Description

Technical Field

[0001] The utility model relates to the field of automatic cleaning equipment, and in particular to a filter box for an underwater cleaning robot and an underwater cleaning robot. Background Art

[0002] With the advancement of science and technology, more and more automated equipment has begun to replace manual work, and automatic cleaning devices have gradually entered people's daily lives due to the large demand. Underwater cleaning robots are common automatic cleaning equipment used for underwater cleaning operations. They can move autonomously underwater and brush and absorb leaves, hair and other garbage and debris in the swimming pool. In order to collect the garbage and debris in the swimming pool, underwater cleaning robots mostly collect and filter garbage and debris in the water through filter boxes during the cleaning process. The main body of the existing filter box is composed of a frame and a filter covered on the frame. During cleaning, leaves, hair and other garbage and debris are easily attached to the filter under the action of suction, causing the filter to be blocked, which is not conducive to subsequent garbage cleaning, resulting in poor subsequent self-cleaning ability of the underwater cleaning robot. Utility Model Content

[0003] Based on this, the utility model aims to overcome at least one defect of the prior art and provides a filter box for an underwater cleaning robot and an underwater cleaning robot. The filter box for the underwater cleaning robot has excellent self-cleaning ability and can automatically clean the garbage attached to the main filter without adding a driving mechanism, so that the garbage is cleaned to the bottom of the box body, and the liquid is discharged smoothly on the main filter surface, thereby increasing the cleaning efficiency of the underwater cleaning robot.

[0004] The technical solution is as follows:

[0005] A filter box for an underwater cleaning robot, comprising:

[0006] The box body comprises a frame and a filter screen for filtering, wherein the filter screen comprises a main filter screen;

[0007] A cleaning component is arranged through the main filter and is used for automatically cleaning the main filter of the box body. The cleaning component includes a fan blade and a brush that are coaxially arranged and rotate synchronously. The fan blade is located on the outside of the box body, and the brush is located on the inside of the box body. The coaxial axis of the fan blade and the brush is the rotating shaft of the brush, and the rotating shaft passes through the skeleton.

[0008] The filter box of the underwater cleaning robot is used to collect and filter garbage and debris in the water. During the cleaning process of the underwater cleaning robot, the water pump of the underwater cleaning robot works, and garbage and debris such as leaves and hair enter the filter box from the water inlet together with water. The skeleton of the box body supports the box body, filter screen and cleaning components and can resist the impact of water flow and withstand water pressure. The filter screen of the box body is used to retain debris and discharge water, and the main filter screen retains most of the garbage and discharges a large amount of water. In the process of the box body filtering garbage, most of the garbage is close to the main filter screen of the filter screen, which easily causes garbage such as leaves and hair to stick to the main filter screen under the action of suction, thereby causing the main filter screen to be blocked, which is not conducive to subsequent garbage cleaning. This application sets coaxial and synchronously rotating fan blades and brushes as cleaning components. When the machine is running, the water flow through the main filter will drive the fan blades to rotate, and the brush on the main filter will also rotate continuously, continuously cleaning the residual garbage on the main filter and making it fall to the bottom of the box body to ensure the cleanliness of the main filter and make the liquid discharge smoothly on the main filter surface, thereby ensuring the continuity of the underwater cleaning robot in cleaning garbage. The shaft passing through the skeleton can improve the stability of the shaft when it rotates. This technical solution uses the energy of the water flow inside the underwater cleaning robot to make the fan blades drive the brush to clean the main filter, and realizes automatic cleaning of garbage attached to the main filter without adding a driving mechanism, thereby increasing the cleaning efficiency of the underwater cleaning robot.

[0009] In one embodiment, the brush is arranged close to the main filter.

[0010] In one embodiment, the cleaning assembly further comprises a boss with a through hole at the center, the rotating shaft passes through the through hole and the main filter, and the boss is installed at the skeleton position of the main filter.

[0011] In one embodiment, a limiting groove is provided on the boss, a first screw hole is provided in the limiting groove, a corresponding second screw hole is provided on the frame, and the screw passes through the first screw hole and the second screw hole to fix the boss and the frame.

[0012] In one embodiment, a circular column for supporting the boss is provided on the frame, and the circular column and the boss are at least partially engaged.

[0013] In one embodiment, the fan blade includes a columnar mounting member and a plurality of fan-shaped blades arranged on the columnar mounting member, and the columnar mounting member is connected to the rotating shaft.

[0014] In one embodiment, the brush includes n brush strips spaced apart and arranged in concentric circles, where n≥2.

[0015] In one embodiment, the number of the brush strips is 3, and the three brush strips are evenly spaced and arranged, or the three brush strips are Y-shaped and arranged.

[0016] In one embodiment, the brush bar includes bristles and a bristle protection shell for supporting and mounting the bristles, and a side of the bristles close to the main filter is exposed from the bristle protection shell.

[0017] In one embodiment, the number of the cleaning components is no less than 2.

[0018] The present application also discloses an underwater cleaning robot, comprising the filter box for the underwater cleaning robot as described above, wherein the main filter is close to the water outlet of the underwater cleaning robot.

[0019] The beneficial effect of the present utility model is that the present technical scheme uses coaxially arranged and synchronously rotating fan blades and brushes as cleaning components of the filter screen. When the machine is running, the water pump of the underwater cleaning robot works, and the water flow through the main filter screen will drive the fan blades to rotate, and the brush will also rotate continuously on the main filter screen, continuously cleaning the garbage attached to the main filter screen and making it fall to the bottom of the box body to ensure the cleanliness of the main filter screen and make the liquid discharge smoothly on the surface of the main filter screen, thereby ensuring the continuity of the underwater cleaning robot in cleaning garbage. The present technical scheme utilizes the energy of the internal water flow of the underwater cleaning robot to rotate the fan blades, thereby driving the brush to clean the main filter screen, and realizing the cleaning of garbage attached to the main filter screen without adding a separate driving mechanism, thereby increasing the cleaning efficiency of the underwater cleaning robot.

DETAILED DESCRIPTION

[0027] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0028] Example 1

[0029] like Figures 1 to 4 As shown, this embodiment discloses a filter box for an underwater cleaning robot, comprising:

[0030] The box body 10 includes a frame 11 and a filter screen 12 for filtering (the mesh of the filter screen is very small, and the mesh structure of the filter screen cannot be clearly seen in the figure), and the filter screen 12 includes a main filter screen 121 (the mesh of the main filter screen is also very small, and the mesh structure cannot be clearly seen); the filter screen 12 is arranged on the frame 11 and supported by the frame 11. When the water pump arranged on the underwater cleaning robot is working, garbage and water enter the box body 10, and the water is filtered by the filter screen 12, so that the water is discharged from the filter screen 12 and enters the water outlet of the underwater cleaning robot and is discharged from the water outlet, and garbage such as leaves is intercepted by the filter screen 12 in the box body 10;

[0031] The cleaning component 20 is set to pass through the main filter 121 and is used to automatically clean the main filter 121 of the box body 10. The cleaning component 20 includes a fan blade 21 and a brush 22 that are coaxially arranged and rotate synchronously. The fan blade 21 is located on the outside of the box body 10, and the brush 22 is located on the inside of the box body 10. The coaxial axis of the fan blade 21 and the brush 22 is the rotating shaft 221 of the brush 22, and the rotating shaft 221 passes through the skeleton 11.

[0032] During the cleaning process of the underwater cleaning robot, garbage and debris such as leaves and hair enter the filter box together with water from the water inlet 13. The frame 11 of the box body 10 supports the box body, the filter screen 12 and the cleaning component 20 and can resist the impact of water flow and withstand water pressure. The filter screen 12 of the box body 10 is used to retain debris and discharge water, and the main filter screen 121 thereof serves to retain most of the garbage and discharge a large amount of water. During the process of the box body 10 filtering garbage, most of the garbage is close to the main filter screen 121 of the filter screen 12, which easily causes garbage such as leaves and hair to stick to the main filter screen 121 under the action of suction, causing the main filter screen 121 to be blocked, which is not conducive to subsequent garbage cleaning. The present application sets a coaxial and synchronously rotating fan blade 21 and a brush 22 as a cleaning component 20. When the machine is running, the water flow through the main filter 121 will drive the fan blade 21 to rotate, and the brush 22 will also rotate continuously on the main filter 121, continuously cleaning the residual garbage on the main filter 121 and making it fall into the bottom of the box body 10, so as to ensure the cleanliness of the main filter 121, so that the liquid can be discharged smoothly on the main filter surface, thereby ensuring the continuity of the underwater cleaning robot cleaning garbage. The rotating shaft 221 passes through the skeleton 11 to improve the stability of the rotating shaft 221 when it rotates. The technical solution is to use the energy of the water flow inside the underwater cleaning robot to make the fan blade 22 drive the brush 21 to clean the main filter 121, and realize the automatic cleaning of the garbage attached to the main filter 121 without adding a driving mechanism, thereby increasing the cleaning efficiency of the underwater cleaning robot.

[0033] Furthermore, the brush 22 in this embodiment is arranged close to the main filter 121. The brush 22 is arranged close to the main filter 121, so that the force between the brush 22 and the main filter 121 can be increased, thereby improving the cleaning ability of the brush 22.

[0034] Furthermore, if Figure 2 , Figure 6 As shown, the cleaning assembly 20 in this embodiment also includes a boss 23 with a through hole 231 in the center, and the rotating shaft 221 passes through the through hole 231 and the main filter 121; the boss 23 is installed at the position of the skeleton 11 of the main filter 121 to improve the stability of the boss 23. The design of the boss 23 is convenient for installing the fan 21 and the brush 22 on the main filter 121 on the one hand, and can separate the fan 21 and the main filter 121 on the other hand, so as to ensure the driving force for the fan 21 to rotate when the water flows through the main filter 121, and can also provide a tightening force to the brush 22 in the direction of the rotation of the brush 22; the brush 22 is close to the main filter 121 to ensure the cleanliness of the main filter 121, and the design of the boss 23 can reserve some space so that the bristles 2221 of the brush 22 have enough rotation space.

[0035] Furthermore, a limiting groove 232 is provided on the boss 23, a first screw hole is provided in the limiting groove 232, and a corresponding second screw hole is provided on the frame 11, and the screw passes through the first screw hole and the second screw hole to fix the boss 23 and the frame 11. The setting of the limiting groove 232 reserves the position of the first screw hole, so that the boss 23 will not protrude after the screw is fixed, and thus will not affect the rotation of the cleaning component 20. During the rotation of the cleaning component 20, the surface of the brush 22 in contact with the boss 23 will rub against the boss 23, and long-term friction may cause damage to the boss 23. The detachable fixing method of the boss 23 and the frame 11 facilitates the replacement of the damaged boss 23. In other embodiments, other fastening and installation methods may also be adopted, or the frame 11 and the boss 23 may also be integrally formed.

[0036] Furthermore, the frame 11 is provided with a circular column 111 for supporting the boss 23, and the circular column 111 and the boss 23 are at least partially engaged. Furthermore, the circular column 111 is provided with an arc groove, and the protrusion 23 is partially engaged in the arc groove. Such a design can facilitate the rough positioning or quick positioning of the boss 23 during installation. In other embodiments, the boss 23 may also be provided with an arc groove, and the circular column 111 may be partially engaged in the arc groove.

[0037] Furthermore, the fan blade 21 in this embodiment includes a columnar mounting member 211 and a plurality of fan-shaped blades 212 arranged on the columnar mounting member 211, and the columnar mounting member 211 is connected to the rotating shaft 221. When installing the fan blade 21, firstly, the rotating shaft 221 of the brush 22 is passed through the through hole 231 at the center of the boss 23, and then the columnar mounting member 211 is screwed onto the rotating shaft 221 of the brush 22 from the other side. Since the fan-shaped blade 212 and the columnar mounting member 211 are connected together, and the columnar mounting member 211 is connected to the rotating shaft 221 of the brush 22, when the fan-shaped blade 212 rotates under the action of the water flow, the columnar mounting member 211 rotates, driving the rotating shaft 221 to rotate, thereby realizing the rotation of the brush 22 and achieving the purpose of cleaning the garbage on the main filter 121. Furthermore, a hole matching the rotating shaft 221 is provided at the center of the columnar mounting member 211 , so as to realize coaxial assembly of the columnar mounting member 211 and the rotating shaft 221 .

[0038] Furthermore, the brush 22 in this embodiment includes n brush strips 222 arranged at intervals in concentric circles, where n≥2. The concentric circle distribution arrangement can make the cleaning trajectory of the brush strip 22 consistent with the rotation trajectory of the fan blade 21. The center of the concentric circle is the position of the rotating shaft 221. Furthermore, the number of the brush strips 222 is 3, and the 3 brush strips 222 are arranged at equal intervals, or the 3 brush strips 222 are arranged in a Y-shaped distribution. Generally speaking, the more brush strips 222 there are, the better the cleaning effect on the main filter 121, but when the number is too large, the cost will increase, and it will also affect the drainage effect. Taking all factors into consideration, the best effect is achieved when the number is 3.

[0039] Furthermore, the brush strip 222 includes bristles 2221 and a bristle protection shell 2222 for supporting and installing the bristles 2221. The side of the bristles 2221 close to the main filter 121 is exposed from the bristle protection shell 2222. The bristle protection shell 2222 is used to install the bristles 2221 on the one hand, and to provide sufficient support for the cleaning work of the bristles on the other hand. The reason is that the bristles 2221 are subjected to relatively large resistance and water pressure when cleaning the main filter 121, and the bristles 2221 are flexible structures and are easily deformed by force, which affects the cleaning effect. The rigid bristle protection shell 2222 can prevent the bristles 2221 from deforming and ensure the cleaning efficiency.

[0040] Furthermore, the number of the cleaning components 20 is not less than 2. When there is only one cleaning component 20, the cleaning area of ​​the main filter surface 121 is limited. If there are too many cleaning components 20, drainage will be affected and the cost will be increased. Considering various factors, the best effect is achieved when there are two cleaning components 20 in this embodiment.

[0041] Furthermore, the main filter screen 121 is inclined to the plane where the water inlet 13 of the box body 10 is located. Furthermore, in the present embodiment, the water inlet 13 of the box body 10 is located at the bottom of the box body 10, the main filter screen 121 is inclined to the plane where the water inlet 13 of the box body 10 is located, and the top space of the box body 10 is larger than the bottom space, that is, the box body 10 is designed to be wide at the top and narrow at the bottom. Designing the box body 10 to be wide at the top and narrow at the bottom facilitates the installation and disassembly of the filter box in the underwater cleaning robot, and can also expand the volume of the box body 10 to accommodate more garbage. Furthermore, a handle is also provided above the top of the box body 10 (not shown in the figure due to viewing angle issues) to facilitate the lifting of the filter box.

[0042] An underwater cleaning robot includes the filter box for the underwater cleaning robot as described above, wherein the main filter 121 is close to the water outlet of the underwater cleaning robot. The main filter 121 has a large filtering area and is arranged close to the water outlet of the underwater cleaning robot. When the water pump of the robot is working, it can effectively drain water and store garbage in the box body 10. Since the main filter 121 is arranged close to the water outlet of the underwater cleaning robot, it is more likely that garbage will be attached to the main filter 121. At this time, the cleaning component 20 can better play a cleaning effect, avoid clogging of the main filter 121, and ensure the effective work of the underwater cleaner.

[0043] Obviously, the above embodiments of the utility model are only examples for clearly explaining the technical solution of the utility model, and are not intended to limit the specific implementation methods of the utility model.
