DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the application more clear, the technical solutions in the application will be described clearly and completely in combination with the drawings in the application. Obviously, the described embodiments are some embodiments of the application, not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the application.

[0024] The traditional floor cleaning machine is difficult to clean low space, the main reason is that the sewage tank of the floor cleaning machine is easy to cause the sewage to enter the fan or other electronic components of the floor cleaning machine with air in the dumping case, resulting in the failure of the floor cleaning machine or affecting the service life of the floor cleaning machine.

[0025] Therefore, the application provides a sewage tank of a floor cleaning machine capable of preventing sewage from entering the machine body in a horizontal state, and a floor cleaning machine using the sewage tank. Figure 3 As shown in the figure, when facing the cleaning environment of low height such as the bottom of the bed, the machine body 202 can be laid down to work, so that the brush base 203 can enter these narrow environments for cleaning.

[0026] As shown in the figure, the sewage tank of the floor cleaning machine comprises a sewage chamber 110, and one end of a sewage suction pipe 120 is used for communicating with the brush base 203, and the other end extends into the sewage chamber 110. Figure 1 and Figure 2 During the working of the floor cleaning machine, the fan draws air from the sewage chamber 110 through the exhaust port 111, so that a negative pressure environment is formed in the sewage chamber 110, and then the sewage can be sucked in along the direction indicated by the thick arrow in the figure. Figure 2

[0027] The sewage suction pipe 120 is provided with a first sewage baffle 122 outside the water outlet 121 in the sewage chamber 110, as shown in the figure, a first stepped groove 123 and a second stepped groove 124 are formed between the first sewage baffle 122 and the sewage suction pipe 120. Figure 2 After the sewage flows out of the water outlet 121, it enters the first stepped groove 123 and the second stepped groove 124 based on inertia. The sewage entering the first stepped groove 123 can be guided along the first sewage baffle 122 to the opening of the first stepped groove 123 towards the sewage chamber 110, so that the sewage flows in the direction away from the exhaust port 111 of the sewage chamber 110, and the sewage in the second stepped groove 123 flows back after being blocked, and is mixed into the subsequent sewage, so as to reduce the impact force of the sewage flowing out of the water outlet 121.

[0028] During the use of the sewage tank, the height position of the exhaust port is always higher than that of the water outlet 121 and the first sewage baffle 122. Figure 1 As shown in the figure, the sewage intercepted by the first sewage baffle 122 is collected at the bottom of the sewage chamber 110 under the action of gravity, and the air is discharged through the exhaust port 111 at the top of the sewage chamber 110; in the horizontal state of the sewage tank, as shown in the figure, Figure 2 ​As shown, the sewage intercepted by the first sewage baffle 122 collects in the sewage chamber 110 below the suction pipe 120 under the action of gravity. The sewage is far away from the outlet 121 and the exhaust port 111, and the air can also be discharged smoothly through the exhaust port 111 at the top of the sewage chamber 110.

[0029] The exhaust port 111 is preferably provided with a second sewage baffle 112 and a flexible cover 114. An air channel is formed between the second sewage baffle 122 and the inner wall of the sewage chamber 110, and an L-shaped cavity 113 is formed between the air channel and the exhaust port 111 to reduce the flow rate of the fluid through a complex flow path, thereby further increasing the difficulty for water vapor to reach the exhaust port 111 with the flowing air.

[0030] like Figure 2 As shown, when the machine body is lying flat, due to the upward-facing opening of the L-shaped cavity 113 formed by the second sewage baffle 112 in the sewage chamber 110, and the effect of the flexible sealing cover 114, sewage is difficult to enter other parts of the floor scrubber body. When working flat, sewage is sucked into the sewage tank from the suction pipe 120 (e.g., Figure 2 (Medium-thick arrow) Under the action of the first sewage baffle 122 and gravity, sewage remains in the sewage tank, while air passes through the second sewage baffle 112 and the flexible cover 114, entering the machine body from the exhaust port 111 (e.g., Figure 2 (As indicated by the thin arrow). Throughout the process, wastewater will not enter the machine body, protecting the electronic components of the floor scrubber and increasing the machine's lifespan.

[0031] In addition, the flexible cover 114 can seal the exhaust port 111 when the fan is not running, based on its own elasticity, thereby preventing water in the sewage chamber 110 from evaporating and entering the machine body when the floor scrubber is in standby mode.

[0032] like Figure 3 As shown, when the floor brush base 203 is cleaning the bottom surface, the machine body 202 can undergo significant angular changes relative to the floor brush base 203. For example, the machine body 202 can operate perpendicular to the bottom surface, tilt relative to the bottom surface, or be parallel to the bottom surface. At different working angles of the machine body 202, the user can adjust the angle of the rotating handle 204 to a more comfortable operating position, thus enabling the floor scrubber to be used in more cleaning environments, such as cleaning low-ceilinged spaces. Based on the wastewater tank of the floor scrubber described above, even when operating at an angle parallel to the bottom surface, the machine body and its wastewater tank can effectively prevent wastewater from entering the electronic components of the machine body. This not only improves the floor scrubber's cleaning ability in low-ceilinged spaces but also enhances the safety of the floor scrubber's operation.

[0033] To better understand the above technical solutions, the various specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] According to the present invention, a wastewater tank for a floor scrubber includes a wastewater chamber 110 and a suction pipe 120 extending into the wastewater chamber 110. The wastewater chamber 110 includes an exhaust port 111, which is connected to a blower. During operation, the wastewater tank creates a negative pressure environment within the wastewater chamber 110 using the blower, thereby drawing wastewater from the outside through the suction pipe 120. The wastewater is contained within the wastewater chamber 110, while the incoming air is discharged through the exhaust port 111. To prevent water droplets or moisture from being discharged directly through the exhaust port 111 and affecting the electrical components of the floor scrubber, a first wastewater baffle 122 is preferably provided at the outlet 121 of the suction pipe 120 within the wastewater chamber 110. This first wastewater baffle 122 allows the fluid discharged from the outlet 121 to flow in a direction away from the exhaust port 111. The wastewater tank can be used in a normal state and a horizontal state. In the horizontal state, the suction pipe 120 is parallel to the ground. In both normal and horizontal states, the vent 111 is positioned higher than the outlet 121 and the first sewage baffle 122.

[0035] According to this design, the wastewater tank of the floor scrubber, through the first wastewater baffle 122, can block wastewater drawn into the wastewater chamber 110 by the blower, causing the wastewater to collect at the bottom of the wastewater chamber 110 (the lower position within the wastewater chamber 110 in the direction of gravity) under the influence of gravity. In both the normal and horizontal states, the exhaust port 111 is positioned higher than the water outlet 121 and the first wastewater baffle 122, thus ensuring that the wastewater is always kept away from the exhaust port 111 under the influence of gravity. With the first wastewater baffle 122 guiding the fluid discharged from the water outlet 121 away from the exhaust port 111, the gravity acting on the wastewater causes the air entering the wastewater chamber 110 to separate from the wastewater before flowing towards the exhaust port 111.

[0036] like Figure 3 As shown, the normal state of the present invention can be understood as the working state in which the body 202 of the floor scrubber is perpendicular to the ground or inclined relative to the ground during normal operation; the horizontal state can be understood as the working state in which the body 202 of the floor scrubber and the handle 201 fixed to the body 202 are parallel or nearly parallel to the ground when cleaning low spaces.

[0037] In a preferred embodiment, when the wastewater tank is positioned below the outlet 121 in both normal and horizontal states, a water level detector can be installed to monitor the water level in the wastewater chamber 110. When the water level reaches or exceeds the detector level, an alarm signal can be sent to the floor scrubber's control system to remind the user to clean the wastewater.

[0038] According to the wastewater tank of a floor scrubber provided by the present invention, based on the above-described scheme, the outlet 121 of the suction pipe 120 is preferably opened on the pipe wall of the suction pipe 120 near the exhaust port 111. In a horizontal state, the outlet 121 faces upward in the direction of gravity, and the wastewater in the wastewater chamber 110 collects in the wastewater chamber 110 below the outlet 121 under the action of gravity.

[0039] like Figure 2 As shown, when the sewage tank is in a horizontal state, sewage is sucked out from the outlet 121 of the suction pipe 120. Under the guidance of the first sewage baffle 122, the sewage moves in an oblique downward direction away from the exhaust port 111. Under the action of gravity, the sewage collects at the bottom of the sewage chamber 110 in a horizontal state, while the air is separated from the sewage during the movement.

[0040] According to the present invention, a wastewater tank for a floor scrubber has a first stepped groove 123 formed between a first wastewater baffle 122 and a suction pipe 120. When the blower is started, the fluid in the suction pipe 120 moves in a first direction. After the fluid discharged from the outlet 121 enters the first stepped groove 123, it is guided by the first stepped groove 123 to a second direction. The second direction is opposite to the first direction and faces away from the exhaust port 111.

[0041] In the vertical position of the sewage tank, such as Figure 1 As shown, the bottom of the sewage chamber 110 is located where the suction pipe 120 enters the sewage chamber 110. Under negative pressure, the first direction is from bottom to top, and the second direction points towards the bottom of the sewage chamber 110. The sewage can be guided to the bottom of the sewage chamber 110 via the first stepped groove 123. When the sewage tank is horizontal, the second direction is parallel to the horizontal plane and away from the exhaust port 111. After entering the first stepped groove 123, the sewage can also be guided to the position where the suction pipe 120 enters the sewage chamber 110. Under the action of gravity, it eventually bypasses the suction pipe 120 and collects in the sewage chamber 110 below the suction pipe 120. Similar to the above situation, the first stepped groove 123 can work with gravity to guide the sewage entering the sewage chamber 110 away from the exhaust port 111 as much as possible, and finally collect at a lower position in the direction of gravity of the sewage chamber 110. This ensures that the sewage in the sewage tank is always away from the exhaust port 111, reducing the risk of sewage entering the electronic components of the floor scrubber.

[0042] Furthermore, in the wastewater tank of a floor scrubber provided by the present invention, a second stepped groove 124 is formed between the first wastewater baffle 122 and the suction pipe 120; the second stepped groove 124 is adjacent to the outlet 121 and is located in the middle of the first stepped groove 123 and the outlet 121.

[0043] As Figure 2 shown, along the direction of the thick arrow, the sewage passing through the second stepped groove 124, a part of it enters the second stepped groove 124, encounters resistance and backflows into the subsequent sewage, thereby slowing down the flow inertia of the sewage, reducing the impact force, and further making the sewage more easily receive the guiding effect of the first sewage baffle 122 and the action of gravity and be left at the bottom of the sewage chamber 110.

[0044] According to the sewage tank of the floor cleaning machine provided by the present application, the second sewage baffle 112 is arranged at the exhaust port 111; the second sewage baffle 112 is formed with an L-shaped cavity 113 communicating with the exhaust port 111, and the opening of the L-shaped cavity 113 is close to the side wall of the sewage chamber 110.

[0045] During the separation process of air and sewage in the sewage chamber 110, part of the water that fails to be successfully separated will inevitably move with the air to the vicinity of the exhaust port 111. By arranging the second sewage baffle 112, the movement path of the air can be further increased by the L-shaped cavity 113, and the opening of the L-shaped cavity 113 is close to the side wall of the sewage chamber 110, which can further separate the sewage before the air enters the L-shaped cavity 113.

[0046] Preferably, according to the sewage tank of the floor cleaning machine provided by the present application, at least part of the side wall of the sewage chamber 110 is distributed around the second sewage baffle 112 to form an air channel communicating with the opening of the L-shaped cavity 113 between the side wall of the sewage chamber 110 and the second sewage baffle 112, thereby further improving the separation effect of the complex air flow path on the sewage. In addition, as Figure 1 and Figure 2 shown, the inner side wall of the sewage chamber 110 preferably forms an accommodation space with a farther distance from the axis of the suction pipe 120 around the second sewage baffle 112, so that the position of the exhaust port 111 and the opening of the L-shaped cavity 113 has a farther distance from the bottom of the sewage chamber 110 in the horizontal state of the sewage tank.

[0047] According to the sewage tank of the floor cleaning machine provided by the application, the air outlet 111 is provided with a flexible cover 114, the flexible cover 114 covers the outside of the air outlet 111, and only when air is discharged from the sewage chamber 110, the flowing air can push away the flexible cover 114. The flexible cover 114 can be closed to the air outlet 111 based on the elastic force of itself when the fan is not started, so that the moisture in the sewage chamber 110 can be prevented from evaporating and invading the machine body in the standby state of the floor cleaning machine. Moreover, in the process of pushing the flexible cover 114 to deform and open the air outlet 111, the flexible cover 114 always exerts resistance to the air based on the elastic force of itself, which is beneficial to the final separation of water vapor. In addition, in actual application, the air outlet 111 and the fan of the floor cleaning machine are further provided with a filter assembly with a water absorption or water filtering function, which can finally filter a small amount of moisture sucked out of the air outlet 111 with air.

[0048] The application further provides a floor cleaning machine, as shown in Figure 1 and Figure 3 , comprising a handle 201, a machine body 202 and a floor brush base 203, and the machine body 202 is provided with any one of the sewage tanks of the floor cleaning machine described above.

[0049] The first sewage baffle 122 can block the sewage sucked into the sewage chamber 110 by the fan, so that the sewage is collected at the bottom of the sewage chamber 110 under the action of gravity (a lower position in the sewage chamber 110 in the direction of gravity). According to the conventional state and the horizontal state, the position of the air outlet 111 is higher than that of the water outlet 121 and the first sewage baffle 122, so that the sewage can always be away from the air outlet 111 under the action of gravity. In the case that the first sewage baffle 122 guides the fluid discharged from the water outlet 121 to the direction away from the air outlet 111, the gravity of the sewage can separate the air entering the sewage chamber 110 from the sewage before flowing to the air outlet 111. Therefore, the floor cleaning machine using the sewage tank can also be used normally in the horizontal state, and the risk of sewage invading other parts of the floor cleaning machine can be reduced, so that the cleaning ability of the floor cleaning machine in low space is improved, and the risk of electronic components being invaded by sewage is reduced.

[0050] According to the scrubber provided by the application, the top end of the handle 201 is provided with a rotating handle 204 capable of rotating around the axis of the handle 201. The brush base 203 has a deflection freedom of at least 90 degrees relative to the machine body 202; the scrubber can be used in a normal state and a horizontal state, in the horizontal state, the machine body 202 and the brush base 203 are both parallel to the ground. The rotating handle 204 has at least a rotating position close to the side of the user in the normal state of the scrubber and a rotating position away from the bottom side in the horizontal state. In the horizontal state of the scrubber, the user can conveniently realize the cleaning work in a low space by rotating the upward handle based on the total length of the handle 201 and the machine body 202.

[0051] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
