DETAILED DESCRIPTION

[0025] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of this specification. For ordinary technicians in this field, this specification can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0026] It should be understood that, for the convenience of describing this specification, the positional relationships indicated by the terms "center", "upper surface", "lower surface", "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "periphery", "outer", etc. are based on the positional relationships shown in the drawings, rather than indicating that the devices, components or units referred to must have a specific positional relationship, and should not be understood as limiting this specification. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

[0027] The embodiments of this specification provide a cleaning brush. After the crystal growth is completed, there will be solid particles in the furnace of the crystal growth furnace, and a vacuum cleaner is needed to clean the furnace. Since there are areas such as curvatures and right-angled edges inside the furnace body that are difficult to clean, it is difficult for a general cleaning brush to completely remove them. In order to completely clean the inside of the crystal growth furnace and avoid the retention of solid particles in areas that are difficult to clean, a cleaning brush provided with an angle adjustment mechanism, a first brush head and a second brush head can be used for cleaning. The angle adjustment mechanism can adjust the angle between the first brush head and the second brush head to adapt to the complex situations such as curvatures and right-angled edges inside the furnace body, thereby achieving the purpose of completely cleaning the crystal growth furnace. It can be understood that in addition to cleaning the furnace of the crystal growth furnace, the cleaning brush can also clean other equipment, which is not limited here.

[0028] Figure 1 It is a schematic diagram of the structure of a cleaning brush according to some embodiments of the present specification.

[0029] In some embodiments, the cleaning brush 10 may include a handle 100 , a brush head 200 , and an angle adjustment mechanism 300 .

[0030] The handle 100 is a device that can support the brush head 200. In some embodiments, Figure 1 As shown, the brush head 200 can be arranged at one end of the handle 100. The operator can hold the handle 100, or can control the robot arm to carry the handle 100 for cleaning, so as to drive the brush head 200 to perform cleaning operations on equipment such as the furnace.

[0031] The brush head 200 refers to a device that can directly clean the cleaning surface. The cleaning surface refers to the surface that needs to be cleaned. In some embodiments, the brush head 200 may include bristles, which can remove the attached objects on the cleaning surface through their own friction and force conduction. For more information about bristles, please refer to Figure 3 and its related description.

[0032] In some embodiments, the brush head 200 may include a first brush head 210 and a second brush head 220, and the bristles may be disposed on the first brush head 210 and the second brush head 220. The first brush head 210 and the second brush head 220 may be connected via a connecting shaft 230, and the first brush head 210 and the second brush head 220 may rotate independently around the connecting shaft 230.

[0033] The first brush head 210 and the second brush head 220 refer to components that can constitute the brush head 200. The connecting shaft 230 refers to a component that can be used to connect the first brush head 210 and the second brush head 220. In some embodiments, the connecting shaft 230 may include a pin, a first hole is provided on the side of the first brush head 210 close to the second brush head 220, and a second hole is provided on the side of the second brush head 220 close to the first brush head 210. The pin on the connecting shaft 230 passes through the first hole and the second hole to connect the first brush head 210 and the second brush head 220. In some embodiments, the brush head may have a variety of shapes. For example, an irregular sheet structure with a serrated structure on the edge, etc.

[0034] It is understandable that the brush head 200 may also include more than two brush heads, for example, three brush heads, four brush heads, etc. The two or more brush heads are connected end to end in a row, and the adjacent brush heads may be connected via a connecting shaft 230. The brush head 200 includes more than two brush heads, which can adapt to a cleaning surface with a more complex shape to achieve the purpose of comprehensive cleaning.

[0035] The first brush head 210 and the second brush head 220 can both rotate independently around the connection axis 230, which means that the first brush head 210 and the second brush head 220 can rotate around the connection axis 230 at different angles and / or directions.

[0036] In some embodiments, when the brush head 200 includes more than two brush heads, one or more of the brush heads may be fixed relative to other components (e.g., the connecting portion 240 below), while other brush heads may be rotatable, thereby avoiding interference in relative rotation between the multiple brush heads.

[0037] The angle adjustment mechanism 300 is a device for adjusting the angle between the first brush head 210 and the second brush head 220. In some embodiments, the angle adjustment mechanism 300 may include a control unit 310 and a connecting assembly 320. For more information about the angle adjustment mechanism 300, see Figure 5 and its related description.

[0038] The angle between the first brush head 210 and the second brush head 220 refers to the angle of rotation when the side of the first base 211 without bristles rotates toward the side of the second base 221 without bristles. When the side of the first base 211 without bristles overlaps with the side of the second base 221 without bristles, that is, the angle between the back end surfaces of the first base 211 and the second base 221. For example, Figure 4A As shown, the angle α between the first brush head 210 and the second brush head 220 is 180°. Figure 4B As shown, the angle α between the first brush head 210 and the second brush head 220 is greater than 90° and less than 180°. Figure 4C As shown, the angle α between the first brush head 210 and the second brush head 220 is less than 90°. It can be understood that the angle between the first brush head 210 and the second brush head 220 can be referred to as the angle between the first base 211 and the second base 221. When the first base 211 and the second base 221 are chamfered, the angle between the first base 211 and the second base 221 can be greater than 180°.

[0039] In some embodiments of the present specification, the angle between the first brush head 210 and the second brush head 220 that can rotate independently around the connecting shaft 230 is adjusted by the angle adjustment mechanism 300, so that the shape of the brush head 200 can be adjusted to adapt to a cleaning surface with a more complex shape to achieve the purpose of comprehensive cleaning.

[0040] Figure 2 It is a schematic diagram of the structure of a cleaning brush according to some other embodiments of the present specification.

[0041] In some embodiments, the brush head 200 may further include a connecting portion 240 , and the connecting shaft 230 may be disposed on the connecting portion 240 .

[0042] The connecting portion 240 refers to a component that can be used to connect the handle 100 and the connecting shaft 230. Since the brush head 200 is connected via the connecting shaft 230, and the connecting shaft 230 is disposed on the connecting portion 240, when the connecting portion 240 deflects and / or rotates relative to the handle 100, the brush head 200 can be driven to deflect and / or rotate as a whole, so that the cleaning point is directly opposite to the brush head 200, and / or the opening and closing directions of the first brush head 210 and the second brush head 220 are matched with the directions of the protrusions, depressions, etc. of the cleaning surface.

[0043] In some embodiments, the connecting portion 240 is rotatably connected to the handle 100. The connecting portion 240 is rotatably connected to the handle 100, which means that the connecting portion 240 can be deflected relative to the handle 100. In some embodiments, the brush head 200 can be constructed to be able to deflect relative to the axis of the distal end of the handle 100. That is, the connecting portion 240 and the handle 100 deflect, which can drive the brush head 200 as a whole to deflect relative to the axis P of the distal end of the handle 100. The connecting portion 240 can deflect relative to the handle 100, which can mean that the relative angle between the axis M of the connecting portion 240 and the axis P of the distal end of the handle 100 can change. The position of the axis M of the connecting portion 240 on the connecting portion 240 can be related to the shape of the connecting portion 240. For example, when the connecting portion 240 is cylindrical or annular, the axis M of the connecting portion 240 is the axis of the cylindrical or annular shape.

[0044] In some embodiments, the connection portion 240 may include a component that can achieve deflection. For example, the connection portion 240 may include a ball head, and the handle 100 may include a ball sleeve. The ball head and the ball sleeve may cooperate with each other so that the connection portion 240 and the handle 100 can be deflected. For another example, the connection portion 240 may include a first side ear, and the handle 100 may include a second side ear. The first side ear includes a first pin hole, and the second side ear includes a second pin hole. The first pin hole and the second pin hole are connected by a pin, so that the connection portion 240 and the handle 100 can be deflected. For another example, Figure 2 As shown, the handle 100 and the connecting portion 240 can be connected by a bellows, so that the connecting portion 240 and the handle 100 can be deflected. The bellows connection can make the connection stable and can withstand a certain degree of torsional deformation.

[0045] In some embodiments, the connection portion 240 may include a deflection drive mechanism, which may drive the connection portion 240 to deflect relative to the handle 100, thereby driving the brush head 200 to deflect relative to the axis P at the distal end of the handle 100. The deflection drive mechanism may include a linear motor, a rotary motor, etc. In some embodiments, the brush head 200 after the overall deflection can more conveniently clean the cleaning point.

[0046] The "proximal end" and "distal end" involved in some embodiments of this specification may indicate a direction, which means that along the axial direction of the cleaning brush 10 (for example, the extension direction of the handle 100), the direction of the side close to the operator and away from the brush head 200 is the "proximal end", and the direction of the side close to the brush head 200 and away from the operator is the "distal end". "Proximal end" and "distal end" should not be understood as indicating only ends. "Proximal end" and "distal end" may refer to the endpoint, end face, end, part close to the end and having a certain length, etc. of the cleaning brush 10 or its components. Figure 2 As shown, the axis P of the distal end of the handle 100 refers to the central axis in the extending direction of the distal end of the handle 100 .

[0047] In some embodiments, the connection portion 240 is rotatably connected to the handle 100. The connection portion 240 is rotatably connected to the handle 100, which means that the connection portion 240 can rotate relative to the handle 100. In some embodiments, the brush head 200 can be configured to rotate around the axis M of the connection portion 240. That is, the rotation of the connection portion 240 and the handle 100 can drive the brush head 200 as a whole to rotate around the axis M of the connection portion 240.

[0048] In some embodiments, the connection portion 240 may include a component that can achieve rotation. For example, the connection portion 240 may include a ball head, the handle 100 may include a ball sleeve, the ball head and the ball sleeve may cooperate with each other, so that the connection portion 240 and the handle 100 can rotate. For another example, the connection portion 240 may include an annular groove, the handle 100 may include an annular protrusion, the annular groove and the annular protrusion can rotatably cooperate, so that the connection portion 240 and the handle 100 can rotate.

[0049] In some embodiments, the connection portion 240 may include a rotation drive mechanism, which may drive the connection portion 240 to rotate relative to the handle 100, thereby driving the brush head 200 to rotate around the axis M of the connection portion 240. The rotation drive mechanism may include a linear motor, a rotation motor, etc. The overall rotation of the brush head 200 can make the opening and closing directions of the first brush head 210 and the second brush head 220 match the directions of the protrusions, depressions, etc. of the cleaning surface, thereby achieving effective cleaning. The opening and closing directions of the first brush head 210 and the second brush head 220 match the directions of the protrusions, depressions, etc. of the cleaning surface, which means that after the first brush head 210 and / or the second brush head 220 rotates a certain angle around the connection shaft 230, the brush head 200 can just extend into a certain depression, or when it fits a certain protrusion, the corresponding opening and closing directions of the first brush head 210 and the second brush head 220.

[0050] In some embodiments of the present specification, by constructing the brush head 200 to be able to deflect relative to the axis of the distal end of the handle 100, the position of the brush head 200 can be adjusted accurately and efficiently when the cleaning point is not directly opposite the brush head 200, thereby reducing the difficulty of operation; and / or by constructing the brush head 200 to be able to rotate around the axis M of the connecting portion 240, the opening and closing directions of the first brush head 210 and the second brush head 220 can be adjusted accurately and efficiently when the opening and closing directions of the first brush head 210 and the second brush head 220 do not match the directions of the protrusions, depressions, etc. of the cleaning surface, so as to better clean the protrusions, depressions, and other difficult-to-clean areas of the cleaning surface. When the position of the brush head 200 and / or the opening and closing directions of the first brush head 210 and the second brush head 220 are adjusted, the cleaning can be completed efficiently and more thoroughly by adjusting the angle between the first brush head 210 and the second brush head 220.

[0051] Figure 3 It is a schematic diagram of the structure of a brush head according to some embodiments of this specification.

[0052] In some embodiments, the first brush head 210 may include a first base 211 and first bottom bristles 212 and side bristles 213 disposed on the first base 211 ; the second brush head 220 may include a second base 221 and second bottom bristles 222 and side holes 223 disposed on the second base 221 .

[0053] The first base 211 refers to a component that can support the bristles on the first brush head 210. The bristles may include first bottom bristles 212 and side bristles 213. In some embodiments, the shape of the first base 211 may be a column, such as a cylinder, a cone, a cube, a cuboid, etc. In some embodiments, the first base 211 may include two end surfaces disposed opposite to each other, namely, a first back end surface facing the handle 100, and a first bottom end surface away from the handle 100.

[0054] The first bottom bristles 212 refer to the bristles on the first bottom end surface, that is, the bristles arranged away from the handle 100. In some embodiments, the length and material of the first bottom bristles 212 can be set according to actual usage. In some embodiments, the first bottom bristles 212 can be distributed on the entire surface of the first base 211 away from the handle 100, and can be evenly distributed or unevenly distributed. In some embodiments, as Figure 1 As shown, the first bottom bristles 212 may be distributed in a ring shape on the surface of the first base portion 211 on the side away from the handle 100 , with no bristles arranged in the middle.

[0055] The side bristles 213 are bristles located between the handle 100 and the first bottom bristles 212 and extending in a different direction from the first bottom bristles 212. For example, the bristles are located on the side wall between the first back end face and the first bottom end face. The material and distribution of the side bristles 213 are similar to those of the first bottom bristles 212 and are not described in detail here. In some embodiments, at least part of the side bristles 213 is located on a side close to the second brush head 220. For example, Figure 3 As shown, the side bristles 213 are located on a side close to the second brush head 220. The length of the side bristles 213 on the side not close to the second brush head 220 can be set according to actual usage; the length of the side bristles 213 on the side close to the second brush head 220 is related to the side hole 223 on the second brush head 220, that is, the length of the side bristles 213 on the side close to the second brush head 220 needs to be less than the depth of the side hole 223, so that when the first brush head 210 and the second brush head 220 are arranged horizontally, the side bristles 213 on the side close to the second brush head 220 can completely enter the side hole 223, avoiding the generation of a force to open the first brush head 210 and the second brush head 220.

[0056] The side close to the second brush head 220 refers to the side of the side wall between the first back end surface and the first bottom end surface, which is closest to the second brush head 220 .

[0057] The second base 221 refers to a component that can support the bristles on the second brush head 220. The bristles may include second bottom bristles 222. In some embodiments, the shape of the second base 221 may be a column, such as a cylinder, a cone, a cube, a cuboid, etc. In some embodiments, the second base 221 may include two end surfaces disposed opposite to each other, namely, a second back end surface facing the handle 100, and a second bottom end surface away from the handle 100.

[0058] The second bottom bristles 222 refer to the bristles on the second bottom end surface. The length, material, and distribution of the second bottom bristles 222 are similar to those of the first bottom bristles 212, and will not be described in detail.

[0059] The side hole 223 refers to a groove opened on the side wall between the second back end face and the second bottom end face and close to the first brush head 210. The side close to the first brush head 210 refers to the side of the side wall between the second back end face and the second bottom end face that is closest to the first brush head 210. The size and shape of the side hole 223 need to match the size of the side bristles 213 on the side of the first brush head 210 close to the second brush head 220, that is, the length, width, and depth of the side hole 223 need to be able to accommodate the side bristles 213 on the side of the first brush head 210 close to the second brush head 220.

[0060] In some embodiments, the first base portion 211 and the second base portion 221 may be connected via a connecting shaft 230 , so that the first brush head portion 210 and the second brush head portion 220 are connected.

[0061] In some embodiments, at least part of the side bristles 213 enter or emerge from the side hole 223 as the angle between the first base 211 and the second base 221 changes. For more information about the angle between the first base 211 and the second base 221, see Figure 1 and its related description.

[0062] Figure 4A is a schematic diagram of an angle between a first base and a second base according to some embodiments of the present specification; Figure 4B is a schematic diagram of the angle between the first base and the second base according to some other embodiments of the present specification; Figure 4C Schematic diagram of the angle between the first base and the second base according to some other embodiments of this specification. Figure 4A As shown, when the angle α between the first base 211 and the second base 221 is equal to 180°, at least part of the side bristles 213 enter the side holes 223; Figure 4BAs shown, when the angle α between the first base 211 and the second base 221 is greater than 90° and less than 180°, at least part of the side bristles 213 partially enter the side holes 223 and partially emerge from the side holes 223; Figure 4C As shown, when the angle α between the first base portion 211 and the second base portion 221 is less than 90°, at least part of the side bristles 213 are exposed from the side holes 223 .

[0063] In some embodiments of the present specification, by cooperating at least part of the side bristles 213 on one side close to the second brush head 220 with the side hole 223, it can be achieved that when the angle between the first base 211 and the second base 221 is equal to 180° (i.e., horizontal setting), at least part of the side bristles 213 enter the side hole 223 to avoid generating a force to open the first brush head 210 and the second brush head 220; when the angle between the first base 211 and the second base 221 is not equal to 180° (i.e., non-horizontal setting), at least part of the side bristles 213 are partially exposed or expose the side hole 223 to increase the coverage area of ​​the bristles and improve the cleaning effect.

[0064] Figure 5 It is a schematic diagram of the structure of a cleaning brush according to some other embodiments of the present specification.

[0065] In some embodiments, the angle adjustment mechanism 300 may include a control portion 310 and a connection assembly 320 .

[0067] In some embodiments, the first connection line 321 and the second connection line 322 may be disposed in the channel 110 of the handle 100, and the first connection line 321 and the second connection line 322 may be long axis-shaped structures for driving the first brush head 210 and the second brush head 220 to rotate around the connection axis 230. In some embodiments, the first connection line 321 and the second connection line 322 may be made of flexible materials, that is, the first connection line 321 and the second connection line 322 may have deformation capability.

[0068] In some embodiments, the first brush head 210 can rotate around the connecting shaft 230 under the action of the first connecting line 321, and / or the second brush head 220 can rotate around the connecting shaft 230 under the action of the second connecting line 322, so as to adjust the angle between the first brush head 210 and the second brush head 220. In some embodiments, a torsion spring is provided at the connecting shaft 230, so that when the first connecting line 321 and / or the second connecting line 322 are relaxed, the first brush head 210 and / or the second brush head 220 can be automatically reset.

[0069] In some embodiments, the control unit 310 may include a first control mechanism 311 and a second control mechanism 312 , wherein the first control mechanism 311 is connected to a first connection line 321 , and the second control mechanism 312 is connected to a second connection line 322 .

In some embodiments, one end of the channel 110 is located at the brush head 200, and at least part of the angle adjustment mechanism 300 (e.g., the first connecting line 321 and the second connecting line 322) is disposed in the channel 110. The channel 110 can protect and accommodate other components (e.g., the first connecting line 321, the second connecting line 322, the first pipe 400 below, the second pipe 700 below, etc.), and can play a role in converging the above-mentioned other components.

[0075] Figure 6 It is a schematic diagram of the air suction state of the cleaning brush shown in some embodiments of the present specification.

[0076] In some embodiments, the cleaning brush 10 may further include a first pipe 400, a suction pump 500, and a dust collecting device 600. Figure 6 As shown, one end of the first pipe 400 is connected to the dust collecting device 600, the other end of the first pipe 400 is located at the brush head 200, and the suction pump 500 is located on the first pipe 400. The brush head 200 refers to an area within a preset distance range from the center (e.g., geometric center, centroid, etc.) of the brush head 200. The preset distance range can be manually set.

[0077] The first pipe 400 is a pipe for conveying solid particles sucked by the brush head 200 to the dust collecting device 600. The diameter and length of the first pipe 400 can be designed according to actual conditions. In some embodiments, the material of the first pipe 400 can include metal, plastic, rubber, composite materials, etc. In some embodiments, at least part of the first pipe 400 is located in the channel 110, and the channel 110 can protect and accommodate the first pipe 400.

[0078] The suction pump 500 refers to a pump for conveying exhaust gas.

[0079] The dust collecting device 600 refers to a component that can collect solid particles. For example, the dust collecting device 600 may include an isolation net, a dust removal bag, etc. By setting the dust collecting device 600, the sucked solid particles can be collected.

[0080] In some embodiments, under the action of the suction pump 500, solid particles can enter the dust collecting device 600 through the brush head 200 and the first pipe 400 to achieve more comprehensive cleaning.

[0081] In some embodiments of the present specification, the bristles of the brush head 200 are used to clean while the solid particles are sucked out by the suction pump 500, so that the cleaning can be more thorough and more efficient.

[0082] Figure 7It is a schematic diagram of the blowing state of the cleaning brush shown in some embodiments of the present specification.

[0083] In some embodiments, the cleaning brush 10 may further include a second pipe 700 and an air source 800. Figure 7 As shown, one end of the second pipeline 700 is connected to the air source 800 , and the other end of the second pipeline 700 is located at the brush head 200 .

[0084] The second pipe 700 is a pipe for delivering gas to the brush head 200. The diameter, length, and material of the second pipe 700 are similar to those of the first pipe 400, and are not described in detail. In some embodiments, at least a portion of the second pipe 700 is located in the channel 110.

[0085] The gas source 800 refers to a device for providing gas. In some embodiments, the gas source 800 may include a compressor. In some embodiments, the gas compressed by the compressor may include air, nitrogen, helium, etc.

[0086] In some embodiments, under the action of the gas source 800, the compressed gas can be sprayed toward the cleaning surface through the second pipe 700 and the brush head 200 to blow off the solid particles on the cleaning surface, thereby achieving the purpose of cleaning.

[0087] In some embodiments of the present specification, the cleaning is more thorough and more efficient by spraying gas through the gas source 800 while cleaning with the bristles of the brush head 200. When the first pipeline 400, the suction pump 500, the dust collecting device 600, the second pipeline 700 and the gas source 800 are included at the same time, the suction of solid particles and the spraying of gas can cooperate with each other to better complete the cleaning.

[0088] In some embodiments, Figure 1 As shown, the first base 211 and the second base 221 may both include a bottom wall connected to the handle 100 and a side wall arranged around the bottom wall, the bottom bristles (i.e., the first bottom bristles 212 and the second bottom bristles 222) may be arranged on the end of the side wall away from the bottom wall, and the side bristles 213 may be arranged on the side wall. The space enclosed by the side wall and the bottom wall is connected to the channel 110. The ports of the first pipe 400 and / or the second pipe 700 are both arranged in the space enclosed by the above-mentioned side wall and the bottom wall.

[0089] In some embodiments, a camera may be provided at one end of the handle 100. The end of the handle 100 refers to the end of the handle close to the brush head 200.

[0090] In some embodiments, the operator can hold the handle 100 for cleaning. By holding the handle 100 for cleaning, flexibility is high and the equipment is simple. In some embodiments, the operator can control the mechanical arm to carry the handle 100 for cleaning. By controlling the mechanical arm to carry the handle 100 for cleaning, work safety is improved, and automation and intelligence can be achieved.

[0091] In some embodiments, when the cleaning position of the cleaning brush 10 is not easy to observe, a camera can be provided at one end of the handle 100 to achieve better operation. For example, when the cleaning brush 10 is used to clean the furnace, the camera can capture the image of the furnace, and then transmit the image of the furnace to an external display device, and then the operator can move the position of the handle 100 based on the image in the display device. When the mechanical arm drives the handle 100 to move, the operator can move the handle 100 through the control device of the mechanical arm.

[0092] In some embodiments of the present specification, by providing a camera at one end of the handle 100, it is possible to avoid incomplete cleaning caused by the cleaning brush 10 not being able to clearly see the cleaning surface when cleaning a location that is difficult to observe.

[0093] The beneficial effects that may be brought about by the embodiments of this specification include but are not limited to: (1) By adjusting the angle between the first brush head 210 and the second brush head 220 that can rotate independently around the connecting shaft 230 through the angle adjustment mechanism 300, the shape of the brush head 200 can be adjusted to adapt to the cleaning surface with more complex shapes and achieve the purpose of comprehensive cleaning. (2) By constructing the brush head 200 to be able to deflect relative to the axis of the distal end of the handle 100, the position of the brush head 200 can be adjusted accurately and efficiently when the cleaning point is not directly facing the brush head 200, thereby reducing the difficulty of operation; and / or by constructing the brush head 200 to be able to rotate around the axis M of the connecting part 240, the opening and closing directions of the first brush head 210 and the second brush head 220 are not matched with the direction of the protrusions, depressions, etc. of the cleaning surface, and the first brush head 210 and the second brush head 220 can be adjusted accurately and efficiently, thereby better cleaning the protrusions, depressions, and other difficult-to-clean areas on the cleaning surface. After the position of the brush head 200 and / or the opening and closing direction of the first brush head 210 and the second brush head 220 are adjusted, the cleaning can be completed efficiently and more thoroughly by adjusting the angle between the first brush head 210 and the second brush head 220. (3) By cooperating at least part of the side bristles 213 on one side close to the second brush head 220 with the side hole 223, when the angle between the first base 211 and the second base 221 is equal to 180° (i.e., horizontal setting), at least part of the side bristles 213 enter the side hole 223 to avoid generating a force to open the first brush head 210 and the second brush head 220; when the angle between the first base 211 and the second base 221 is not equal to 180° (i.e., non-horizontally setting), at least part of the side bristles 213 are partially exposed or exposed from the side hole 223 to increase the coverage area of ​​the bristles and improve the cleaning effect. (4) By controlling the first connecting line 321 through the first control mechanism 311, and / or the second connecting line 322 through the second control mechanism 312, the first brush head 210 and / or the second brush head 220 can be driven to rotate around the connecting shaft 230, so as to adjust the angle between the first brush head 210 and the second brush head 220 to adapt to different cleaning surfaces. (5) While cleaning with the bristles of the brush head 200, the suction pump 500 sucks solid particles and / or the gas source 800 sprays gas, which can make the cleaning more thorough and more efficient. (6) By providing a camera at one end of the handle 100, it can be avoided that the cleaning brush 10 is not able to clearly see the cleaning surface when cleaning a position that is difficult to observe, resulting in incomplete cleaning.
