in the sewage cavity 201 to be sucked out of the sewage tank 200, so as to ensure the normal operation of the cleaning device.

[0042] At the same time, the air inlet 121 is formed with the other end of the extension column 12, so that the air inlet 121 can be kept away from the shell body 11, and the air inlet 121 of the fan 500 can be higher than the bottom of the sewage tank 200, thereby effectively reducing the risk of sewage entering the fan cavity through the air inlet 121, thereby improving the working stability and service life of the fan 500.

[0043] According to some embodiments of the present invention, Figure 1-Figure 2 As shown, the end surface of the other end of the extension column 12 is formed on an inclined surface inclined relative to the horizontal direction, and the air inlet 121 passes through the end surface of the other end of the extension column 12. In this way, the air inlet 121 can be easily connected to the sewage chamber 201. At the same time, after the sewage tank 200 is removed, impurities can be effectively prevented from falling directly into the air inlet 121, thereby effectively reducing the risk of sewage or other impurities entering the fan chamber through the air inlet 121, thereby improving the working stability and service life of the fan 500.

[0044] According to some embodiments of the present invention, the angle between the end surface of the other end of the extension column 12 and the horizontal plane is greater than or equal to 45°. For example, the angle between the other end surface of the extension column 12 and the horizontal plane can be 45°, 50°, 55°, 60° or above. In this way, after the sewage tank 200 is removed, impurities can be effectively prevented from falling directly into the air inlet 121, thereby effectively reducing the risk of sewage or other impurities entering the fan cavity through the air inlet 121, thereby improving the working stability and service life of the fan 500.

[0045] For example Figure 1 As shown, the end surface of the other end of the extension column 12 extends backward and tilts in the direction of the extension column 12 from bottom to top, and the inclined surface is arranged toward the sewage tank 200 .

[0046] According to some embodiments of the present invention, in the up-down direction, the ratio of the distance between the air inlet 121 and the end of the sewage tank 200 connected to the shell body 11 to the height of the sewage tank 200 is greater than or equal to 1 / 3. For example, the ratio of the distance between the air inlet 121 and the end of the sewage tank 200 connected to the shell body 11 to the height of the sewage tank 200 may be 1 / 3, 2 / 3 or 1. In this way, it can be ensured that the air inlet 121 is much higher than the bottom of the sewage tank 200, and then it can be effectively prevented that water enters the fan 500 from the air inlet 121 when the sewage tank 200 is removed, thereby ensuring the service life and working performance of the fan 500.

[0047] Optionally, the extension column 12 is integrally formed with at least part of the shell body 11. That is, the extension column 12 can be integrally formed with part of the shell, or can be integrally formed with the shell in its entirety, so that the assembly steps of the cleaning device 1000 can be reduced, the assembly efficiency of the cleaning device 1000 can be improved, and at the same time, the position of the sealing member can be reduced, thereby improving the sealing performance of the air inlet duct 122, and thereby improving the safety of the cleaning device 1000.

[0048] According to some embodiments of the present invention, Figure 2 As shown, a suction duct 202 is formed in the sewage tank 200, the inlet end of the suction duct 202 is connected to the sewage chamber 201, and the outlet end of the suction duct 202 is connected to and connected to the air inlet 121. The suction duct 202 can be used to limit the movement direction of the wind, so that the air in the sewage chamber 201 can enter the fan 500 along the suction duct 202, thereby improving the working efficiency of the fan 500, thereby improving the working efficiency of the cleaning device 1000.

[0049] According to some embodiments of the present invention, Figure 2 As shown, in the direction from the inlet end of the air suction duct 202 toward the outlet end, the air suction duct 202 extends downwardly in a direction toward the air inlet 121. That is, the inlet end of the air suction duct 202 is higher than the air inlet 121, which can make the air flow channel smoother, facilitate the smooth flow of air flow, reduce the work done by the fan 500, and thus reduce the energy consumption of the fan 500.

[0050] According to some embodiments of the present invention, Figure 2As shown, the cleaning device 1000 further includes a sealing connector 300, which is sealingly connected to the periphery of the outlet end of the air suction duct 202 and the periphery of the air inlet 121. The sealing connector 300 can be used to seal the gap between the outlet end of the air suction duct 202 and the air inlet 121, which can further improve the sealing effect between the air suction duct 202 and the air inlet duct 122, thereby ensuring the normal operation of the cleaning device 1000.

[0051] Optionally, the sealing connector 300 is a flexible member having a certain compressibility, so that when the air inlet 121 is connected to the air suction duct 202, an extrusion seal can be generated, which can further increase the tightness of the connection between the air suction duct 202 and the air inlet 121, thereby ensuring normal air suction of the fan 500.

[0052] According to some embodiments of the present invention, Figure 2 As shown, a liquid level detector is provided in the sewage chamber 201, and the liquid level detector is configured to detect the liquid level in the sewage chamber 201. When the liquid level reaches a certain position, the liquid level detector can send a signal to stop the cleaning device 1000 from working, thereby preventing the blower 500 from being damaged due to the sewage level in the sewage chamber 201 being too high, which causes the sewage to enter the blower 500 through the air suction duct 202. The liquid level detector can include various types, such as ultrasonic level gauges, float level gauges, etc.

[0053] According to some embodiments of the present invention, Figure 2 As shown, the liquid level detector includes a float 400, and the float 400 is configured to block the inlet end of the suction air duct 202 under the condition that the liquid level in the sewage chamber 201 reaches a preset threshold. The preset threshold may be a preset value set according to the maximum height that the sewage can reach in the sewage chamber 201. When the liquid level reaches the preset threshold, the float 400 can block the inlet end of the suction port, thereby blocking the air flow from continuing to flow, causing the cleaning device 1000 to stop working. At the same time, it can also prevent the sewage from being sucked into the fan 500 through the suction air duct 202, causing the fan 500 to malfunction or damage.

[0054] According to some embodiments of the present invention, Figure 2 As shown, the sewage tank 200 further includes: a sewage inlet pipe 203, one end of the sewage inlet pipe 203 (for example Figure 2 The lower end of the sewage inlet pipe 203 shown in FIG. 200 is connected to the area to be cleaned, and the other end of the sewage inlet pipe 203 (for example Figure 2The upper end of the sewage inlet pipe 203 as shown in the figure extends into the sewage chamber 201 and communicates with the sewage chamber 201, and the other end of the sewage inlet pipe 203 extends upward to the upper space of the sewage chamber 201. In this way, it can effectively prevent the sewage sucked into the sewage chamber 201 from flowing back to the area to be cleaned through the sewage inlet pipe 203, thereby ensuring the normal operation of the cleaning device 1000.

[0055] According to some embodiments of the present invention, Figure 2 As shown, the inlet end of the air suction duct 202 is formed at the upper part of the sewage chamber 201, and the sewage tank 200 further includes a baffle 204, which is arranged in the sewage chamber 201, the upper end of the baffle 204 is connected to the top wall of the sewage chamber 201 and the lower end extends downward, and the other end of the sewage air inlet pipe and the inlet end of the air suction duct 202 are respectively located on both sides of the baffle 204. In this way, the sewage carried by the air flow can enter the sewage chamber 201 and then be blocked by the baffle 204 and slide into the sewage tank 200, which can prevent the sewage from entering the fan 500 through the air suction duct 202, thereby improving the use safety and service life of the fan 500.

[0056] In some specific embodiments, the cleaning device 1000 is a floor scrubber, such as Figure 3-Figure 4 As shown, the floor brush assembly 100 also includes: a floor brush base 111, a roller brush 20 and a trash box 30.

That is, the water leakage hole 34 can be formed as a long strip hole extending in the front-to-back direction, or can be formed as a long strip hole extending in the left-to-right direction, or can include a long strip hole extending in the front-to-back direction and a long strip hole extending in the left-to-right direction. Among them, the width of the long strip hole has certain size requirements, so that the long strip hole can effectively prevent the particle garbage from falling through the long strip hole while ensuring that the sewage leaks from the garbage box 30 to the ground, thereby ensuring the normal use of the garbage box 30.

[0072] In some specific embodiments, Figure 7As shown, there are multiple water leakage holes 34, and the multiple water leakage holes 34 are arranged at intervals on the bottom wall of the garbage cavity. For example, there can be two, three or more water leakage holes 34. Among them, the multiple water leakage holes 34 are arranged at intervals on the bottom wall of the garbage cavity, which can ensure that sewage is discharged from the garbage box 30, and at the same time, it can also effectively prevent granular garbage from falling to the ground, thereby ensuring the normal use of the garbage box 30.

[0073] Furthermore, the garbage box 30 extends in the left and right directions to form a long strip-shaped box body, and the length can be adapted to the length of the roller brush 20, so that all the garbage kicked up by the roller brush 20 can be collected in the garbage box 30, and the accumulation of garbage between the roller brush 20 and the floor brush base 111 can be further avoided, thereby effectively solving the problem that the garbage on the forearm of the floor brush base 111 is difficult to clean, reducing the difficulty of users cleaning the machine and improving the user experience.

[0074] In some specific embodiments, the floor brush assembly 100 also includes a floor brush upper cover 112, which is arranged on the upper side of the floor brush base 111, and together define a fan cavity, and the fan 500 is arranged in the fan cavity; the sewage tank 200 is arranged on the upper side of the floor brush upper cover 112; the extension column 12 extends out of the floor brush upper cover 112 and continues to extend upward, so that the air inlet 121 is much higher than the upper surface of the floor brush upper cover 112, so that it is difficult for sewage to enter the fan cavity through the air inlet 121, thereby improving the safety of the cleaning device 1000.
