Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a water-air separation device and a cleaning robot. Background Technology

[0002] With the development of modern cities, skyscrapers are rising one after another, and the cleaning of glass curtain walls of high-rise buildings is becoming increasingly important. The traditional cleaning method involves manual high-altitude cleaning, which is extremely dangerous. To replace the traditional method of cleaning high-rise curtain walls, high-altitude planar curtain wall cleaning robots have emerged as an alternative.

[0003] During the cleaning process, wastewater flows out after the cleaning robot finishes cleaning. If the wastewater is discharged directly, the cleaned parts of the curtain wall will be contaminated again by the discharged wastewater. Therefore, the wastewater needs to be recycled back into the cleaning robot. However, since the cleaning robot uses a negative pressure fan, a large amount of gas will enter the wastewater, so the gas in the wastewater also needs to be discharged. Therefore, designing a water-gas separation device suitable for wastewater recycling is an urgent technical problem to be solved. Summary of the Invention

[0004] This invention provides a water-air separation device and a cleaning robot to solve the technical problem of unsatisfactory water-air separation effect in the wastewater recycling of existing cleaning robots, thereby achieving the purpose of smooth recycling of curtain wall cleaning wastewater and improving water-saving effect.

[0037] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] The following is combined with Figures 1-7 This invention describes a water-air separation device 100 and a cleaning robot according to an embodiment of the present invention. It should be noted that the cleaning robot can be used to clean glass curtain walls or household windows. The cleaning robot adheres to the surface to be cleaned and performs cleaning on the surface.

[0039] During the cleaning process, wastewater will flow out after the cleaning robot cleans. If the wastewater is discharged directly, the cleaned part of the curtain wall will be contaminated again by the discharged wastewater. Therefore, the wastewater needs to be recycled into the water-gas separator 100. At the same time, the water-gas separator 100 discharges the gas in the wastewater to maintain the continuity of wastewater recycling and water-gas separation.

[0040] Combination Figure 1 and Figure 2 As shown, the water-air separation device 100 according to an embodiment of the present invention includes: a housing 110 and a wind-driven component 200. The housing 110 has a drain port 145 and includes a first wall 120, a second wall 130, and a peripheral wall 140. The drain port 145 can be located at the connection between the peripheral wall 140 and the second wall 130. The housing 110 can be cylindrical or cuboid in shape; however, the shape of the housing 110 is not limited to these shapes, and no specific limitation is made here.

[0041] The first wall 120 and the second wall 130 are spaced apart, and the peripheral wall 140 is sandwiched between the first wall 120 and the second wall 130. The first wall 120, the second wall 130, and the peripheral wall 140 define a receiving cavity 141. The first wall 120 or the peripheral wall 140 is provided with an exhaust port 122, and the second wall 130 is provided with a water inlet 131. The water-air mixture flows into the water-air separator 100 through the water inlet 131, and water-air separation occurs in the receiving cavity 141. The liquid portion can be discharged from the drain port 145, and the gas portion can be discharged from the exhaust port 122.

[0042] A wind-driven component 200 is rotatably disposed within the receiving cavity 141. The wind-driven component 200 is connected to the inlet 131 and is used to draw sewage into the receiving cavity 141 through the inlet 131. After the water-air mixture enters the receiving cavity 141 through the inlet 131, it flows within the receiving cavity 141 under the drive of the wind-driven component 200. At this time, under the action of gravity, the liquid sinks to the bottom of the receiving cavity 141 and can be discharged through the drain port 145. The gas is discharged from the exhaust port 122 under the positive pressure driven by the wind-driven component 200.

[0043] It should be noted that the water-air mixture enters the air-driven component 200 from the inlet 131 in an axial direction (flowing towards the first wall 120 is axial), and after exiting the air-driven component 200, the flow direction changes to radial (flowing towards the peripheral wall 140 is radial). Since the radial movement distance of the fluid in the receiving cavity 141 is greater than the axial distance, this increases the flow distance of the water-air mixture within the receiving cavity 141, which is beneficial for the liquid portion of the fluid to deposit at the bottom of the receiving cavity 141, while the gas portion flows towards the exhaust port 122, thereby improving the water-air separation efficiency.

[0044] Meanwhile, the wind-driven component 200 is rotatable. During the rotation of the wind-driven component 200, a negative pressure is formed at the water inlet 131 in the receiving cavity 141, causing the fluid to continuously flow into the receiving cavity from the water inlet 131. The separated gas in the receiving cavity 141 also flows to the exhaust port 122 under the rotation of the wind-driven component 200, thereby improving the water-gas separation efficiency of the water-gas separation device 100 and improving the continuity of water-gas separation in the water-gas separation device 100.

[0045] Understandably, the water-air mixture continuously enters the receiving cavity 141 from the inlet 131 under the rotation of the wind-driven component 200. At the same time, under the action of the wind-driven component 200, the fluid flows radially. Due to gravity, the liquid either settles in the receiving cavity 141 or is discharged from the drain port 145. Under the action of the wind-driven component 200, the gas flows to the exhaust port 122 and is discharged from the water-air separator 100. Thus, the water-air separator 100 achieves water-air separation.

[0046] According to an embodiment of the present invention, the water-gas separation device 100 provides a wind-driven component 200 inside the housing 110. The water-gas mixture continuously enters the housing 110. The liquid separates from the gas due to gravity and is deposited at the bottom of the housing 110. The gas part moves toward the first wall 120 and is discharged from the exhaust port 122. This allows for sufficient separation of water and gas, thereby improving the water-gas separation effect of the water-gas separation device 100.

[0047] According to some embodiments of the present invention, a baffle 300 is located within the receiving cavity 141 and divides the receiving cavity 141 into a communicating first cavity 142 and a second cavity 143. A wind-driven component 200 is located on one side of the baffle 300, and an exhaust port 122 is located on the other side of the baffle 300. The baffle 300 can limit the flow path of the water-air mixture, prolonging the flow time of the water-air mixture, thereby allowing sufficient time for liquid and gas separation. Furthermore, the baffle 300 can also prevent the water-air mixture from impacting the receiving cavity 141 and prevent the water-air mixture from being directly discharged from the exhaust port 122. Therefore, by providing the baffle 300, water and gas can be sufficiently separated, thereby improving the water-air separation effect.

[0048] Specifically, the water-air mixture enters the first chamber 142 through the inlet 131. Then, the water-air mixture is immediately acted upon by the wind-driven component 200 and flows toward the peripheral wall 140. After being blocked by the baffle 300, it is deposited at the bottom of the shell 110 and flows into the second chamber 143. At this time, the gas portion of the fluid in the second chamber 143 moves toward the first wall 120 and is discharged from the exhaust port 122.

[0049] In some examples, the first wall 120 and the peripheral wall 140 are detachably connected, which facilitates the installation of the wind-driven component 200 into the housing 110 and also facilitates the removal of the wind-driven component 200. In addition, by making the first wall 120 and the peripheral wall 140 detachably connected, it is also convenient to clean and maintain the inside of the receiving cavity 141.

[0050] According to some embodiments of the present invention, in combination Figure 1 and Figure 2 As shown, multiple exhaust ports 122 and multiple drain ports 145 can be provided, which can increase the processing capacity of the water-air separation device 100, improve the efficiency of the water-air separation device 100, and enable the cleaning robot to work better. At the same time, by setting multiple exhaust ports 122 or multiple drain ports 145, the pipeline can be connected to the housing 110 from multiple directions, thereby allowing for better layout of the various components inside the cleaning robot.

[0051] According to some embodiments of the present invention, in combination Figure 2 , Figure 4 and Figure 5 As shown, the first wall 120 protrudes towards the interior of the receiving cavity 141 to form a mounting groove 123 on the outer surface of the first wall 120. The bottom wall of the mounting groove 123 forms a mounting position 121. The water-air separation device 100 also includes a motor 210, which is mounted in the mounting groove 123 and is used to drive the wind drive component 200. In some examples, the wind drive component 200 may be a centrifugal fan or a centrifugal impeller, adapted to be installed with the motor 210. Here, the wind drive component 200 is not specifically limited.

[0052] In some examples, the mounting slot 123 is also provided with a through hole to allow the rotating shaft of the motor 210 to pass through, preventing sewage from flowing out of the through hole and damaging the motor 210. The rotating shaft of the motor 210 is connected to the air drive component 200, which drives the air drive component 200 to rotate, causing the sewage to flow to the periphery of the baffle 300, reducing the impact force of the sewage on the baffle 300, and preventing the sewage from only impacting a part of the baffle 300, thus preventing excessive impact force on that part of the baffle 300.

[0053] Here, the greater the power of the motor 210 and the faster the rotation speed of the wind drive component 200, the greater the negative pressure generated at the fluid inlet of the wind drive component 200 and the greater the positive pressure provided to the containment cavity 141. As a result, the gas in the sewage can escape from the sewage more quickly, which is beneficial to achieving water-gas separation.

[0054] According to some embodiments of the present invention, in combination Figures 2-5 As shown, the mounting slot 123 is also provided with a plurality of mounting parts 127, which can be used to fix the motor 210 in the mounting slot 123. The fixing method of the mounting parts 127 can be threaded connection and / or snap-fit ​​connection. In some examples, taking the motor 210 as a threaded connection as an example, the motor 210 is provided with threaded holes, and screws fix the motor 210 in the mounting slot 123 through the mounting holes.

[0055] According to some embodiments of the present invention, in combination Figure 2 As shown, the second wall 130 protrudes towards the interior of the receiving cavity 141 to form a protrusion 132. A water inlet 131 is located on the protrusion 132, which is opposite to the mounting position 121. The air-driven component 200 is located between the protrusion 132 and the mounting position 121. The inner surface of the peripheral wall 140 and the inner surface of the second wall 130 on the side of the protrusion 132 defines a wastewater tank 144. The wastewater tank 144 increases the wastewater storage capacity of the housing 110. The protrusion 132 is at a certain height from the bottom of the housing 110 to prevent wastewater in the wastewater tank 144 from being discharged from the water inlet 131, thus affecting the water-air separation efficiency.

[0056] According to some embodiments of the present invention, in combination Figure 2 and Figure 3 As shown, the protrusion 132 extends into a positioning groove 126, which better fixes the wind-driven component 200 on the mounting position 121, so that it can be stably fixed on the mounting position 121 of the protrusion 132 even under the impact of sewage negative pressure, and prevents the wind-driven component 200 from shifting.

[0057] According to some embodiments of the present invention, in combination Figure 2 and Figure 3As shown, the baffle 300 is integrally formed with the first wall 120, and the free end of the baffle 300 is spaced apart from the second wall 130. The free end of the baffle 300 is spaced a certain distance from the second wall 130, so that the fluid can be blocked by the baffle 300, while still flowing from the first cavity 142 to the second cavity 143 for water-air separation.

[0058] According to some embodiments of the present invention, in combination Figure 4 and Figure 5 As shown, there is one baffle 300 in an annular shape, surrounding the outer periphery of the wind-driven component 200; or there are multiple baffles 300 spaced apart along the circumferential direction of the wind-driven component 200. The baffles 300 have a certain slope on the side of the first cavity 142 to guide sewage to deposit in the sewage tank 144. Here, the shape of the baffles 300 is not specifically limited, as long as it can block the sewage guided by the wind-driven component 200 and cause it to deposit towards the bottom of the housing 110.

[0059] In some examples, taking the baffle 300 as an annular shape as an example, such as Figure 5 As shown, the baffle 300 is provided with a plurality of reinforcing ribs 301, which are connected between the first wall 120 and the baffle 300 to enhance the structural reliability of the baffle 300.

[0060] According to some embodiments of the present invention, in combination Figure 4 and Figure 5 As shown, the first wall 120 is provided with an anti-overflow baffle 124, which is located inside the receiving cavity 141 and surrounds the exhaust port 122. It can be understood that the cleaning robot is not limited to vertical movement during the curtain wall cleaning process, but also needs to work at other working angles. Therefore, the water-air separation device 100 also needs to be able to work at other working angles. Therefore, the anti-overflow baffle 300 surrounding the exhaust port 122 can prevent liquid from being discharged from the exhaust port 122 when it is working at other working angles.

[0061] It is understandable that the anti-overflow baffle 124 and the surrounding wall 140 are spaced at a certain distance to form a special water storage space. When the cleaning robot is working in a vertical position, there may be a problem that the sewage discharge efficiency of the drain 145 is limited. At this time, the sewage can be deposited in the water storage space, thereby being buffered and preventing liquid from being discharged from the exhaust port 122.

[0062] According to some embodiments of the present invention, in combination Figure 4 and Figure 5As shown, the first wall 120 is provided with a thickened portion 128, the thickness of which is greater than the thickness of the rest of the first wall 120. The thickened portion 128 has an exhaust channel extending along its thickness direction, and the exhaust channel is connected to the exhaust port 122. The thickened portion 128 is connected to the reinforcing rib 301 and is located between the baffle 300 and the first wall 120, improving the structural stability of the baffle 300 and the first wall 120.

[0063] According to some embodiments of the present invention, in combination Figure 4 and Figure 5 As shown, the exhaust channel is equipped with multiple sound-absorbing fins 125. The multiple sound-absorbing fins 125 have the same structure, and the angle between the sound-absorbing fins 125 and the exhaust port 122 is acute, so as to guide the liquid splashed into the exhaust channel back into the receiving cavity 141, thereby depositing it into the sewage tank 144, and at the same time reducing the speed of gas discharged from the exhaust port 122, thereby achieving the purpose of noise reduction.

[0064] According to some embodiments of the present invention, in combination Figure 6 and Figure 7 As shown, the outer surface of the housing 110 is provided with at least one wire-holding groove. The wire-holding groove can be used to store the wire 211 of the motor 210, preventing the wire 211 from moving and being agitated by the moving parts inside the robot during the operation of the cleaning robot, thus preventing the wire 211 from breaking the circuit.

[0065] Here, the construction of the wire slot is not specifically limited. For example, in some embodiments, such as... Figure 6 As shown, the first wire-holding groove 400 extends from the first wall 120 of the housing 110 with two engaging portions 401 to secure the wire 211 within the first wire-holding groove 400; furthermore, in other embodiments, such as Figure 7 As shown, the first wall 120 of the housing 110 is recessed to form a second wire-holding groove 410 for placing and fixing the wire 211.

[0066] The cleaning robot according to an embodiment of the present invention includes the water-air separation device 100 as described above. The cleaning robot uses negative pressure to introduce wastewater from the inlet 131 into the water-air separation device 100 for water-air separation.

[0067] The flow process of fluid entering the water-gas separator 100 is described below:

[0068] Fluid enters the first cavity 142 within the housing 110 through inlet 131. Driven by the wind-driven component 200, it flies out towards the peripheral wall 140 and is then blocked by the baffle 300, flowing towards the wastewater tank 144 for deposition. At this point, water and gas separation occurs in the second cavity 143. The liquid portion settles in the wastewater tank 144 due to gravity, while the gaseous portion rises through the exhaust channel and is discharged from the exhaust port 122. Wastewater in the wastewater tank 144 can be discharged through the drain port 145.

[0069] According to the present invention, the cleaning robot provides a wind-driven component 200 inside the housing 110 and uses a baffle 300 to limit the flow path of the fluid. During the flow of the water-air mixture inside the housing 110, the liquid separates from the gas due to gravity and settles at the bottom of the housing 110, while the gas moves toward the first wall 120 and is discharged from the exhaust port 122. This allows for sufficient separation of water and gas, thereby improving the water-air separation effect of the water-air separation device 100.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
