[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In addition, some of the above terms may be used to express other meanings in addition to indicating a direction or position relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] See also Figure 1 and Figure 2 The embodiment of the present application provides a sweeping machine, including a shell 1, a buffer structure 2 and a cleaning member 3, the shell 1 has a first station 11 and a second station 12; the buffer structure 2 includes a mounting component 21 and an elastic member 22, the mounting component 21 is rotatably 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 member 22 elastically abuts the shell 1 and the mounting component 21 respectively, and the elastic member 22 is used to push the mounting component 21 to rotate to the first station 11; the cleaning member 3 is rotatably 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 member 3 is used to clean the floor.

[0039] In actual application, the shell 1 is provided with a rotation groove, which includes a first station 11 and a second station 12. The mounting component 21 is rotationally connected to the shell 1 and rotates in the rotation groove; when the sweeper is working normally, the mounting component 21 rotates between the first station 11 and the second station 12, and at the same time, the cleaning component 3 also starts to rotate to clean the ground; the elastic component 22 is respectively abutted between the mounting component 21 and the shell 1. Along the forward direction of the sweeper, the first station 11 can be set 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-tightened state. At this time, the sweeper is moving while the cleaning component 3 is cleaning the ground. When the sweeper moves to a lower obstacle, the sweeper The shell 1 is higher than the obstacle, so the shell 1 can go over the obstacle, and the cleaning part 3 just collides with the obstacle. The direction of the impact force generated by the collision is usually opposite to the forward direction of the sweeper, so the impact force pushes the installation component 21 in the direction close to the second station 12. Since the installation component 21 and the shell 1 form an elastic contact through the elastic member 22, when the cleaning part 3 collides with the obstacle, under the action of the collision force, the installation component 21 rotates in the direction away from the obstacle and compresses the elastic member 22, so that the installation component 21 drives the cleaning part 3 to elastically avoid the obstacle. At the same time, the elastic member 22 converts the rigid contact into an elastic contact to prevent the impact force from being transmitted to the shell 1 or the power parts inside the shell 1, causing the sweeper to malfunction and make abnormal noises. Among them, the elastic member 22 can be a spring or a torsion spring, and the cleaning part 3 can be a cleaning brush or other structure.

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

[0041] It should be noted again that the rotation of the cleaning member 3 and the mounting member 21 are driven by different driving members respectively.

[0042] Compared with the prior art, the present application arranges the cleaning part 3 on the mounting part 21 by setting the mounting part 21 and the elastic part 22. At the same time, the mounting part 21 and the shell 1 are elastically connected through the elastic part 22. When the cleaning part 3 collides with an obstacle, the elastic action of the elastic part 22 converts the rigid collision into an elastic collision, thereby avoiding damage to the cleaning part 3 and the shell 1 due to the collision, and also avoiding external force from being transmitted to the shell 1, causing abnormal noise from the internal parts of the shell 1, thereby protecting the internal power parts of the shell 1.

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

[0044] In actual application, the fixed column 212 is inserted into the mounting hole 15 and can rotate in the mounting hole 15. The elastic member 22 can be a torsion spring. The spiral body of the torsion spring is sleeved on the outer periphery of the fixed column 212. 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-compressed state. When the cleaning component 3 encounters an obstacle and drives the mounting component 21 to rotate, the fixed column 212 rotates in the mounting hole 15, so that the spiral body of the torsion spring rotates to accumulate elastic potential energy. When the cleaning component 3 is away from the obstacle, the torsion spring releases the elastic potential energy and pushes the mounting component 21 to rotate toward the first station 11, so as to facilitate the continuation of the cleaning work. The torsion spring buffers the impact force generated by the collision to prevent the impact force from being transmitted to the housing 1. In addition, the torsion spring is simple to install, has a low cost, saves design funds, and has good economy.

[0045] See also Figure 4 , Figure 5 and Figure 7 The sweeper includes a limiting structure 4, which includes a limiting gear 41 and a first power member 42. The limiting gear 41 is sleeved on the outer periphery of the fixed column 212. The limiting gear 41 is used to abut against the fixed column 212 in the second workstation 12. The driving end of the first power member 42 is connected to the limiting gear 41 to limit the rotation of the limiting gear 41.

[0046] In actual application, when the sweeper is working, the installation component 21 needs to reciprocate between the first station 11 and the second station 12. This rotation process is completed by the first power member 42 and the elastic member 22. Specifically, in the initial state, if the installation component 21 is in the second station 12, the elastic member 22 is in a compressed state, so the elastic member 22 applies elastic force to the fixed column 212 to push the fixed column 212 to rotate in 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 restricted. Therefore, the fixed column 212 cannot rotate, and the installation component 21 can stay stably in the second station 12. When the sweeper starts working, the first power piece 42 rotates in the first direction, driving the limit gear 41 to rotate to a preset angle. At this time, the limit gear 41 is away from the fixed column 212, and the elastic member 22 can push the fixed column 212 to rotate in the direction of the first station 11. When the fixed column 212 also rotates by the preset angle, the fixed column 212 abuts against the limit gear 41 again, and the fixed column 212 cannot rotate. At this time, the mounting component 21 is just located at the first station 11 and abuts against the shell 1. Since the resistance generated by the abutment between the mounting component 21 and the shell 1 is too large, the circuit system senses that the resistance and current increase here, so the circuit system controls the first power piece 42 to reverse, and the first power piece 42 rotates in the second direction, driving The movable limit gear 41 rotates, and the limit gear 41 rotates toward the second station 12. During this process, the limit gear 41 is always in contact with the fixed column 212, so the limit gear 41 pushes the fixed column 212 to rotate toward the second station 12, and the fixed column 212 drives the mounting base 211 to rotate toward the second station 12. At this time, the elastic member 22 is compressed until the mounting component 21 rotates to the second station 12, and the mounting component 21 is again in contact with the shell 1. The circuit system senses the increase in resistance and current, and controls the first power member 42 to rotate in the first direction again, and repeats the above process, thereby realizing the mounting component 21 to swing back and forth between the first station 11 and the second station 12, thereby enhancing 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 rotation angle required for the second station 12 to rotate to the first station 11, and the first power member 42 can adopt a structure such as a worm motor, which has high precision and self-locking capability; the above-mentioned first direction refers to: the direction of rotation from the second station 12 to the first station 11, and the second direction refers to: the direction of rotation from the first station 11 to the second station 12 first.

[0048] See again Figure 7The limiting gear 41 includes a gear portion 411 and a limiting ring 412. The limiting ring 412 is coaxially connected to the gear portion 411. The driving end of the first power member 42 is connected to the gear portion 411. A limiting block 413 is provided on the inner side of the limiting ring 412. The fixed column 212 is provided with a limiting groove 213 along its circumference. The limiting block 413 is located in the limiting groove 213, and the limiting block 413 is used to abut against the fixed column 212 in the second workstation 12.

[0049] In practical applications, the limiting gear 41 is mainly composed of a gear portion 411 and a limiting ring 412. The gear portion 411 and the limiting ring 412 are coaxially connected. The gear portion 411 can be connected to the driving end of the first power member 42 through a plurality of gears. A limiting block 413 is provided inside the limiting ring 412. 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 to prevent the elastic member 22 from pushing the fixed column 21 2 rotation, when the sweeper starts to work, the first power member 42 drives the gear part 411 to rotate in the direction of the first station 11, and the gear part 411 drives the limit ring 412 to rotate. At this time, the limit block 413 is away from the fixed column 212, so that the elastic member 22 can push the fixed column 212 to rotate in the direction of the first station 11, until the installation component 21 is located in the first station 11, the fixed column 212 is again in contact with the limit block 413 to prevent the installation component 21 from rotating excessively, and at the same time facilitate the fixed column 212 to reverse back to the second station 12.

[0050] See again Figure 4 and Figure 5 The sweeping machine further includes a driving component 5, which is connected to the cleaning component 3 and is used to drive the cleaning component 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, making it easier to suck the garbage into the dust box. Therefore, the present application provides a driving member 5, the output end of which is connected to the cleaning member 3. When the sweeper is working, the driving member 5 drives the cleaning member 3 to rotate, so that the cleaning member 3 can achieve the cleaning function.

[0052] See also Figure 5 and Figure 8 The driving component 5 includes a driving shaft 51, a driving wheel 52 and a second power member 53. The first end of the driving shaft 51 is connected to the driving end of the second power member 53. The second end of the driving shaft 51 extends into the mounting component 21 and rotates with the mounting component 21. The driving wheel 52 is rotatably connected to the mounting component 21 and meshes with the second end of the driving shaft 51. The cleaning component 3 is connected to the driving wheel 52.

[0053] In practical applications, the driving shaft 51 has a first end and a second end opposite to each other along its length direction, wherein the first end is connected to the driving end of the second power member 53 through gear transmission, and the second end is passed through the fixing column 212 and extends into the mounting base 211, and is rotationally connected to the mounting base 211, and the driving wheel 52 is rotationally arranged in the mounting base 211 and meshes with the second end of the driving shaft 51, so that 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, and the driving wheel 52 further drives the cleaning member 3 connected thereto to rotate, thereby realizing the cleaning function of the cleaning member 3. At the same time, since the driving shaft 51 and the mounting component 21 are rotationally matched, the mounting component 21 can rotate relative to the driving shaft 51, so that the second power member 53 can also drive the cleaning member 3 to rotate while the mounting component 21 drives the cleaning member 3 to swing back and forth, thereby enhancing the cleaning range and cleaning efficiency.

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

[0055] See also Figure 8 and Fig. 9 The driving component 5 also includes a rotating screw 54, which is rotatably connected to the mounting component 21 and is disposed inside the driving wheel 52. The rotating screw 54 is threadedly connected to the driving wheel 52, and the cleaning member 3 is connected to the rotating screw 54.

[0056] In actual applications, when the sweeper is working, the cleaning member 3 can be lifted and rotated, and the height of the cleaning member 3 can be adjusted according to the height of the ground. When the sweeper moves from a hard ground (such as tiles) to a soft ground (such as thick carpet), the cleaning member 3 can be raised to ensure that appropriate pressure can be maintained for cleaning on the ground at different heights. If the cleaning member 3 is at a fixed height, when encountering a higher ground such as a carpet, it may not be able to clean because it cannot contact the ground, or the cleaning member 3 may be damaged due to excessive squeezing.

[0057] Based on this, the present application provides a rotating screw 54, which is arranged in the driving wheel 52. The driving wheel 52 is provided with an internal thread inside, and the rotating screw 54 is provided with an external thread matching it outside. 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, and the driving shaft 51 drives the driving wheel 52 to rotate. The driving wheel 52 drives the rotating screw 54 to rise and fall and rotate through the threaded connection, thereby driving the cleaning member 3 to rise and fall and rotate, thereby realizing the function of adjusting the height of the cleaning member 3.

[0058] See also Fig. 9 and Fig.10A first abutting portion 521 is provided on the inner side of the driving wheel 52 , and a second abutting portion 541 is provided on the outer side of the rotating screw 54 . The first abutting portion 521 is used to abut against 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 member 3 to stably clean the ground without adjusting the height, a first abutment portion 521 is connected to the inner side of the driving wheel 52, and a second abutment portion 541 is connected to the outer side of the rotating screw 54. When the driving wheel 52 drives the rotating screw 54 to rotate, the rotating screw 54 rotates relative to the driving wheel 52 while also rising and falling relative to the driving wheel 52. When the rotating screw 54 rotates to a preset position, at this position, the second abutment portion 541 abuts against the first abutment portion 521. If the driving wheel 52 continues to rotate, the first abutment portion 521 will push the second abutment portion 541 to rotate together, thereby causing the rotating screw 54 and the driving wheel 52 to rotate together, thereby realizing the stable cleaning function of the cleaning member 3 and preventing the cleaning member 3 from continuing to rise and fall, thereby affecting the cleaning effect.

[0060] See again 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 rotation groove on one side facing the ground. The rotation 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 member 22 is elastically connected to 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 applications, the fixing seat 14 is mainly used to fix the elastic member 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, and 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 passes through the mounting hole 15 and the through hole 141. The spiral body of the elastic member 22 is sleeved on the outside of the fixing column 212, and the torsion arm of the elastic member 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 member 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 that when the sweeper is working, after the mounting base 211 is rotated to the first station 11, the cleaning member 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 member 3 moves from the inside to the outside of the bottom shell 13, and the closer the cleaning member 3 is to the outside, the greater the probability of the cleaning member 3 colliding with an obstacle, and in this process, since the elastic member 22 is in a natural or pre-compression state, when the cleaning member 3 collides with an obstacle, the elastic member 22 can convert the rigid contact into elastic contact to buffer the impact force of the collision, conversely, in the process of rotating from the first station 11 to the second station 12, since the second station 12 is located inside the bottom shell 13, in this process, the cleaning member 3 will hardly touch the obstacle, thereby effectively avoiding the possibility of colliding with the obstacle.

[0063] See also Fig.11 and Fig.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 mounting component 21 at the first station 11 , and the second limiting portion 143 abuts against the mounting component 21 at the second station 12 .

[0064] In practical applications, a limit baffle can be provided on the mounting base 211. When the mounting base 211 drives the cleaning member 3 to rotate to the first station 11, the limit baffle abuts against the first limit portion 142. The first limit portion 142 prevents the mounting base 211 from continuing to rotate, so that the mounting base 211 can accurately stay in the first station 11, avoiding inaccurate positioning of the mounting base 211. At the same time, the resistance generated by the abutment of the limit baffle and the first limit portion 142 is relatively large, and the circuit system can sense the resistance here, thereby controlling the first power member 42 to rotate in the second direction. Similarly, when the mounting base 211 rotates When the second station 12 is reached, the limit baffle abuts against the second limit part 143 again. The second limit part 143 prevents the mounting base 211 from continuing to rotate, thereby preventing the mounting base 211 from rotating excessively, causing the elastic member 22 to twist excessively, exceeding its own elastic limit, causing the elastic member 22 to lose its elasticity and fail to play a buffering role. At the same time, the resistance generated by the abutment of the limit baffle and the second limit part 143 is relatively large. The circuit system can sense the resistance here, thereby controlling the first power member 42 to rotate in the first direction, and repeating this process to achieve the reciprocating rotation of the mounting component 21 between the first station 11 and the second station 12.

[0065] Different from the prior art, the embodiment of the present application provides a sweeping machine, including 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 includes a mounting component 21 and an elastic component 22, the mounting component 21 is rotatably 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 component 22 elastically abuts the shell 1 and the mounting component 21 respectively, and the elastic component 22 is used to push the mounting component 21 to rotate to the first station 11; the cleaning piece 3 is rotatably 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 floor. Compared with the prior art, the elastic member 22 is respectively abutted between the mounting member 21 and the shell 1. When the mounting member 21 leaves the second station 12, the elastic member 22 is usually in a natural or pre-tightened state. At this time, the sweeper is traveling while the cleaning member 3 is cleaning the ground. When the cleaning member 3 collides with an obstacle, the direction of the impact force generated by the collision is usually opposite to the forward direction of the sweeper. Therefore, the impact force pushes the mounting member 21 toward the second station 12. Since the mounting member 21 and the shell 1 form elastic contact through the elastic member 22, when the cleaning member 3 collides with the obstacle, under the action of the collision force, the mounting member 21 rotates away from the obstacle and compresses the elastic member 22. In this way, the mounting member 21 drives the cleaning member 3 to elastically avoid the obstacle. At the same time, the elastic member 22 converts the rigid contact into elastic contact to prevent the impact force from being transmitted to the shell 1 or the power parts inside the shell 1, causing the sweeper to malfunction. The present application arranges the cleaning component 3 on the mounting component 21 by providing the mounting component 21 and the elastic component 22. The elastic effect of the elastic component 22 can buffer the impact force of the collision, thereby avoiding damage to the cleaning component 3 and the shell 1 due to the collision, and also avoiding the external force from being transmitted to the shell 1, causing abnormal noise from the internal parts of the shell 1.

[0066] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
