[0037] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0038] Referring to Figure 1 and Figure 2 The embodiment of the present application provides a sweeping machine, which comprises a shell 1, a buffer structure 2 and a cleaning piece 3, the shell 1 has a first station 11 and a second station 12; the buffer structure 2 comprises a mounting component 21 and an elastic piece 22, the mounting component 21 is rotationally connected to the shell 1, the mounting component 21 can be selectively rotated to the first station 11 or the second station 12, the elastic piece 22 is elastically abutted to the shell 1 and the mounting component 21 respectively, and the elastic piece 22 is used to push the mounting component 21 to rotate to the first station 11; the cleaning piece 3 is rotationally connected to the mounting component 21, and when the mounting component 21 rotates between the first station 11 and the second station 12, the cleaning piece 3 is used to clean the ground.

[0039] In practical application, the shell 1 is provided with a rotating groove, the rotating groove comprises a first station 11 and a second station 12, the mounting component 21 is rotatably connected with the shell 1 and rotates in the rotating groove; when the sweeper works normally, the mounting component 21 rotates between the first station 11 and the second station 12, at the same time, the cleaning component 3 also starts to rotate for cleaning the ground; the elastic component 22 abuts between the mounting component 21 and the shell 1 along the advancing direction of the sweeper, the first station 11 can be arranged in front of the second station 12, when the mounting component 21 leaves the second station 12, the elastic component 22 is usually in a natural or pre-compressed state, at this time, the sweeper drives and the cleaning component 3 cleans the ground, when the sweeper drives to a lower obstacle, the shell 1 of the sweeper is higher than the obstacle, so the shell 1 can cross the obstacle, while the cleaning component 3 collides with the obstacle, the impact force generated by the collision is usually opposite to the advancing direction of the sweeper, so the impact force pushes the mounting component 21 to the direction close to the second station 12, since the mounting component 21 and the shell 1 form elastic contact through the elastic component 22, when the cleaning component 3 collides with the obstacle, under the action of the impact force, the mounting component 21 rotates to the direction away from the obstacle and compresses the elastic component 22, so that the mounting component 21 drives the cleaning component 3 to elastically avoid the obstacle, at the same time, the elastic component 22 converts the rigid contact into elastic contact, preventing the impact force from being transmitted to the shell 1 or the power parts inside the shell 1, causing the sweeper to malfunction and abnormal sound. The elastic component 22 can adopt a spring or a torsion spring, and the cleaning component 3 can adopt a cleaning brush.

[0040] It should be noted that the cleaning component 3 is usually located on the side of the shell 1 facing the ground, facilitating the cleaning of the ground, and the first station 11 should be closer to the side or the outer side of the shell 1 than the second station 12, so that when the mounting component 21 rotates from the first station 11 to the second station 12, the second station 12 is located inside the shell 1 and will not collide with the obstacle to a great extent.

[0041] It should be noted again that the rotation of the cleaning component 3 and the mounting component 21 is driven by different driving components.

[0042] Compared with the prior art, the present application sets the cleaning component 3 on the mounting component 21 by setting the mounting component 21 and the elastic component 22, and the mounting component 21 and the shell 1 form elastic connection through the elastic component 22, when the cleaning component 3 collides with the obstacle, the rigid collision is converted into elastic collision through the elastic action of the elastic component 22, thereby avoiding the collision damage to the cleaning component 3 and the shell 1, and avoiding the transmission of external force to the inside of the shell 1, causing the internal parts of the shell 1 to produce abnormal noise, protecting the power parts inside the shell 1.

[0043] Reference is made to Figure 2 and 3The mounting component 21 comprises a mounting base 211 and a fixing column 212 connected to the mounting base 211, the housing 1 is provided with a mounting hole 15, and the fixing column 212 is arranged in the mounting hole 15. The elastic member 22 is sleeved on the outer periphery of the fixing column 212 and connected to the housing 1.

[0044] In actual application, the fixing column 212 is inserted into the mounting hole 15 and can rotate in the mounting hole 15, and the elastic member 22 can be a torsion spring. The helical body of the torsion spring is sleeved on the outer periphery of the fixing column 212, and the torsion arm of the torsion spring is connected to the housing 1. When the mounting component 21 is located at the first station 11, the torsion spring is in a natural or pre-pressed state. When the cleaning member 3 collides with an obstacle and drives the mounting component 21 to rotate, the fixing column 212 rotates in the mounting hole 15, so that the helical body of the torsion spring rotates and accumulates elastic potential energy. When the cleaning member 3 moves away from the obstacle, the torsion spring releases the elastic potential energy and drives the mounting component 21 to rotate to the first station 11, facilitating the continuation of the cleaning work. The torsion spring buffers the impact force generated by the collision, avoids the transmission of the impact force to the housing 1, and has the advantages of simple installation, low cost, saving of design funds and good economy.

[0045] Referring to Figure 4 , Figure 5 and Figure 7 , the sweeping machine comprises a limiting structure 4, the limiting structure 4 comprises a limiting gear 41 and a first power member 42. The limiting gear 41 is sleeved on the outer periphery of the fixing column 212, and the limiting gear 41 is used for abutting against the fixing column 212 at the second station 12. The driving end of the first power member 42 is connected with the limiting gear 41 to limit the rotation of the limiting gear 41.

[0046] In actual application, the sweeper is working, the installation component 21 needs to reciprocate between the first station 11 and the second station 12, the rotating process is completed by the first power element 42 and the elastic element 22, specifically, in the initial state, if the installation component 21 is in the second station 12, the elastic element 22 is in the compressed state, therefore the elastic element 22 exerts the elastic force on the fixed column 212 to push the fixed column 212 to rotate to the direction of the first station 11, at this time, since the limiting gear 41 abuts against the fixed column 212, the rotation of the fixed column 212 is limited, therefore the installation component 21 can stably stay in the second station 12. When the sweeper starts to work, the first power element 42 rotates to the first direction, drives the limiting gear 41 to rotate to the preset angle, at this time, the limiting gear 41 is away from the fixed column 212, the elastic element 22 can push the fixed column 212 to rotate to the direction of the first station 11, when the fixed column 212 also rotates to the preset angle, the fixed column 212 abuts against the limiting gear 41 again, the fixed column 212 cannot rotate, at this time, the installation component 21 is just located in the first station 11 and abuts against the shell 1, since the resistance generated by the abutment of the installation component 21 and the shell 1 is too large, the circuit system senses the increase of the resistance and the current, therefore the circuit system controls the first power element 42 to reverse, the first power element 42 rotates to the second direction, drives the limiting gear 41 to rotate back, the limiting gear 41 rotates to the second station 12, in this process, the limiting gear 41 always abuts against the fixed column 212, therefore the limiting gear 41 pushes the fixed column 212 to rotate to the second station 12, the fixed column 212 drives the installation base 211 to rotate to the second station 12, at this time, the elastic element 22 is compressed, until the installation component 21 rotates to the second station 12, the installation component 21 abuts against the shell 1 again, the circuit system senses the increase of the resistance and the current, controls the first power element 42 to rotate to the first direction again, repeats the above process, and thus realizes the swing of the installation component 21 between the first station 11 and the second station 12, enhances the cleaning range and cleaning effect of the cleaning member 3.

[0047] It should be noted that the above-mentioned preset angle can be the rotating angle required for the second station 12 to rotate to the first station 11, the first power element 42 can adopt the structure of a worm motor, the worm motor has high precision and self-locking ability; the above-mentioned first direction refers to the direction of rotating from the second station 12 to the first station 11, and the second direction refers to the direction of first rotating from the first station 11 to the second station 12.

[0048] Again refer to Figure 7The limiting gear 41 comprises a gear portion 411 and a limiting ring 412, the limiting ring 412 is coaxially connected with the gear portion 411, the driving end of the first power member 42 is connected with the gear portion 411, the inner side of the limiting ring 412 is provided with a limiting block 413, the limiting groove 213 is formed in the circumferential direction of the fixed column 212, the limiting block 413 is located in the limiting groove 213, and the limiting block 413 is used for abutting against the fixed column 212 in the second working position 12.

[0049] In actual application, the limiting gear 41 mainly comprises the gear portion 411 and the limiting ring 412, the gear portion 411 and the limiting ring 412 are coaxially connected, the gear portion 411 can be connected with the driving end of the first power member 42 through a plurality of gears, the limiting ring 412 is internally provided with the limiting block 413, the limiting ring 412 is sleeved on the outside of the fixed column 212, and the limiting block 413 is located in the limiting groove 213 of the fixed column 212, when the sweeper is not working, the limiting block 413 abuts against the fixed column 212, so as to prevent the elastic member 22 from pushing the fixed column 212 to rotate, when the sweeper starts to work, the first power member 42 drives the gear portion 411 to rotate towards the first working position 11, the gear portion 411 drives the limiting ring 412 to rotate, at this time, the limiting block 413 is away from the fixed column 212, so that the elastic member 22 can push the fixed column 212 to rotate towards the first working position 11, until the mounting component 21 is located in the first working position 11, the fixed column 212 abuts against the limiting block 413 again, so as to avoid the mounting component 21 from rotating excessively, and facilitate the fixed column 212 to reverse to the second working position 12.

[0050] Again referring to Figure 4 and Figure 5 , the sweeper further comprises a driving component 5, the driving component 5 is connected with the cleaning member 3, and the driving component 5 is used for driving the cleaning member 3 to clean the ground.

[0051] In actual application, the cleaning member 3 cleans the ground by rotating, so that the bristles of the cleaning member 3 can gather the garbage on the ground to the center of the cleaning member 3, and the garbage is more easily sucked into the dust collecting box. Therefore, the driving component 5 is arranged, the output end of the driving component 5 is connected with the cleaning member 3, when the sweeper works, the driving component 5 drives the cleaning member 3 to rotate, so that the cleaning member 3 realizes the cleaning function.

[0052] Referring to Figure 5 and Figure 8 , the driving component 5 comprises a driving shaft 51, a driving wheel 52 and a second power member 53, the first end of the driving shaft 51 is connected with the driving end of the second power member 53, the second end of the driving shaft 51 extends into the mounting component 21 and is rotationally connected with the mounting component 21, the driving wheel 52 is rotationally connected in the mounting component 21 and is engaged with the second end of the driving shaft 51, and the cleaning member 3 is connected with the driving wheel 52.

[0053] In practical application, the driving shaft 51 has opposite first and second ends along its length direction, the first end is connected with the driving end of the second power member 53 through gear transmission, the second end extends through the fixing column 212 into the mounting base 211 and is rotationally connected with the mounting base 211, the driving wheel 52 is rotationally arranged in the mounting base 211 and is engaged with the second end of the driving shaft 51, thus, when the second power member 53 is started, the second power member 53 drives the driving shaft 51 to rotate, the driving shaft 51 drives the driving wheel 52 to rotate, the driving wheel 52 further drives the cleaning member 3 connected therewith to rotate, so as to realize the cleaning function of the cleaning member 3. At the same time, since the driving shaft 51 is rotationally matched with the mounting member 21, the mounting member 21 can rotate relative to the driving shaft 51, so that the mounting member 21 can drive the cleaning member 3 to swing back and forth, and the second power member 53 can also drive the cleaning member 3 to rotate, thereby enhancing the cleaning range and cleaning efficiency.

[0054] The second power member 53 can adopt a worm motor or the like structure, the worm motor has high precision and self-locking capability.

[0055] Referring to Figure 8 and Figure 9 , the driving member 5 further comprises a rotating screw 54, the rotating screw 54 is rotationally connected with the mounting member 21 and is arranged inside the driving wheel 52, the rotating screw 54 is threadedly connected with the driving wheel 52, and the cleaning member 3 is connected with the rotating screw 54.

[0056] In practical application, the cleaning member 3 can be lifted and rotated when the sweeper is working, and the height of the cleaning member 3 can be adjusted according to the height variation of the ground. When the sweeper moves from a hard ground (such as ceramic tile) to a soft ground (such as thick carpet), the cleaning member 3 can be lifted to ensure that appropriate pressure can be maintained on the ground of different heights for cleaning. If the height of the cleaning member 3 is fixed, when the cleaning member 3 encounters a higher ground such as carpet, the cleaning member 3 can not be able to contact the ground for cleaning, or the cleaning member 3 can be damaged due to excessive extrusion.

[0057] Based on this, the rotating screw 54 is arranged inside the driving wheel 52, the driving wheel 52 is internally provided with an internal thread, the rotating screw 54 is externally provided with an external thread matched with the internal thread, the rotating screw 54 is threadedly connected with the driving wheel 52, when the second power member 53 is started, the second power member 53 drives the driving shaft 51 to rotate, the driving shaft 51 drives the driving wheel 52 to rotate, the driving wheel 52 drives the rotating screw 54 to lift and rotate through thread connection, and further drives the cleaning member 3 to lift and rotate, so as to realize the height adjustment of the cleaning member 3.

[0058] Referring to Figure 9 and Figure 10The inner side of the driving wheel 52 is provided with a first abutting portion 521, and the outer side of the rotating screw 54 is provided with a second abutting portion 541. The first abutting portion 521 is used to abut with the second abutting portion 541 to push the rotating screw 54 to rotate together with the driving wheel 52.

[0059] In actual application, in order to facilitate the cleaning piece 3 to stably clean the ground without height adjustment, the inner side of the driving wheel 52 is connected with the first abutting portion 521, and the outer side of the rotating screw 54 is connected with the second abutting portion 541. When the driving wheel 52 drives the rotating screw 54 to rotate, the rotating screw 54 rotates relative to the driving wheel 52 and also lifts relative to the driving wheel 52. When the rotating screw 54 rotates to a preset position, the second abutting portion 541 abuts with the first abutting portion 521 at this position. If the driving wheel 52 continues to rotate, the first abutting portion 521 will push the second abutting portion 541 to rotate together, so as to make the rotating screw 54 and the driving wheel 52 rotate together, realize the stable cleaning function of the cleaning piece 3, and avoid the cleaning piece 3 to continue to lift, so as to affect the cleaning effect.

[0060] Again referring to Figure 2 and Figure 4 The shell 1 includes a bottom shell 13 and a fixing seat 14. The bottom shell 13 is provided with a rotating groove on the side facing the ground. The rotating groove has a first station 11 and a second station 12. The fixing seat 14 is connected to the bottom shell 13. The fixing seat 14 is provided with a through hole 141. The mounting component 21 at least partially extends into the through hole 141. The elastic piece 22 is elastically connected with the mounting component 21 and the fixing seat 14 respectively. The first station 11 is closer to the side of the bottom shell 13 than the second station 12.

[0061] In actual application, the fixing seat 14 is mainly used to fix the elastic piece 22. The fixing seat 14 and the bottom shell 13 can be detachably connected. The bottom shell 13 is provided with a mounting hole 15. The fixing seat 14 is provided with a through hole 141 corresponding to the mounting hole 15. The fixing column 212 of the mounting component 21 penetrates through the mounting hole 15 and the through hole 141. The spiral main body of the elastic piece 22 is sleeved on the outer side of the fixing column 212. The torsion arm of the elastic piece 22 is connected to the fixing seat 14. In this way, the elastic connection between the fixing column 212 and the fixing seat 14 can be realized. When the fixing column 212 rotates relative to the fixing seat 14, the elastic piece 22 can accumulate elastic potential energy.

[0062] And the first station 11 is closer to the side of the bottom shell 13 than the second station 12, so when the sweeper works, the installation base 211 rotates to the first station 11, and the cleaning piece 3 is closer to the side of the bottom shell 13, and in the process of rotating from the second station 12 to the first station 11, the cleaning piece 3 moves from the inside to the outside of the bottom shell 13, and the closer the cleaning piece 3 is to the outside, the greater the probability of collision between the cleaning piece 3 and the obstacle, and in this process, because the elastic piece 22 is in a natural or pre-compressed state, when the cleaning piece 3 collides with the obstacle, the elastic piece 22 can change the rigid contact into elastic contact, and buffer the impact force. Conversely, in the process of rotating from the first station 11 to the second station 12, because the second station 12 is located inside the bottom shell 13, in this process, the cleaning piece 3 will hardly touch the obstacle, so the possibility of collision with the obstacle is effectively avoided.

[0063] Referring to Figure 11 and Figure 12 The fixing seat 14 includes a first limiting portion 142 and a second limiting portion 143, the first limiting portion 142 abuts against the installation component 21 in the first station 11, and the second limiting portion 143 abuts against the installation component 21 in the second station 12.

[0064] In actual application, a limiting baffle can be arranged on the installation base 211, when the installation base 211 drives the cleaning piece 3 to rotate to the first station 11, the limiting baffle abuts against the first limiting portion 142, the first limiting portion 142 prevents the installation base 211 from continuing to rotate, so that the installation base 211 can accurately stay in the first station 11, avoiding inaccurate positioning of the installation base 211, and at the same time, the resistance generated by the abutment between the limiting baffle and the first limiting portion 142 is large, and the circuit system can sense the resistance, thereby controlling the first power piece 42 to rotate in the second direction; similarly, when the installation base 211 rotates to the second station 12, the limiting baffle abuts against the second limiting portion 143, the second limiting portion 143 prevents the installation base 211 from continuing to rotate, avoiding over-rotation of the installation base 211, which causes the elastic piece 22 to be excessively twisted and exceeds the elastic limit of itself, so that the elastic piece 22 loses elasticity and cannot play a buffering role, and at the same time, the resistance generated by the abutment between the limiting baffle and the second limiting portion 143 is large, and the circuit system can sense the resistance, thereby controlling the first power piece 42 to rotate in the first direction, and repeating the process, realizing the reciprocating rotation of the installation component 21 between the first station 11 and the second station 12.

[0065] Different from the prior art, the embodiment of the application provides a sweeping machine, which comprises a shell 1, a buffer structure 2 and a sweeping piece 3, the shell 1 has a first station 11 and a second station 12; the buffer structure 2 comprises a mounting component 21 and an elastic piece 22, the mounting component 21 is rotationally connected to the shell 1, the mounting component 21 can be selectively rotated to the first station 11 or the second station 12, the elastic piece 22 elastically abuts against the shell 1 and the mounting component 21 respectively, and the elastic piece 22 is used to push the mounting component 21 to rotate to the first station 11; the sweeping piece 3 is rotationally connected to the mounting component 21, and when the mounting component 21 rotates between the first station 11 and the second station 12, the sweeping piece 3 is used to sweep the ground. Compared with the prior art, the elastic piece 22 abuts between the mounting component 21 and the shell 1 respectively, when the mounting component 21 leaves the second station 12, the elastic piece 22 is generally in a natural or pre-compressed state, at this time, the sweeping machine travels, and the sweeping piece 3 sweeps the ground, when the sweeping piece 3 collides with an obstacle, the impact force generated by the collision is generally opposite to the advancing direction of the sweeping machine, so the impact force pushes the mounting component 21 to the direction close to the second station 12, because the mounting component 21 and the shell 1 form elastic contact through the elastic piece 22, when the sweeping piece 3 collides with the obstacle, under the action of the impact force, the mounting component 21 rotates to the direction away from the obstacle and compresses the elastic piece 22, so that the mounting component 21 drives the sweeping piece 3 to elastically avoid the obstacle, at the same time, the elastic piece 22 converts the rigid contact into the elastic contact, preventing the impact force from being transmitted to the shell 1 or the power parts inside the shell 1, causing the sweeping machine to malfunction. The application sets the mounting component 21 and the elastic piece 22, sets the sweeping piece 3 on the mounting component 21, and buffers the impact force of the collision through the elastic effect of the elastic piece 22, so as to avoid the collision from damaging the sweeping piece 3 and the shell 1, and also avoid the external force from being transmitted to the shell 1, causing the parts inside the shell 1 to produce abnormal noise.

[0066] The above is only the specific embodiment of the application, and it should be pointed out that, for ordinary skilled in the art, without departing from the principle of the application, a number of improvements and refinements can be made, and these improvements and refinements should be regarded as the protection range of the application.
