Description

Technical Field

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

[0002] With the acceleration of the modern life rhythm, people's demand for the automation of housework is increasing day by day. As an efficient and intelligent cleaning tool, the floor sweeping robot has been widely used in the field of household cleaning with its automatic operation and diverse cleaning functions. It can integrate multiple functions such as sweeping, vacuuming, and even mopping, greatly reducing the household burden of users and providing convenience for modern families.

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

[0004] When encountering larger garbage, the suction port of the existing equipment may be blocked. For example, when some floor sweeping robots encounter larger garbage, due to the limited size of the suction port, these large garbage may get stuck at the suction port, causing the equipment to malfunction and requiring manual cleaning to restore its function. Moreover, even if the large garbage does not completely block the suction port, it is difficult to be effectively adsorbed and stored due to its large volume. Summary of the Invention

[0005] The present invention provides a floor sweeping device to solve the above-mentioned existing technical problems.

[0006] The technical solution of the present invention is realized as follows:

[0007] A floor sweeping device includes a body, a dust suction device is provided at the bottom of the body. The dust suction device includes a cover body rotatably installed at the bottom of the body, and further includes a cleaning roller provided on one side of the cover body for driving the cover body to rotate. A plurality of arc-shaped grooves are formed on the outer wall of the cover body, threads for engaging in the arc-shaped grooves are provided outside the cleaning roller, and a plurality of through holes for external fine objects to pass through and communicating with the inner cavity of the cover body are formed on the bottom wall of the arc-shaped grooves.

[0008] Furthermore, the dust suction device includes a mounting seat for mounting the cover body. A first mounting groove is formed 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] Further, a second installation groove communicating with the first installation groove is also formed at the bottom of the body, and the cleaning roller is rotatably installed at the communicating part of the first installation groove and the second installation groove.

[0010] Further, 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.

[0011] Further, a connecting groove is formed in the first installation groove. The cover body is hemispherical, and a connecting strip slidably connected to the connecting groove is provided at one end edge 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 the same as the cross-sectional shape of the connecting groove.

[0012] Further, motor seats and installation parts are respectively arranged on both sides of the bottom of the body near the communicating part of the first installation groove and the second installation 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 installation part.

[0013] Further, a motor groove is also formed in the mounting seat, and an impeller groove communicating with the motor groove is also formed. A high-speed motor is installed in the motor groove, and a high-speed impeller accommodated in the impeller groove is connected to the transmission end of the high-speed motor. A plurality of air outlet holes communicating with the impeller groove are also formed in the mounting seat, and an air flow channel communicating with the impeller groove is formed in the first installation groove.

[0014] Further, a filtering component is also installed on the first installation groove. The filtering component is cylindrical, and the opening of the filtering component is installed in the first installation groove and communicates with the air flow channel.

[0015] Further, a collection box is detachably installed in the second installation groove. A collection port for external objects to pass through is formed in the collection box, and the collection port is arranged at the communicating part of the first installation groove and the second installation groove.

[0016] Further, wheels and universal wheels are also movably installed at the bottom of the body, and a rotary brush is also installed. The wheels are symmetrically arranged on both sides of the bottom of the body, and the rotary brush is symmetrically arranged at the bottom of the body near the edge part.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, a dust suction device is provided at the bottom of the machine body. By installing a rotatable cover body with a number of through holes as the dust suction inlet, dust and garbage on the ground can be adsorbed. Fine garbage or dust passes through the through holes and is collected into the cover body, while larger objects cannot enter the cover body and are adsorbed in the arc-shaped groove on the cover body. The continuously rotating cleaning roller linked to the cover body sweeps the objects in the arc-shaped groove and brings them into the collection box for collecting garbage objects, thereby achieving preliminary regional storage of objects of different sizes, avoiding the mixed accumulation of garbage in the dust collection space, and effectively solving the problems of waste of the dust collection space and difficult cleaning caused by the mixture of fine dust and large garbage in traditional dust suction devices;

[0019] Through the regional storage design, fine dust and large garbage are stored separately, avoiding the problems of difficult cleaning and reduced dust suction efficiency caused by garbage mixture in traditional devices. Fine dust can smoothly enter the interior of the cover body through the through holes, while large garbage is swept by the cleaning roller into the collection box, ensuring the high efficiency and thoroughness of the cleaning process; The regional storage design enables users to more conveniently clean the garbage in the collection box, without frequently cleaning the dust suction port or the entanglements on the cleaning components, reducing the frequency and difficulty of manual cleaning by users, lowering the usage complexity, and improving the user experience. The linkage structure between the cover body and the cleaning roller reduces the risk of blockage of large garbage at the dust suction port, avoids equipment failures caused by blockage of large garbage, extends the service life of the equipment, and reduces the maintenance and replacement costs.

[0028] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1-6 shown, a floor cleaning device includes a body 1, a dust suction device 2 is provided at the bottom of the body 1, the dust suction device 2 includes a cover body 21 rotatably mounted at the bottom of the body 1, and further includes a cleaning roller 22 for driving the cover body 21 to rotate, which is arranged on one side of the cover body 21. A plurality of arc grooves 24 are formed on the outer wall of the cover body 21, and threads 23 for engaging in the arc grooves 24 are arranged outside the cleaning roller 22. A plurality of through holes 25 for allowing external small objects to pass through and communicating with the inner cavity of the cover body 21 are formed on the bottom wall of the arc groove 24.

[0030] In this embodiment, the core component of the dust suction device 2 is the rotatable cover body 21, and the cover body 21 is installed at the bottom of the body 1. A plurality of arc grooves 24 are formed on the outer wall of the cover body 21, and these arc grooves 24 are used to adsorb larger garbage. A plurality of through holes 25 are also formed on the bottom wall of the arc grooves 24 of the cover body 21, and these through holes 25 communicate with the inner cavity of the cover body 21, so that small garbage or dust can be received into the interior of the cover body 21 through these through holes 25;

[0031] A cleaning roller 22 is arranged on one side of the cover body 21, and threads 23 are arranged on the outer wall of the cleaning roller 22. These threads 23 can be engaged in the arc grooves 24 on the outer wall of the cover body 21. When the cleaning roller 22 rotates, the engagement of the threads 23 and the arc grooves 24 drives the cover body 21 to rotate together, so that the cleaning roller 22 can effectively clean the large garbage adsorbed in the arc grooves 24 and bring it into the collection box 15.

[0032] Further, the dust suction device 2 includes a mounting base 26 for mounting the cover body 21. A first mounting groove 27 is formed in the mounting base 26, and the cover body 21 is rotatably connected in the first mounting groove 27. A plurality of bristles are provided on the inner wall of the first mounting groove 27.

[0033] The plurality of bristles provided on the inner wall of the first mounting groove 27 can further comb the garbage when the cover body 21 rotates, preventing the garbage from accumulating on the surface of the cover body 21.

[0034] Further, a second mounting groove 3 communicating with the first mounting groove 27 is also formed at the bottom of the body 1, and the cleaning roller 22 is rotatably mounted at the communicating portion of the first mounting groove 27 and the second mounting groove 3.

[0035] Further, a plurality of bristles are provided on the outer wall of the thread 23. The thread 23 is engaged with the arc-shaped groove 24. When the cleaning roller 22 rotates, the thread 23 engaged in the arc-shaped groove 24 drives the cover body 21 to rotate.

[0036] 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, preventing the garbage from staying on the cover body 21, and at the same time can better clean the garbage out of the arc-shaped groove 24.

[0037] Further, a connecting groove 271 is formed in the first mounting groove 27. The cover body 21 is hemispherical. A connecting strip 4 slidably connected in 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 the same as the cross-sectional shape of the connecting groove 271.

[0038] 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-shaped groove 24. The sliding of the connecting strip 4 in the connecting groove 271 ensures the smooth rotation of the cover body 21;

[0039] 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 clamped in the first mounting groove 27 without falling off. In some embodiments, the connecting strip 4 portion of the cover body 21 has a certain elasticity, and the cover body 21 can be forcibly removed from the first mounting groove 27.

[0040] Further, a motor base 5 and a mounting portion 6 are respectively provided on both sides of the bottom of the body 1 near the communicating portion of 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 base 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.

[0041] Further, a motor slot 8 is also formed on the mounting base 26, and an impeller slot 9 communicating with the motor slot 8 is further formed. A high-speed motor 10 is installed in the motor slot 8, a high-speed impeller 11 accommodated in the impeller slot 9 is connected to the transmission end of the high-speed motor 10, a plurality of air outlet holes 12 communicating with the impeller slot 9 are further formed on the mounting base 26, and an air flow channel 13 communicating with the impeller slot 9 is formed in the first mounting slot 27.

[0042] The high-speed motor 10 is installed in the motor slot 8 of the mounting base 26. When the sweeping device is started, the high-speed motor 10 starts to work. 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 surroundings, forming a negative pressure area. The mounting base 26 is provided with air flow channels 13 communicating with 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 generated negative pressure is transmitted to the inside of the cover body 21 through the air flow channels 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 holes 25, and fine dust and garbage are sucked into the inside of the cover body 21 through the through holes 25, thereby collecting the dust and garbage in the cover body 21.

[0043] Further, a filtering component 14 is also installed on the first mounting slot 27. The filtering component 14 is in a cylindrical shape, and the opening of the filtering component 14 is installed in the first mounting slot 27 and communicates with the air flow channel 13.

[0044] In one embodiment, the filtering component 14 is a deformable filter screen, which has a certain extensibility and can be manually adjusted to change into various states. When dust and garbage enter from the outside of the cover body 21 through the through holes 25, they will be intercepted by the filtering component 14 and retained in the cover body 21;

[0045] The inside of the filtering component 14 is filled with high-efficiency filtering materials, which can effectively capture and filter dust, fine particles and impurities in the air. The filtered air becomes clean, reducing the pollution to the motor and other internal components and extending the service life of the equipment.

[0046] Further, a collection box 15 is detachably installed in the second mounting slot 3. The collection box 15 is provided with a collection port 16 for external objects to pass through, and the collection port 16 is arranged at the communication position between the first mounting slot 27 and the second mounting slot 3.

[0047] Furthermore, wheels 17 and omnidirectional wheels 18 are movably installed at the bottom of the body 1, and a rotary brush 19 is also installed. The wheels 17 are symmetrically arranged on both sides of the bottom of the body 1, and the rotary brush 19 is symmetrically arranged at the bottom of the body 1 near the edge.

[0048] The rotary brush 19 is used to clean the dust and garbage in the edge area. The ground garbage is swept by the rotary brush 19 and moved under the dust collection device 2.

[0049] When the sweeping device is started, the wheels 17 and the omnidirectional wheels 18 drive the device to move on the ground. At the same time, the drive motor 7 and the high-speed motor 10 start to work. The drive motor 7 drives the cleaning roller 22 to rotate through the connection. The thread 23 of the cleaning roller 22 engages with the arc-shaped groove 24 of the cover body 21, driving the cover body 21 to rotate. The bristles on the cleaning roller 22 sweep out the large garbage adsorbed in the arc-shaped 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 to form a negative pressure area, and sucking the fine dust and garbage into the interior of the cover body 21 through the air flow channel 13. The filtering component 14 intercepts and filters the dust and impurities in the air to ensure the cleanliness of the discharged air. The rotary 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.

[0050] The present invention realizes efficient cleaning and garbage classification through a unique structural design. The arc-shaped groove 24 and the through hole 25 of the cover body 21 separate the treatment of large garbage and fine garbage. The rotation of the cleaning roller 22 drives the rotation of the cover body 21 to ensure that the large garbage is swept by the cleaning roller 22 and sent into the collection box 15. The negative pressure generated by the high-speed impeller 11 sucks the fine garbage into the interior of the cover body 21 through the air flow channel 13. The filtering component 14 further filters the air to prevent dust from entering components such as the motor, extending the service life of the equipment. The design of the rotary brush 19 and the wheels 17 improves the cleaning range and movement flexibility, ensuring comprehensive cleaning of the ground.

[0051] The specific embodiments of the invention have been described in detail above, but they are only examples. The present invention is not limited to the specific embodiments described above. Those skilled in the art of this industry should understand that the above embodiments and the descriptions in the specification only illustrate the principle of the present invention.
