The drain pipe 13 and the clean water supply pipe are both flexible hoses, so that the main body 10 can be kept still during the cleaning operation, and only the floor brush assembly 30 and the operating lever 12 are operated, so that the corresponding operation volume is smaller, the weight is lighter, and the operation comfort is improved.

Clear water is sprayed on the rolling brush or the ground, sewage is generated after the rolling brush is dragged, the sewage is sucked and recovered as soon as possible, and the risk of secondary pollution to the ground caused by the sewage is reduced. In an embodiment, referring to fig. 3, the suction port of the floor brush assembly 30 includes a suction port 380 communicated with the lower end of the sewage pipe 13, and the sewage collected by the first roller brush 341 and the second roller brush 342 enters the sewage pipe 13 through the suction port 380. The floor brush assembly 30 further comprises a first drainage channel 330 and a second drainage channel 332, one end of the first drainage channel 330 is communicated with the dirt suction port 380, and the other end is arranged facing the first rolling brush 341 as a front suction port for guiding the sewage collected by the first rolling brush 341 to the dirt suction port 380. Accordingly, one end of the second drainage channel 332 communicates with the soil suction port 380, and the other end is disposed facing the second round brush 342 as a rear suction port, for guiding the sewage collected by the second round brush 342 to the soil suction port 380. Finally, the sewage is collected to the sewage suction port 380 through the first drainage channel 330 and the second drainage channel 332, and is sucked into the sewage discharge pipe 13 through the sewage suction port 380.

The sewage suction port 380, the first drainage channel 330 and the second drainage channel 332 are all located between the first rolling brush 341 and the second rolling brush 342, and under the negative pressure effect, sewage collected by the first rolling brush 341 and the second rolling brush 342 is sucked by the first drainage channel 330 and the second drainage channel 332, collected to the sewage suction port 380, flows into the sewage recovery barrel 40 through the sewage discharge pipeline 13, and is temporarily stored in the sewage recovery barrel 40. Specifically, the first drainage channel 330, the suction port 380, and the second drainage channel 332 are arranged in this order. More specifically, the first drainage channel 330, the dirt suction port 380, and the second drainage channel 332 are arranged in this order in the front-rear direction, and the distance between the dirt suction port 380 and the first drainage channel 330 and the distance between the dirt suction port 380 and the second drainage channel 332 are substantially the same.

In this embodiment, the inner upper surface of at least one of the first flow guiding channel 330 and the second flow guiding channel 332 extends obliquely upwards, and the upper surface and the working surface have an inclination angle α therebetween, wherein the inclination angle α ranges from more than 0 ° to less than 90 °. That is to say, the inner upper surface of the first diversion channel 330 and/or the inner upper surface of the second diversion channel 332 are arranged in a non-parallel manner, so that the sewage obliquely ascends along the inner upper surface of the first diversion channel 330 and/or the inner upper surface of the second diversion channel 332, the sewage can flow towards the sewage discharge pipeline 13 under the action of air flow, and the sewage recovery efficiency is improved. Specifically, the inclination angle α is formed at a position where the inner upper surfaces of the first drainage channel 330 and the second drainage channel 332 are adjacent to the sewage suction port 380, where the inner upper walls of the first drainage channel 330 and the second drainage channel 332 are adjacent to the side wall of the sewage suction port 380, and a bending transition is usually adopted, where the upper walls of the first drainage channel 330 and the second drainage channel 332 are inclined upward and then the inner upper surfaces thereof are inclined upward, so that the path length of sewage to climb is shortened, the tortuosity of the climbing surface is also reduced, and the sewage climbing efficiency is further improved.

In one embodiment, the inclination angle α ranges from greater than 0 ° to less than 45 °. In another embodiment, the inclination angle α ranges from greater than 0 ° to less than 30 °.

In the embodiment shown in fig. 3, the inner upper surface 385 of the first drainage channel 330 has an inclination angle α 1 with the working surface, and the inner upper surface 381 of the second drainage channel 332 has an inclination angle α 2 with the working surface. Wherein the inclination angle α 1 and the inclination angle α 2 have the same value range as the inclination angle α in the above embodiment. The values of the inclination angle α 1 and the inclination angle α 2 may be the same or different. That is, the inclination angle α 1 may be equal to α 2, and the inclination angle α 1 may be larger or smaller than the inclination angle α 2.

It can be understood that the water flow climbing on the inner upper surfaces of the first drainage channel 330 and the second drainage channel 332 flows towards the dirt suction port 380, in order to inhibit the water flow on the inner upper surfaces of the first drainage channel 330 and the second drainage channel 332 from accumulating at the dirt suction port 380, and therefore, the water flow recovery efficiency is low. In one embodiment, the inclination angle α 1 is set to be unequal to α 2, so that the direction of the climbing water flow along the inner upper surfaces of the first diversion channel 330 and the second diversion channel 332 is not uniform, the effect of water flow accumulation is reduced, and the sewage recovery efficiency is ensured.

Further, the side walls of the soil suction port 380 are disposed obliquely, i.e., the side walls defining the soil suction port 380 are not perpendicular to the work surface. The non-vertical arrangement mode enables the sewage to be supported by the inner surface of the sewage suction port 380 in the climbing process, and the climbing efficiency of the sewage along with the airflow is improved. Specifically, the side wall of the soil suction port 380 extends obliquely upward in the direction of the second roll brush 382. Further, the inclination angle α 1 is set to be smaller than the inclination angle α 2, and the sewage climbing of the first drainage channel 330 and the second drainage channel 332 is balanced in cooperation with the side wall of the sewage suction port 380.

In another embodiment, referring to fig. 4, the inside upper surface 385 of the first drainage channel 330 adjacent to the suction port 380 has a drop height h with the inside upper surface 381 of the second drainage channel 332 adjacent to the suction port 380. In other words, the height of the inside upper surface 385, at which the first drainage channel 330 adjoins the suction port 380, is different from the height of the inside upper surface 381, at which the second drainage channel 332 adjoins the suction port 380. Here, "height" refers to the height from the working surface of the floor brush assembly 30. Wherein the fall h ranges from 5mm to 10 mm. With the adjacent inboard upper surface of first drainage channel 330 and soil pick-up mouth 380 and the adjacent inboard upper surface height difference setting of second drainage channel 332 and soil pick-up mouth 380, avoided under the highly the same condition, sewage is in soil pick-up mouth 380 department and is collided mutually, leads to sewage recovery to be obstructed, reduces sewage recovery efficiency.

In the embodiment shown in fig. 4, along the sewage recovery direction, the first drainage channel 330 and the second drainage channel 332 both extend obliquely upward, the portion close to the sewage suction port 380 is an upper end edge, and the upper end edge of the first drainage channel 330 is lower than the upper end edge of the second drainage channel 332, so that the upper surface of the inner side of the first drainage channel 330 close to the sewage suction port 380 is higher than the upper surface of the inner side of the first drainage channel 330 far away from the sewage suction port 380, and the upper surface of the inner side of the second drainage channel 332 close to the sewage suction port 380 is higher than the upper surface of the inner side of the second drainage channel 332 far away from the sewage suction port 380. Thus, the first drainage channel 330 and the second drainage channel 332 are inclined upwards towards the sewage suction port 380, and the sewage climbing difficulty is reduced.

Further, the side wall of the soil suction port 380 extends obliquely upward toward the second roll brush 382, and the height of the upper surface of the second drain passage 332 is set to be greater than that of the first drain passage 330. Specifically, the inner upper surface of the first drainage channel 330 adjacent to the dirt suction port 380 is 5mm to 10mm lower than the inner upper surface of the second drainage channel 332 adjacent to the dirt suction port 380, that is, the fall h ranges from 5mm to 10 mm. Therefore, the transition between the second drainage channel 332 and the side wall of the backward inclined sewage suction port 380 tends to be smooth, and the climbing difficulty of the sewage at the connection position is reduced.

In this embodiment, the first rolling brush 341 is adjacent to the front suction port of the first drainage channel 330, and the second rolling brush 342 is adjacent to the rear suction port of the second drainage channel 332, so that the sewage at the contact position of the rolling brush and the ground can be sucked and recovered as soon as possible, the sewage recovery efficiency is improved, and the cleaning effect is ensured. In order to secure the sewage suction efficiency, further, the other end of the first drainage channel 330 faces a portion of the outer surface below the axis of the first round brush 341, and the other end of the second drainage channel 332 faces a portion of the outer surface below the axis of the second round brush 342. The position is adjacent to the position where the rolling brush contacts with the ground, sewage is generated and gathered at the position, and the first drainage channel 330 and the second drainage channel 332 can timely recover the sewage.

In a specific embodiment, the projection of the first flow guiding channel 330 on the working surface of the floor brush assembly 30 has an overlapping portion with the projection of the first rolling brush 341 on the working surface, and correspondingly, the projection of the second flow guiding channel 332 on the working surface of the floor brush assembly 30 has an overlapping portion with the projection of the second rolling brush 342 on the working surface. So that the first drainage channel 330 is adjacent to the first rolling brush 341, the second drainage channel 332 and the second rolling brush 342, ensuring high sewage recovery efficiency.

In one embodiment, the rotation directions of the first rolling brush 341 and the second rolling brush 342 are set to be opposite, and with the state of the floor washing machine shown in fig. 3 as a reference, the first rolling brush 341 is set to rotate counterclockwise, and the second rolling brush 342 rotates clockwise, and in the case where the first rolling brush 341 and the second rolling brush 342 are driven to rotate, the linear velocity direction of the ground contact position of the first rolling brush 341 is directed to the first drainage channel 330 side, and the linear velocity direction of the work surface contact position of the second rolling brush 342 is directed to the second drainage channel 332 side. Therefore, along with the moving direction of the sewage driven by the rotation of the rolling brush, the sewage can move towards the corresponding suction opening direction under the inertia effect, the sewage recovery efficiency is improved, and the cleaning effect is ensured.

It can be understood that the water cleaning container 50 can provide clean water for mopping the floor, the clean water is sprayed onto the roller brush with fluff through the built-in clean water supply pipeline, the roller brush rotates at high speed to mop the floor, then the sewage after the second roller brush mops the floor enters the pipeline through the suction ports arranged in front and at the back of the floor brush assembly 30, the motor provides power, negative pressure and air flow are formed in the first and second drainage channels 330, 332 and the sewage discharge pipeline 13, the water in the first and second drainage channels 330, 332 and the sewage discharge pipeline 13 is driven to enter the sewage recovery barrel 40, and the processes of washing, mopping and sucking are completed. However, the sewage pipe 13 must have a certain length, and when the sewage enters the sewage recovery barrel 40 through the first drainage channel 330, the second drainage channel 332 and the sewage pipe 13, the sewage must exist in each section of the sewage pipe continuously, when the user completes one work, when the floor washing machine is turned off, since the suction assembly 20 stops working, the speed of the water flow in the sewage pipe 13 is slower than the speed of the air flow, at this time, a small amount of sewage is inevitably remained in the sewage pipe 13 and is not completely recovered, when the suction assembly 20 stops working, the sewage flows to the ground under the action of gravity, the flowing sewage drops on the ground, the ground is polluted again, the user needs to adopt other means to clean, and the use experience is very bad.

In order to solve the above problem, in a floor washing machine according to an embodiment of the present invention, referring to fig. 3 and 4, a backflow preventing groove 382 is disposed below the suction port 380, and the backflow preventing groove 382 forms a water storage cavity for temporarily storing sewage flowing down from the suction port 380 after the suction assembly 20 stops operating. Because the sewage suction port 380 is communicated with the lower end of the sewage discharge pipeline 13, when the suction assembly 20 stops working, sewage in the pipeline flows to the ground under the action of gravity, flows to the anti-backflow groove 382 below and is temporarily stored in the water storage concave cavity, so that the sewage cannot flow to the ground, and the trouble of secondary cleaning is avoided.

To ensure that the dirt does not drip outside the scope of the anti-drainback groove, the anti-drainback groove 382 is positioned such that its projection onto the working surface of the floor brush assembly 30 covers the projection of the opening of the dirt suction port 380 onto the working surface. That is, the projection of the opening of the soil suction port 380 on the working surface of the floor brush assembly 30 falls within the range of the projection of the backflow prevention groove 382 on the working surface. Further, the water storage cavity is arranged such that the projection of the opening of the dirt suction port 380 on the working surface of the floor brush assembly 30 covers the projection of the opening of the dirt suction port 380 on the working surface, and the projection of the opening of the dirt suction port 380 on the working surface falls within the range of the projection of the water storage cavity on the working surface.

In one embodiment, referring to fig. 4, the anti-backflow groove 382 is configured to be lower than the lower surface of the first drainage channel 330 adjacent to the second drainage channel 332. So, prevent that backward flow groove 382 is sunken to being less than the adjacent lower surface of first drainage channel 330 and second drainage channel 332, and sewage is stored in the water storage cavity under the action of gravity, as long as the volume of water storage cavity sets up rationally, can reduce sewage overflow to first drainage channel and second drainage channel's lower surface on, flow out to ground and cause the risk of pollution.

In one embodiment, referring to fig. 5, the floor brush assembly 30 further includes a liquid pump for pumping the water in the cleaning water container 50 and pressurizing the water and delivering the pressurized water to the water spray plate, from which the cleaning water is sprayed to substantially act on the corresponding roll brush surface. Because the floor cleaning machine 100 provided by the embodiment is provided with the two rolling brushes, the water adding amount of the two rolling brushes can be flexibly controlled, and the cleaning efficiency is improved. Further, the number of the liquid pumps is two, and the two liquid pumps include a first liquid pump 31 and a second liquid pump 32, wherein the water inlet ends of the first liquid pump 31 and the second liquid pump 32 are both communicated with the water cleaning container 50, the water outlet end of the first liquid pump 31 is communicated with the front water spraying plate 361, the water outlet end of the second liquid pump 32 is communicated with the rear water spraying plate 362, the first liquid pump 31 is used for sucking the water in the water cleaning container and spraying the pressurized water to the first rolling brush 341 through the front water spraying plate 361, and the second liquid pump 32 is used for sucking the water in the water cleaning container 50 and spraying the pressurized water to the second rolling brush 342 through the rear water spraying plate 362.

The scrubber 100 further includes a control panel (not shown) for controlling the operating frequency of the first and second liquid pumps 31 and 32, respectively, to adjust the watering flow rates of the front and rear water spray plates 361 and 362, respectively, to control the watering amounts of the first and second roll brushes 341 and 342. Because the water adding of the first rolling brush 341 and the second rolling brush 342 is controlled by the first liquid pump 31 and the second liquid pump 32 respectively, the water adding of the two rolling brushes is more flexibly controlled, and the control is convenient and effective, thereby ensuring the mopping effect of the floor washing machine.

Referring to fig. 3, the first liquid pump 31 and the second liquid pump 32 are respectively disposed on the left and right sides of the housing 37. Specifically, the first liquid pump 31 is disposed on the right side of the casing 37, and the second liquid pump 32 is disposed on the left side of the casing 37, that is, one liquid pump is disposed on each of the left and right sides of the casing 37, and the arrangement of the two liquid pumps in the floor brush assembly 30 is reasonable, which is beneficial to the volume uniformity and miniaturization of the floor brush assembly 30. The positions of the first liquid pump 31 and the second liquid pump 32 may be interchanged, the first liquid pump 31 may communicate with the rear water jet plate 362, and the second liquid pump 32 may communicate with the front water jet plate 361, which is not limited herein. The terms "left" and "right" refer to the directions of the arrows shown in fig. 3 as "front" directions, the left side of the body as left, and the right side as right, respectively, when the user operates the floor washing machine 100. In the embodiments of the present application, the terms "upper", "lower", "front", "rear", "left", "right", and the like are used with reference to the state of the floor washing machine shown in fig. 1, and the above description is only for illustrative purposes and should not be construed as limiting the present application.

The first liquid pump 31 and the second liquid pump 32 are both located between the first rolling brush 341 and the second rolling brush 342. Because the first rolling brush 341 and the second rolling brush 342 have a gap therebetween, an existing installation space is formed, and the first liquid pump 31 and the second liquid pump 32 are both disposed in the gap, which has less influence on the volume of the floor brush assembly 30, so that the floor brush assembly 30 is more compact and smaller.

Specifically, the first liquid pump 31 and the second liquid pump 32 are disposed in the housing 37 and are symmetrical to each other, so that the mass distribution of the floor brush assembly 30 is balanced, and the floor brush assembly is not exposed, and the appearance of the floor brush assembly is more beautiful.

In this embodiment, continuing to refer to FIG. 5, the scrubber assembly includes a three-way valve 35, the three-way valve 35 including a first port, a second port, and a third port. Wherein, the first port is communicated with the water cleaning container 50 through the first water inlet pipe 391, the second port is communicated with the water inlet end of the first liquid pump 31 through the second water inlet pipe 392, and the third port is communicated with the water inlet end of the second liquid pump 32 through the third water inlet pipe 393. The first liquid pump 31 communicates with the front spray plate 361 through a first outlet pipe 394, and the second liquid pump 32 communicates with the rear spray plate 362 through a second outlet pipe 395. The first water inlet pipe 391 may also be directly connected to the clean water container 50, that is, as a part of the clean water supply pipeline, connected between the three-way valve 35 and the clean water container 50.

The above is only one embodiment of the present invention, and any other modifications based on the concept of the present invention are considered as the protection scope of the present invention.
