Description

Technical Field

[0001] The invention relates to the technical field of household cleaning equipment, in particular to a sweeping device. Background Art

[0002] As the pace of modern life accelerates, people's demand for automated housework is growing. As an efficient and intelligent cleaning tool, sweeping robots have been widely used in the field of household cleaning due to their automated operation and diverse cleaning functions. They can integrate multiple functions such as sweeping, vacuuming and even mopping, greatly reducing the user's housework burden and providing convenience for modern families.

[0003] Traditional sweeping robots usually have only one collection method, which is to suck dust and garbage directly into the dust bag or dust box through the suction port. This design does not distinguish between objects of different sizes, resulting in mixed accumulation of garbage in the dust bag or dust box. For example, fine dust and larger garbage (such as paper balls, small toy parts, etc.) are mixed together, which not only easily wastes dust collection space, but also makes it difficult to completely clean up the fine dust, because the large garbage will hinder the normal operation of the suction port and reduce the dust collection efficiency.

[0004] When encountering large garbage, the suction port of existing equipment may be blocked. For example, when some sweeping robots encounter large garbage, due to the limited size of the suction port, these large garbage may be stuck in the suction port, causing the equipment to not work properly and need to be manually cleaned to restore function. Moreover, even if the large garbage does not completely block the suction port, it will be difficult to be effectively absorbed and stored due to its large size. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, the present invention provides a sweeping device.

[0006] The technical solution of the present invention is achieved in this way: A sweeping device comprises a body, a dust collecting device is arranged at the bottom of the body, the dust collecting device comprises a cover body rotatably mounted at the bottom of the body, and also comprises a cleaning roller arranged on one side of the cover body for driving the cover body to rotate, the outer wall of the cover body is provided with a plurality of arc grooves, the cleaning roller is provided with a thread for engaging in the arc grooves, and the bottom wall of the arc groove is provided with a plurality of through holes connected to the inner cavity of the cover body for passing small external objects.

[0007] Furthermore, the dust collecting device includes a mounting seat for mounting a cover body, a first mounting groove is provided on the mounting seat, the cover body is rotatably connected in the first mounting groove, and a plurality of bristles are provided on the inner wall of the first mounting groove.

[0009] Furthermore, a plurality of bristles are provided on the outer wall of the thread, and the thread is engaged with the arc-shaped groove. When the cleaning roller rotates, the thread engaged in the arc-shaped groove drives the cover body to rotate.

[0010] Furthermore, a connecting groove is provided in the first mounting groove, the cover body is hemispherical, and a connecting strip slidably connected to the connecting groove is provided at the edge of one end of the cover body. The width of the connecting strip is greater than the wall thickness of the cover body, and the cross-sectional shape of the connecting strip is consistent with the cross-sectional shape of the connecting groove.

[0011] Furthermore, a motor seat and a mounting portion are respectively provided on both sides of the bottom of the body near the connection between the first mounting groove and the second mounting groove. A driving motor for driving the cleaning roller to rotate is installed in the motor seat. One end of the cleaning roller is connected to the driving motor, and the other end is inserted into the mounting portion.

[0012] Furthermore, the mounting seat is provided with a motor slot and an impeller slot connected to the motor slot. A high-speed motor is installed in the motor slot.

[0020] like Figure 1-6 As shown, a sweeping device includes a body 1, a dust collecting device 2 is arranged at the bottom of the body 1, the dust collecting device 2 includes a cover body 21 rotatably installed at the bottom of the body 1, and also includes a cleaning roller 22 arranged on one side of the cover body 21 for driving the cover body 21 to rotate, the outer wall of the cover body 21 is provided with a plurality of arc grooves 24, the cleaning roller 22 is provided with a thread 23 for engaging in the arc groove 24, and the bottom wall of the arc groove 24 is provided with a plurality of through holes 25 connected to the inner cavity of the cover body 21 for passing small external objects.

[0021] In this embodiment, the core component of the dust collecting device 2 is a rotatable cover 21, which is installed at the bottom of the machine body 1. A plurality of arc-shaped grooves 24 are provided on the outer wall of the cover 21, and these arc-shaped grooves 24 are used to absorb large garbage. A plurality of through holes 25 are also provided on the bottom wall of the arc-shaped grooves 24 of the cover 21, and these through holes 25 are connected to the inner cavity of the cover 21, so that small garbage or dust can be collected into the cover 21 through these through holes 25; A cleaning roller 22 is provided on one side of the cover body 21, and a thread 23 is provided on the outer wall of the cleaning roller 22. These threads 23 can be engaged in the arc groove 24 on the outer wall of the cover body 21. When the cleaning roller 22 rotates, the engagement of the thread 23 and the arc groove 24 drives the cover body 21 to rotate together, so that the cleaning roller 22 can effectively clean out the large garbage adsorbed in the arc groove 24 and bring it into the collection box 15.

[0022] Furthermore, the dust collecting device 2 includes a mounting seat 26 for mounting the cover body 21 , a first mounting groove 27 is formed on the mounting seat 26 , the cover body 21 is rotatably connected in the first mounting groove 27 , and a plurality of bristles are arranged on the inner wall of the first mounting groove 27 .

[0023] The plurality of bristles disposed on the inner wall of the first mounting groove 27 can further comb out the garbage when the cover body 21 rotates, thereby preventing the garbage from accumulating on the surface of the cover body 21 .

[0024] Furthermore, a second mounting groove 3 communicating with the first mounting groove 27 is formed at the bottom of the machine body 1 , and the cleaning roller 22 is rotatably mounted at the communicating portion between the first mounting groove 27 and the second mounting groove 3 .

[0025] Furthermore, a plurality of bristles are disposed on the outer wall of the thread 23 , and the thread 23 is engaged with the arc groove 24 . When the cleaning roller 22 rotates, the thread 23 engaged in the arc groove 24 drives the cover body 21 to rotate.

[0026] In order to further improve the cleaning effect, bristles are also provided on the outer wall of the thread 23 of the cleaning roller 22. These bristles can play a combing role during the cleaning process to prevent garbage from staying on the cover body 21, and can also better clean the garbage out of the arc groove 24.

[0027] Furthermore, a connecting groove 271 is provided in the first mounting groove 27, the cover body 21 is hemispherical, and a connecting strip 4 slidably connected to the connecting groove 271 is provided at one end edge of the cover body 21, the width of the connecting strip 4 is greater than the wall thickness of the cover body 21, and the cross-sectional shape of the connecting strip 4 is consistent with the cross-sectional shape of the connecting groove 271.

[0028] The cooperation between the connecting strip 4 and the connecting groove 271 not only provides the installation position of the cover body 21, but also provides support for the rotation of the cover body 21. When the cleaning roller 22 rotates, the cover body 21 is driven to rotate by the engagement of the thread 23 and the arc groove 24. The sliding of the connecting strip 4 in the connecting groove 271 ensures the stability of the rotation of the cover body 21. The width of the connecting strip 4 is greater than the wall thickness of the cover body 21, so that the cover body 21 can be snapped into the first mounting groove 27 without falling off. In some embodiments, the connecting strip 4 of the cover body 21 has a certain elasticity, and the cover body 21 can be removed from the first mounting groove 27 by force.

[0029] Furthermore, a motor seat 5 and a mounting portion 6 are respectively provided on both sides of the bottom of the body 1 near the connection between the first mounting groove 27 and the second mounting groove 3. A driving motor 7 for driving the cleaning roller 22 to rotate is installed in the motor seat 5. One end of the cleaning roller 22 is connected to the driving motor 7, and the other end is inserted into the mounting portion 6.

[0030] Furthermore, the mounting seat 26 is provided with a motor slot 8, and an impeller slot 9 connected to the motor slot 8. A high-speed motor 10 is installed in the motor slot 8, and a transmission end of the high-speed motor 10 is connected to a high-speed impeller 11 accommodated in the impeller slot 9. The mounting seat 26 is provided with a plurality of air outlet holes 12 connected to the impeller slot 9, and the first mounting slot 27 is provided with an air flow channel 13 connected to the impeller slot 9.

[0031] The high-speed motor 10 is installed in the motor slot 8 of the mounting seat 26. When the sweeping device is started, the high-speed motor 10 starts to work, and the rotational power of the motor is transmitted to the high-speed impeller 11 through the transmission end. The rotation of the high-speed impeller 11 generates a strong centrifugal force in the impeller slot 9, which throws the air from the center of the impeller slot 9 to the surrounding areas, forming a negative pressure area. The mounting seat 26 is provided with an air flow channel 13 connected to the impeller slot 9. These air flow channels 13 connect the negative pressure area in the impeller slot 9 with the inside of the cover body 21. When the high-speed impeller 11 rotates, the negative pressure generated is transmitted to the inside of the cover body 21 through the air flow channel 13, forming a strong suction force. The negative pressure inside the cover body 21 extends to the outer wall of the cover body 21 through the through hole 25, and fine dust and garbage are sucked into the cover body 21 through the through hole 25, so that the dust and garbage are stored in the cover body 21.

[0032] Furthermore, a filter component 14 is installed on the first installation groove 27 . The filter component 14 is cylindrical. The opening of the filter component 14 is installed in the first installation groove 27 and communicates with the air flow channel 13 .

[0033] In one embodiment, the filter component 14 is a deformable filter screen, which has a certain degree of ductility and can be manually adjusted to change into various states. When dust and garbage enter the interior of the cover body 21 through the through hole 25, they will be intercepted by the filter component 14 and retained in the cover body 21. The filter component 14 is internally filled with high-efficiency filter materials, which can effectively capture and filter dust, fine particles and impurities in the air. The filtered air becomes clean, reducing pollution to the motor and other internal components, and extending the service life of the equipment.

[0034] Furthermore, a collection box 15 is detachably installed in the second installation groove 3 , and a collection port 16 for external objects to pass through is opened on the collection box 15 , and the collection port 16 is arranged at the connection point between the first installation groove 27 and the second installation groove 3 .

[0035] Furthermore, wheels 17 and universal wheels 18 are movably installed at the bottom of the body 1, and a rotating brush 19 is also installed. The wheels 17 are symmetrically arranged on both sides of the bottom of the body 1, and the rotating brush 19 is symmetrically arranged near the edge of the bottom of the body 1.

[0036] The rotating brush 19 is used to clean the dust and garbage in the edge area. The rotating brush 19 sweeps the garbage on the ground and moves it to the bottom of the dust suction device 2.

[0037] When the sweeping device is started, the wheels 17 and the universal wheels 18 drive the device to move on the ground, and at the same time, the drive motor 7 and the high-speed motor 10 start working. The drive motor 7 connects to the cleaning roller 22 to make it rotate, and the thread 23 of the cleaning roller 22 engages with the arc groove 24 of the cover body 21 to drive the cover body 21 to rotate. The bristles on the cleaning roller 22 will sweep out the large garbage adsorbed in the arc groove 24 and send it into the collection box 15 through the air flow channel 13. The high-speed motor 10 drives the high-speed impeller 11 to rotate, generating a strong centrifugal force, forming a negative pressure area, and sucking fine dust and garbage into the cover body 21 through the air flow channel 13. The filter component 14 intercepts and filters dust and impurities in the air to ensure that the discharged air is clean. The rotating brush 19 sweeps the garbage at the edge to the cleaning roller 22 and the cover body 21, expanding the cleaning range and improving the cleaning efficiency; The present invention achieves efficient cleaning and garbage classification through a unique structural design. The arc groove 24 and the through hole 25 of the cover body 21 separate large garbage and small garbage for processing. The rotation of the cleaning roller 22 drives the cover body 21 to rotate, ensuring that the large garbage is cleaned by the cleaning roller 22 and then sent to the collection box 15. The negative pressure generated by the high-speed impeller 11 sucks the small garbage into the cover body 21 through the air flow channel 13. The filter component 14 further filters the air to prevent dust from entering the motor and other components, thereby extending the service life of the equipment. The design of the rotating brush 19 and the wheel 17 improves the cleaning range and mobility, ensuring comprehensive cleaning of the ground.
