[0002] A sweeping robot, also known as an automatic cleaning machine, smart vacuum cleaner, robot vacuum cleaner, etc., is a type of smart home appliance that can automatically complete floor cleaning in the room with a certain degree of artificial intelligence. It generally uses brushing and vacuuming to absorb debris on the ground into its own garbage storage box, thereby completing the function of floor cleaning.

[0003] The Chinese patent application with publication number CN108577685A discloses a dust cleaning device for a sweeping robot. The patent application solves the problem that conventional sweeping robots are controlled by sensors to avoid hitting walls or table corners, which increases costs and puts pressure on consumers; and the dust cannot be automatically cleaned after cleaning, and the dust needs to be cleaned out from the inside manually. However, the above-mentioned sweeping robots still have the following shortcomings:

[0004] (1) The cleaning brush at the bottom of the sweeping robot has a limited cleaning range of the ground, and the cleaning range of the brush cannot be freely adjusted. In the existing sweeping robots with adjustable cleaning range, the brush easily drives dust to move back and forth during the back and forth movement, resulting in low cleaning efficiency. In addition, the components for adjusting the cleaning range of the existing sweeping robots with adjustable cleaning range cannot be disassembled;

[0005] (2) After the cleaning brush cleans the dust, dust and hair are stuck to the brush, making it inconvenient to automatically clean the brush;

[0019] Beneficial Effects

[0020] The present invention provides a sweeping robot that is easy to clean. Compared with the prior art, it has the following beneficial effects:

[0021] (1) Through the setting of the telescopic adjustment mechanism, the cleaning radius of the bristles can be adjusted, the cleaning range of the bristles on the ground is expanded, and the dust and impurities around the robot body can be efficiently gathered and gathered at the bottom of the robot body for absorption, which greatly improves the cleaning efficiency of the ground.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention provides three technical solutions, including the following embodiments:

[0035] Example 1

[0036] See also Figure 1-Figure 5 A sweeping robot that is easy to clean includes a robot body 1. The robot body 1 is a sweeping robot. The sweeping robot forms vacuum suction through an electric motor and combines a sensor and a navigation system to achieve autonomous cleaning and obstacle avoidance. The robot body 1 is provided with a detachable telescopic adjustment mechanism 2;

[0037] The telescopic adjustment mechanism 2 includes a pentagonal plate 21 arranged above the robot body 1, a round box with an open top is arranged in the center of the pentagonal plate 21, five pipe sleeves are installed around the round box, and the five pipe sleeves are connected to the round box. The design of the pentagonal plate 21 provides a stable support for the subsequent structure, and the top of the pentagonal plate 21 is rotatably connected to a large gear 22, specifically, the large gear 22 is rotatably connected to the bottom wall of the round box through a rotating shaft, a triangular seat 23 is fixed on the pentagonal plate 21, a small gear 24 is fixed on the top of the triangular seat 23, the large gear 22 is meshed with the small gear 24, and a motor 25 is fixed at the bottom of the triangular seat 23, and the motor 25 is a three-phase asynchronous motor The machine can rotate forward and reverse, is controlled by an external switch, and is electrically connected to the built-in power supply of the robot body 1. The motor 25 drives the small gear 24 to rotate. Five arc grooves 26 are penetrated on the large gear 22. Five moving rods 27 are slidably connected to the inner surface of the pentagonal plate 21. The tops of the five moving rods 27 are fixed with limiting columns 28. The tops of the five limiting columns 28 penetrate the arc groove 26 and extend to the outside of the arc groove 26. The outer surfaces of the five limiting columns 28 are slidably connected to the inner surface of the arc groove 26. The design of the arc groove 26 is that when the large gear 22 rotates, the arc groove 26 can drive the limiting columns 28 to move radially outward.

[0038] By setting the telescopic adjustment mechanism 2, the cleaning radius of the bristles 35 can be adjusted, the cleaning range of the bristles 35 on the ground is expanded, and the dust and impurities around the robot body 1 can be efficiently gathered and gathered at the bottom of the robot body 1 for absorption, thereby greatly improving the cleaning efficiency of the ground.

[0039] Five insertion rods 4 are fixed to the bottom of the pentagonal plate 21 , and five sockets 5 are fixed to the top of the robot body 1 . The bottom ends of the five insertion rods 4 extend into the inside of the sockets 5 .

[0040] The five insertion rods 4 are all matched with the size of the socket 5, and the five limiting columns 28 are all matched with the size of the arc groove 26. The design of the insertion rods 4 and the socket 5 enables the telescopic adjustment mechanism 2 to be quickly assembled on the robot body 1.

[0041] The telescopic adjustment mechanism 2 can be quickly assembled to the robot body 1 through the cooperation of the plug rod 4 and the socket 5, and can be quickly installed on a sweeping robot that does not have an adjustable cleaning range. When cleaning in a narrow space, the telescopic adjustment mechanism 2 and the mobile cleaning component 3 can be removed in time to facilitate the passage of the sweeping robot. When it is necessary to increase the cleaning range, the telescopic adjustment mechanism 2 and the mobile cleaning component 3 can be installed in time to improve the cleaning efficiency. The assembled design is very flexible.

[0042] Example 2

[0043] Based on Example 1, see Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, a mobile cleaning assembly 3 is provided at one end of the five moving rods 27 that are away from each other. The mobile cleaning assembly 3 includes a fixed seat 31 fixed at one end of the five moving rods 27. A square tube 32 is fixed to the top of the fixed seat 31. A square rod 33 is slidably connected to the inner surface of the square tube 32. The bottom end of the square rod 33 passes through the fixed seat 31 and extends to the bottom of the fixed seat 31.

[0044] A cleaning plate 34 is fixed to the bottom end of the square rod 33, and bristles 35 are fixed to the bottom of the cleaning plate 34. The top ends of the five square tubes 32 are rotatably connected to screw rods 36, and a limiting plate 37 is fixed to the outer surface of the screw rods 36. The setting of the limiting plate 37 can ensure that the screw rods 36 rotate in the square tubes 32 to prevent the screw rods 36 from moving downward.

[0045] The bottom of the limiting plate 37 is rotatably connected to the top of the square tube 32 , and the bottom end of the screw rod 36 passes through the top of the square tube 32 and extends to the inside of the square rod 33 .

[0046] The outer surface of the screw rod 36 is threadedly connected to the inner surface of the square rod 33 . Two pulleys 38 are fixed on each of the five screw rods 36 . A vertical rod 39 is fixed on the top of the pinion gear 24 .

[0047] A pulley 38 is fixed to the top of the vertical rod 39, and adjacent pulleys 38 are connected by belts 310. The design of multiple pulleys 38 and belts 310 can ensure that the five screw rods 36 can rotate synchronously, thereby realizing the synchronous outward extension or retraction of the five cleaning plates 35 and bristles 35.

[0048] By setting up the mobile cleaning component 3, the dust and impurities around the robot body 1 can be quickly gathered and collected. At the same time, when the moving rod 27 drives the bristles 35 to extend outward, it can drive the bristles 35 to move upward without contacting the dust on the ground. This avoids the bristles 35 from driving the dust back and forth during the back and forth movement. The bristles 35 only contact the ground when they are retracted inward, and deep cleaning is performed close to the ground, which greatly improves the dust gathering efficiency. Moreover, it is uniformly controlled by the motor 25 on the telescopic adjustment mechanism 2, and the degree of automation is high.

[0049] Example 3

[0050] Based on Example 2, see Figure 1 , Figure 3 and Figure 8 As shown, five dust removal components 6 for cleaning the bristles 35 are arranged on the pentagonal plate 21. The dust removal components 6 include a transverse tube 61 fixed on the pentagonal plate 21, and one end of the transverse tube 61 is slidably connected to a transverse rod 62.

[0051] One end of the cross bar 62 extends to the inside of the cross tube 61, and an L-shaped rod 63 is fixed to one side of the cross bar 62. A side plate 64 is fixed to the bottom end of the L-shaped rod 63, and a cleaning fork 65 is fixed to one side of the side plate 64. When the bristles 35 move radially outward, they contact the cleaning fork 65. The cleaning fork 65 is a comb-like structure. After the bristles 35 contact it, the bristles 35 can scrape off dust and impurities when they move. When the cross bar 62 is stretched out, the cleaning fork 65 is located on one side of the bristles 35. After the cross bar 62 is pushed into the cross tube 61, the cleaning fork 65 is located at the bottom of the bristles 35 and contacts it.

[0052] By setting the dust removal component 6, the cleaning fork 65 is used to contact the bristles 35, so that when the bristles 35 extend and move outward, the dust and hair adhering to the bristles 35 are automatically scraped off by the cleaning fork 65, and there is no need to manually clean the bristles 35, and the cleaning efficiency is high.

[0053] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0054] When working, the insertion rod 4 on the telescopic adjustment mechanism 2 is inserted into the socket 5, and the motor 25 is started, so that the motor 25 drives the small gear 24 to rotate, and the small gear 24 drives the large gear 22 to rotate. When the large gear 22 rotates, it drives the arc groove 26 to rotate, and then drives the limit column 28 to move, and then drives the five moving rods 27 to extend and move outward, and then drives the mobile cleaning component 3 to move outward. During the movement, the small gear 24 drives the vertical rod 39 to rotate, and the vertical rod 39 drives the pulley 38 to rotate. Through the transmission cooperation between the belt 310 and each pulley 38, the five screw rods 36 are rotated, and then the five square rods 33 are driven to move upward along the inner surface of the square tube 32. When it is necessary to clean dust in a larger range, the sweeping robot is started and the motor is driven. 25 is reversed, thereby causing the mobile cleaning component 3 to retract and move inward, and at the same time, the motor 25 drives the five screw rods 36 to reverse, and the screw rods drive the five square rods 33, the cleaning plate 34, and the bristles 35 to move downward, so that the bristles 35 are in contact and squeezed with the ground, and the surrounding dust is gathered to the robot body 1, and then absorbed by the robot body 1. When it is necessary to clean the dust on the bristles 35, when the mobile cleaning component 3 extends and moves outward, the cross bar 62 is pushed to move the cross bar toward the inside of the cross tube 61, thereby driving the L-shaped rod 63, the side plate 64, and the cleaning fork 65 to move, and finally making the cleaning fork 65 move to the bottom of the bristles 35 and contact with it. At this time, when the bristles 35 are extending and moving outward, the cleaning fork 65 can be used to automatically scrape off and remove impurities such as dust and hair.

[0055] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and cannot be considered to limit the scope of the invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of the invention.
