Description

Technical Field

[0001] The utility model relates to the technical field of purification filters, and specifically, to a purification filter for a wall-climbing robot. Background Art

[0002] With the rapid development of modern urbanization, high-rise buildings have emerged in large numbers. The cleaning of the outer walls of these buildings has become an important and thorny problem. The traditional manual cleaning method is not only inefficient but also poses extremely high safety risks. Therefore, the emergence of wall-climbing robots provides a new idea for solving this problem. A wall-climbing robot is an intelligent robot specifically designed for cleaning the outer walls of high-rise buildings. It uses advanced adsorption technology and motion control algorithms to stably adsorb and autonomously walk on various complex walls. At the same time, it is equipped with an efficient cleaning system to clean the wall comprehensively and without dead corners. This kind of robot not only improves the cleaning efficiency but also significantly reduces the safety risks brought by manual cleaning.

[0003] There are some drawbacks in the existing devices during use. For example, the existing wall-climbing robots suck away the residues (water, water mist, sediment, dust, etc.) on the wall after cleaning. During sewage filtration, the filter element is easily blocked, resulting in the need to frequently clean and replace the filter element, shortening the service life of the filter element, increasing the workload and working time. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a purification filter for a wall-climbing robot to solve the problem that the existing wall-climbing robot sucks away the residues (water, water mist, sediment, dust, etc.) on the wall after cleaning and the filter element is easily blocked during sewage filtration.

[0005] The utility model provides the following technical solution: A purification filter for a wall-climbing robot, including a housing. A trapezoidal wall plate is fixedly connected to the inner bottom wall of the housing. Arc-shaped wall plates are fixedly connected to the outer walls of the two opposite sides of the trapezoidal wall plate, and the two arc-shaped wall plates are symmetrically arranged. An inner cavity and an outer cavity are formed inside the housing through the trapezoidal wall plate and the arc-shaped wall plates. An anti-backflow component is arranged on the housing.

[0006] In the above solution, through the ingenious setting of the trapezoidal wall plate and the arc-shaped wall plates inside the housing, two independent areas, namely the inner cavity and the outer cavity, are formed, thereby improving the purification efficiency. The anti-backflow component effectively prevents the filtered fluid from flowing back to the unpurified area through the inlet.

[0007] As a preference of the above technical solution, an inlet is opened on one outer wall of the housing, and the inlet is communicated with the inner cavity.

[0008] In the above solution, the design of the inlet enables the fluid to smoothly enter the inner cavity of the housing, which helps to ensure that the fluid is fully filtered inside the filter element, thereby improving the filtration efficiency.

[0009] Preferably, as an above - mentioned technical solution, the side of the trapezoidal wall panel away from the inlet is set as an inclined surface.

[0010] In the above - mentioned solution, the existence of the inclined surface increases the contact area and time between the fluid and the filter element material. During the flow of the fluid, it will continuously collide with the inner cavity of the trapezoidal wall panel, which helps to effectively remove impurities, particulate matters, etc. in the fluid, and further enhances the filtering effect of the filter element.

[0011] Preferably, as an above - mentioned technical solution, a sewage discharge port is opened at the position of the inclined surface of the trapezoidal wall panel on the lower end face of the housing, and the sewage discharge port is communicated with the inner cavity.

[0012] In the above - mentioned solution, the sewage discharge port enables the separated water and sediment to be discharged through the sewage discharge port.

[0013] Preferably, as an above - mentioned technical solution, an air outlet is opened on the upper end face of the housing, and the air outlet is communicated with the outer cavity.

[0014] In the above - mentioned solution, the air outlet ensures that the separated pure gas is smoothly discharged through the air outlet.

[0015] Preferably, as an above - mentioned technical solution, a plurality of communication grooves are arrayed on the outer walls of the opposite sides of the trapezoidal wall panel, and the inner cavity is communicated with the outer cavity through the communication grooves.

[0016] In the above - mentioned solution, the communication grooves form a plurality of fluid channels between the inner cavity and the outer cavity. When the fluid enters the inner cavity from the inlet, it will flow into the outer cavity through these communication grooves.

[0017] Preferably, as an above - mentioned technical solution, four mounting holes are arrayed in a rectangular pattern on the lower end face of the housing.

[0018] In the above - mentioned solution, the design of the four mounting holes enables the housing to be conveniently installed at a specified position.

[0019] Preferably, as an above - mentioned technical solution, the anti - backflow assembly includes mounting blocks symmetrically and fixedly connected to the inner wall of one side of the housing. A rotating shaft is rotatably connected between the two mounting blocks, and a sealing cover is fixedly connected to the outer wall of one side of the rotating shaft. The sealing cover is used to block the inlet.

[0020] In the above - mentioned solution, when the housing stops filtering the fluid, the sealing cover can block the inlet, effectively preventing the backflow phenomenon of the fluid flowing out through the inlet.

[0021] Preferably, as an above - mentioned technical solution, a torsion spring is arranged outside the rotating shaft.

[0022] In the above solution, when the outer shell stops filtering the fluid, the torsion spring can utilize its energy storage characteristic to automatically push the rotating shaft and the cover connected thereto to rotate, thereby blocking the inlet.

[0023] Compared with the prior art, the beneficial effects of the present utility model are:

[0024] In the present utility model, after the sewage enters the inner cavity of the filter element, due to the design of the trapezoidal wall plate, the sewage is preliminarily separated when hitting the inner cavity wall. The heavier sediment particles are deposited at the bottom of the inner cavity, while the lighter water continues to flow. This design improves the contact area between the sewage and the filter element and the separation efficiency. The rapid wind enters the outer cavity through the communication grooves on the trapezoidal wall plate and impacts the inner and outer cavity walls after turning through the arc-shaped wall plate, slowing down the rapid wind, thereby realizing the secondary separation of the sewage. This design further improves the separation efficiency of fine particles in the sewage and reduces the risk of filter element blockage. Through the above-mentioned primary separation and secondary separation processes, most of the sediment and particles in the sewage are effectively separated, reducing the blockage and wear of the filter element, thereby prolonging the service life of the filter element.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0032] Embodiment

[0033] As Figures 1 - 5As shown in the figure, the utility model provides a technical solution: a purification filter element for a wall-climbing robot, including a housing 10. A trapezoidal wall plate 11 is fixedly connected to the inner bottom wall of the housing 10. Arc-shaped wall plates 12 are fixedly connected to the outer walls on the opposite sides of the trapezoidal wall plate 11, and the two arc-shaped wall plates 12 are symmetrically arranged. An inner cavity 13 and an outer cavity 14 are formed inside the housing 10 through the arrangement of the trapezoidal wall plate 11 and the arc-shaped wall plates 12. An anti-backflow component 8 is arranged on the housing 10. An inlet 20 is opened on one outer wall of the housing 10, and the inlet 20 communicates with the inner cavity 13. The side of the trapezoidal wall plate 11 away from the inlet 20 is set as an inclined surface. A sewage discharge port 40 is opened on the lower end surface of the housing 10 at the position of the inclined surface of the trapezoidal wall plate 11, and the sewage discharge port 40 communicates with the inner cavity 13. An air outlet 50 is opened on the upper end surface of the housing 10, and the air outlet 50 communicates with the outer cavity 14. A plurality of communication grooves 60 are arranged in an array on the outer walls on the opposite sides of the trapezoidal wall plate 11, and the inner cavity 13 communicates with the outer cavity 14 through the communication grooves 60. Four mounting holes 70 are arranged in a rectangular array on the lower end surface of the housing 10. In the specific use process, the housing 10 is installed at a specified position through the four mounting holes 70. After the installation is completed, the dust suction motor of the wall-climbing robot starts to work, sucking the sewage on the wall into the purification filter element. The sewage enters the inner cavity 13 through the inlet 20 on one side of the housing 10. The sewage impacts the inner wall of the inner cavity 13 on the inner side of the trapezoidal wall plate 11. Since the side of the trapezoidal wall plate 11 away from the inlet 20 is set as an inclined surface, after the impact, the water and sediment will be initially separated due to inertia. The heavier sediment particles will settle at the bottom of the inner cavity 13, while the lighter water will continue to flow. As the sewage continues to flow, the rapid air enters the outer cavity 14 through the communication grooves 60 on the trapezoidal wall plate 11, turns through the arc-shaped wall plate 12 and impacts the inner and outer cavity walls of the outer cavity 14, and the rapid air slows down for secondary separation. The purified gas after the secondary separation is discharged through the air outlet 50 at the upper end of the housing 10, and the separated gas will not pollute the environment. The separated water and sediment enter the collector through the sewage discharge port 40, which is convenient for the water to be further purified and reused, enhancing the service life of the water purification filter element, increasing the time for purifying water, improving the working efficiency of the robot, and the anti-backflow component 8 prevents the filtered fluid from flowing back to the unpurified area through the inlet 20.

[0034] As an implementation manner in this embodiment, as Figure 2 and Figure 4As shown in the figure, the anti-backflow component 8 includes mounting blocks 801 symmetrically and fixedly connected to the inner wall of one side of the housing 10. A rotating shaft 802 is rotatably connected between the two mounting blocks 801. A sealing cover 803 is fixedly connected to the outer wall of one side of the rotating shaft 802. The sealing cover 803 is used to block the inlet 20. A torsion spring 90 is arranged outside the rotating shaft 802. In the specific use process, when the dust suction motor works, it will generate negative pressure at the inlet 20 of the housing 10. Since the sealing cover 803 blocks the inlet 20 of the housing 10, the negative pressure generated by the dust suction motor will directly act on the sealing cover 803. The negative pressure will cause the sealing cover 803 to receive an inward pulling force, and this pulling force will cause the sealing cover 803 to rotate around the rotating shaft 802, thereby opening the inlet 20. When the negative pressure acts on the sealing cover 803 and opens it, the torsion spring 90 will be stretched and store energy. Once the dust suction motor stops working and the negative pressure disappears, the torsion spring 90 will release the stored energy, causing the sealing cover 803 to automatically return to its original position and block the inlet 20.

[0035] Working principle: When the dust suction motor of the wall-climbing robot starts to work, it will generate negative pressure at the inlet 20 of the housing 10. Since the sealing cover 803 blocks the inlet 20 of the housing 10, the negative pressure generated by the dust suction motor will directly act on the sealing cover 803. The negative pressure will cause the sealing cover 803 to receive an inward pulling force, and this pulling force will cause the sealing cover 803 to rotate around the rotating shaft 802, thereby opening the inlet 20. When the negative pressure acts on the sealing cover 803 and opens it, the torsion spring 90 will be stretched and store energy. Sewage enters the inner cavity 13 through the inlet 20 on one side of the housing 10. The sewage impacts the inner wall of the inner cavity 13 of the trapezoidal wall plate 11. Since the side of the trapezoidal wall plate 11 away from the inlet 20 is set as an inclined surface, after the sewage impacts, the water and sediment will be initially separated due to inertia. The heavier sediment particles will settle at the bottom of the inner cavity 13, while the lighter water will continue to flow. As the sewage continues to flow, the rapid air enters the outer cavity 14 through the communication groove 60 on the trapezoidal wall plate 11, turns through the arc-shaped wall plate 12 and impacts the inner and outer cavity walls of the outer cavity 14. The rapid air slows down and undergoes secondary separation. The purified gas after secondary separation is discharged through the air outlet 50 at the upper end of the housing 10. The separated gas will not pollute the environment. The separated water and sediment enter the collector through the sewage outlet 40, which is convenient for further purification and reuse of the water. When the wall cleaning task is completed, the dust suction motor is turned off, the negative pressure disappears, and the torsion spring 90 will release the stored energy, causing the sealing cover 803 to automatically return to its original position and block the inlet 20.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
