[0002] The present application relates to the technical field of cleaning equipment, in particular to a cleaning equipment. BACKGROUND

[0003] The existing cleaning robots on the market are generally equipped with sealing strips only at the rear and both sides of the dust suction port. The disadvantage of this structure is that the front part of the dust suction port is not sealed, which greatly reduces the vacuum degree of the dust collector, and some difficult-to-clean dust will accumulate in the dust suction port and the dust suction channel, resulting in poor dust suction effect.

[0004] Therefore, CN203244345U provides a cleaning robot, which is provided with a dynamic sealing element in front of the dust suction port, and the up-down translation of the dynamic sealing element is realized by driving the chain wheel through a motor. This design improves the dust suction effect by providing a dynamic sealing element and a matching motor for the cleaning robot, and the up-down translation of the dynamic sealing element improves the dust suction effect. As a result, additional motor requirements are brought, and production costs are increased. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0031] The preferred embodiments of the present application will be described in detail with reference to the drawings, so that the advantages and features of the present application can be more easily understood by those skilled in the art, and the scope of protection of the present application can be more clearly defined. The following embodiments can be appropriately combined with each other. Identical reference numerals and symbols in the drawings and different embodiments in the description are used to represent the same or equivalent elements.

[0032] Referring to Figure 5 , the cleaning device 3 provided by the embodiments of the present application includes a main body 31, a movement assembly 32 arranged on the main body 31, and a dust collection assembly 1 arranged on the main body 31. The cleaning device 3 can be a sweeping robot, a handheld sweeper, a handheld dust collector, a bucket-type dust collector, a horizontal dust collector, a vertical dust collector, or other devices with a dust collection structure, which are not listed here.

[0033] Referring to Figure 1 , Figure 3 and Figure 5 , the dust collection assembly 1 is used to perform cleaning work on the to-be-cleaned, and in an embodiment of the present application, the dust collection assembly 1 includes a housing 10 formed with a cavity 100, a cleaning roller 101 arranged in the cavity 100, and a sealing member 20 arranged on at least one side of the cleaning roller 101.

[0034] The dust suction assembly 1 is movable between a raised position and a working position. When the dust suction assembly 1 performs cleaning work on the surface to be cleaned, the dust suction assembly 1 is in the working position, at which the cleaning roller 101 contacts the surface to be cleaned, and the cleaning roller 101 is driven to rotate by the motor 231 to suck dust and other garbage into a dust storage device (not shown) provided on the main body 31 under the action of a fan assembly (not shown) provided on the main body 31. When the cleaning device 3 needs to cross an obstacle, the dust suction assembly 1 is in the raised position, and the cleaning roller 101 is away from the surface to be cleaned, thereby improving the obstacle-crossing ability and passability of the cleaning device 3.

[0035] The sealing member 20 can be provided on at least one of the front side, the rear side, the left side, and the right side of the cleaning roller 101. The cleaning roller 101 can be provided with one or two, and when the cleaning roller 101 is provided with two, the two cleaning rollers 101 are arranged in front of and behind the moving direction of the main body 31. When the sealing member 20 is provided on the front side, it is located on the front side of the front cleaning roller 101, and when the sealing member 20 is provided on the rear side, it is located on the rear side of the rear cleaning roller 101. In the present embodiment, the sealing member 20 is provided on at least one side of the housing 10, specifically, the sealing member 20 is provided on the front side of the housing 10. In other applications, the sealing member can be provided on the rear side of the housing or other sides, which is not specifically limited in the present embodiment. The sealing member 20 can be a piece of elastic plastic or a hard injection molding, and its length can cover the front side of the dust suction assembly 1 or only cover part of the front side.

[0036] The sealing member 20 is movable between a sealing position and an open position. When the dust suction assembly 1 performs cleaning work on the surface to be cleaned, the sealing member 20 is in the sealing position, that is, the free end of the sealing member 20 is close to the surface to be cleaned, so as to improve the sealing performance between the dust suction assembly 101 and the surface to be cleaned and improve the dust suction ability of the cleaning device 3. When the sealing member 20 is in the open position, the free end of the sealing member 20 is far away from the surface to be cleaned, so as to improve the ability of the cleaning device 3 to suck large-particle garbage on the surface to be cleaned.

[0037] The cleaning device 3 further comprises a driving structure provided on at least one of the main body 31 and the housing 10, which is configured to selectively drive the dust suction assembly 1 to move between the raised position and the working position and drive the sealing member 20 to move between the sealing position and the open position. The cleaning device of the present application can selectively drive the position adjustment of the sealing member 20 and the height adjustment of the dust suction assembly 1 with one driving structure without additional driving, so as to meet the adjustment requirements of the dust suction ability of the dust suction assembly under different cleaning states while reducing the cost of additional driving structures.

[0038] When the distance between the suction assembly 1 and the surface to be cleaned increases (from the working position to the lifting position), that is, when the suction assembly 1 is lifted, the suction assembly 1 does not need to perform the suction work at this time, and there is no requirement for the sealing performance between the suction assembly 1 and the surface to be cleaned. At this time, the driving structure drives the lifting of the suction assembly 1, and when the suction assembly 1 is attached to the surface to be cleaned to perform the suction work, the suction assembly 1 does not need to be lifted, and the driving structure is used to drive the sealing element 20 to ensure the suction capacity of the suction assembly 1 to the surface to be cleaned and improve the efficiency. That is, the lifting of the suction assembly 1 and the lifting of the sealing element 20 do not need to be performed at the same time, and one driving structure can selectively drive to meet the requirements.

[0039] The driving structure includes a driving source 13 and a switching mechanism 14 connected with the driving source 13, and the switching mechanism 14 is used to connect or disconnect the first transmission path or the second transmission path. Under the action of the switching mechanism 14, the first transmission path and the second transmission path in the suction assembly 1 are selectively connected. In the first transmission path connection state, the position of the sealing element 20 relative to the side surface can be adjusted, that is, the driving source 13 provides power to drive the sealing element 20 to move between the sealing position and the opening position. In the second transmission path connection state, the distance between the suction assembly 1 and the surface to be cleaned can be adjusted, that is, the driving source 13 provides power to drive the suction assembly to move between the lifting position and the working position. The cleaning equipment 3 of the embodiment of the present application coordinates the power requirements of the adjustment of the sealing performance of the suction assembly 1 and the height adjustment of the suction assembly 1 by setting the driving source 13 in a time-sharing selective connection mode, so as to meet the adjustment requirements of the suction capacity of the suction assembly 1 in different cleaning states while reducing the cost investment of the additional driving source 13.

[0040] In an embodiment, the driving source 13 includes a power output end (for example, an output shaft is provided), and the driving source 13 inputs power to the first transmission path or the second transmission path in a time-sharing selective connection mode. In the case of connecting the first transmission path, the sealing performance between the suction assembly 1 and the surface to be cleaned is adjusted, and in the case of connecting the second transmission path, the distance between the suction assembly 1 and the surface to be cleaned is adjusted. In other embodiments, the driving source includes a motor, a reduction box connected with the motor, and an output shaft connected with the output end of the reduction box. Or the driving source includes a motor, a transmission assembly connected with the motor shaft, and an output shaft connected with the output end of the transmission assembly. The transmission assembly can be a gear set and the like. The specific structure of the driving source is not specifically limited here.

[0041] The distance between the dust collection assembly 1 and the surface to be cleaned can be adjusted, at least including the height of the dust collection assembly 1 from the surface to be cleaned can be adjusted, to realize the lifting or lowering of the position of the dust collection assembly 1 relative to the surface to be cleaned. The sealing between the dust collection assembly 1 and the surface to be cleaned can be adjusted, at least including the adjustment of the shape of the ground end of the side of the dust collection assembly 1 where the sealing element 20 is located, or the adjustment of the distance between the ground end of the side of the dust collection assembly 1 where the sealing element 20 is located and the surface to be cleaned.

[0042] It can be understood that the surface to be cleaned in the embodiments of the present application represents the working surface in the environment where the dust collection assembly 1 is cleaning, for example, the cleanable ground, desktop, etc., and the material of the working surface is not limited to a certain kind, for example, it can be a soft carpet, or a hard floor, a wooden floor, etc. The moving assembly 32 supports the main body 31 and is used to drive the main body 31 to move on the surface to be cleaned. The moving assembly 32 includes two drive wheels 321 located on both sides of the middle part of the main body 31, and a passive wheel 322 located at the front end of the main body 31. The two drive wheels 321 can be independently driven by the power module, and such a setting can control the driving speed and direction of the cleaning device 3 by controlling the speed and speed difference of the two drive wheels 321, so that the walking and turning of the cleaning device 3 are flexible and accurate. The passive wheel 322 can be a universal wheel or other supporting wheel that supports, further improving the turning flexibility of the cleaning device. In other embodiments, the drive wheels can be arranged at the rear end of the fuselage, and the passive wheels are arranged at the front end. The moving assembly 32 can have other forms, such as a caterpillar type, etc.

[0043] The cleaning roller 101 can adopt a sweeping type cleaning roller (such as a rolling brush) with a brush structure or a roller type cleaning roller (such as a roller) that adsorbs the surface foreign matter of the surface to be cleaned by contact. The cleaning roller 101 can also be other types that realize the cleaning function through rotational motion relative to the surface to be cleaned, which is not limited in the embodiments of the present application.

[0044] In the embodiments of the present application, the first transmission path and the second transmission path are selectively connected. Regardless of which path is connected, the first transmission path and the second transmission path can affect the dust collection state of the dust collection assembly 1. Specifically, in the first transmission path connection state, the position or form of the sealing member 20 relative to the side surface can be adjusted, and in the second transmission path connection state, the distance between the housing 10 and the cleaning surface can be adjusted. The adjustment can be direct control or indirect control. The purpose is to generate a force acting on the sealing member 20 or the housing 10 through control, and to adjust the boundary of the dust collection assembly 1 relative to the cleaning surface and the height of the dust collection assembly 1 relative to the cleaning surface under the action of the force. In an exemplary application, the ground end of the sealing member 20 can have different shapes. For example, the sealing member 20 can be provided with a toothed structure. Further, the spacing between the toothed structures, the structure of the toothed structures, etc. can be provided. Thus, the adjustment of the position or form of the sealing member 20 can affect the ability of the dust collection assembly 1 to collect particles such as garbage during the dust collection process.

[0045] In one embodiment, the driving source 13 is configured to at least drive the switching mechanism 14 to move between the first engagement position and the second engagement position. When the switching mechanism 14 is located in the first engagement position, the first transmission path is connected. When the switching mechanism 14 is located in the second engagement position, the second transmission path is connected. Obviously, the first engagement position and the second engagement position are two different positions. The switching mechanism 14 is selectively located in the first engagement position or the second engagement position to selectively connect the first transmission path or the second transmission path. Selective connection can be understood as connecting the first transmission path in a set part of the period and connecting the second transmission path in a selected different period. In other words, under the action of the clutch mechanism, the periods when the first transmission path and the second transmission path are connected do not overlap.

[0046] In one embodiment, the switching mechanism 14 is a clutch mechanism. When the clutch mechanism is in the first engagement position, it is in the engaged state, and the first transmission path is connected at this time. When the clutch mechanism is in the second engagement position, it is in the disengaged state, and the second transmission path is connected at this time. In another embodiment, the clutch mechanism can be configured to connect the first transmission path in the disengaged state, and connect the second transmission path in the engaged state. The specific structure of the switching mechanism is not specifically limited, which will be described in detail later.

[0047] The dust collection assembly 1 will be described in detail in the specific embodiments below.

[0048] Please refer to Figure 1 , Figure 3 and Figure 4In addition to the above structure, the dust suction assembly 1 is provided with a dust suction channel 11, the dust suction assembly 1 is communicated with the dust storage device on the cleaning device 3 through the dust suction channel 11, so as to allow the dust suction airflow to collect the garbage gathered from the dust suction assembly 1 into the dust storage device. In the dust suction assembly 1, the front side edge of the shell 10 is provided with a sealing piece 20, the sealing piece 20 is provided with a tooth-shaped structure, and the sealing piece 20 extends on the transverse side of the dust suction assembly 1. The sealing piece 20 can be a sheet-shaped elastic plastic piece, or a hard injection molded piece, and the length thereof can cover the front side of the dust suction assembly 1 or only cover part of the front side.

[0049] In the embodiment, the switching mechanism 14 is a clutch mechanism. Specifically, the switching mechanism 14 includes a clutch tooth 142 arranged on the output shaft of the driving source 13, and an adjusting gear 16 engaged with the clutch tooth 142. The clutch tooth 142 is arranged on the output shaft in an axially movable manner, that is, the clutch tooth 142 and the output shaft rotate synchronously, and the clutch tooth 142 can move along the axial direction of the output shaft to realize the engagement or disengagement of the clutch tooth 142 and the adjusting gear 16. The adjusting gear 16 and the output shaft have no interaction force. In the embodiment, the adjusting gear 16 is arranged on the output shaft in an axially limited manner to realize synchronous rotation of the adjusting gear 16 and the clutch tooth 14. One side of the adjusting gear 16 is engaged with the clutch tooth 142, and the other side is abutted against the shell 10.

[0050] The driving source 13 includes a motor and a speed reduction mechanism, the motor shaft of the motor is connected with the input end of the speed reduction mechanism, and the intermediate shaft 131 of the speed reduction mechanism is connected with the transmission shaft 19 through the shaft coupling 18. That is, the output shaft of the driving source 13 includes the synchronously rotating intermediate shaft 131 and the transmission shaft 19, the output shaft is arranged as two shafts connected through the shaft coupling 18 to meet the length requirement. In other embodiments, the driving source 13 can also not be provided with the speed reduction mechanism, and the power output by the motor is transmitted to the transmission shaft 19 through the shaft coupling 18. The shaft coupling 18 serves as a connecting piece to realize the connection between the transmission shaft 19 and the output shaft of the driving source, and transmit the power output by the motor to the transmission shaft 19.

[0051] The clutch gear 142 and adjusting gear 16 of the switching mechanism 14 are mounted on the intermediate shaft 131. One end of the adjusting gear 16 abuts against the housing 10, and the other end is close to the clutch gear 142. The clutch gear 142 is positioned closer to the coupling 18 than the adjusting gear 16. When the switching mechanism 14 is in the first engagement position, the adjusting gear 16 and the clutch gear 142 are engaged and rotate synchronously with the output shaft. When the switching mechanism 14 is in the second engagement position, the adjusting gear 16 and the clutch gear 142 are disengaged. To achieve the engagement of the adjusting gear 16 and the clutch gear 142, the switching mechanism 14 also includes an elastic element 141 disposed between the clutch gear 142 and the output shaft. When the clutch gear 142 and the adjusting gear 16 are disengaged, the elastic element 141 deforms to drive the clutch gear 142 back to the engagement position with the adjusting gear 16 and store energy. Specifically, the elastic element 141 is disposed between the clutch gear 142 and the coupling 18. The elastic element 141 is a spring sleeved on the intermediate shaft 131, and the elastic element 141 always drives the clutch gear 142 and the adjusting gear 16 to mesh. In other embodiments, the elastic element 141 may also be a spring sheet or other structure. The engagement or disengagement of the adjusting gear and the clutch gear can also be achieved by a power component, and no specific limitation is made here.

[0052] A first transmission mechanism 15 connects the adjusting gear 16 and the seal 20. The adjusting gear 16 is configured to drive the seal 20 to move via the first transmission mechanism 15. The first transmission mechanism 15 can be a gear set. In this disclosure, to save on the structure of the dust collection assembly 1 and facilitate layout, the first transmission mechanism 15 is a gear portion 201 disposed on the seal 20 and cooperating with the adjusting gear 16. The connection between the adjusting gear 16 and the seal 20 is achieved through the meshing of the adjusting gear 16 and the gear portion 201. The adjusting gear 16 is configured to drive the seal 20 to move upward or downward through its rotation. It is understood that... Figure 1 As shown in the diagram, the two rotation directions of the adjusting gear 16 correspond to the upward or downward movement of the sealing member 20, thereby moving its free end away from or towards the surface to be cleaned, thus adjusting the different suction states of the vacuuming assembly 1. It can be understood that when the sealing member 20 moves upward, its near-ground end moves away from the surface to be cleaned, thereby increasing the ability of particles to converge towards the vacuuming assembly 1 through the boundary during vacuuming. Conversely, when the sealing member 20 moves downward, its near-ground end gradually moves closer to the surface to be cleaned, thus increasing the sealing performance between the vacuuming assembly 1 and the surface to be cleaned during vacuuming, improving the ability to remove foreign objects.

[0053] In order to realize the separation between the adjusting gear 16 and the clutch tooth 142, the housing 10 is provided with a limiting piece 202, which is abutted by the sealing piece 20 after the sealing piece 20 moves upward by a certain distance, and the limiting piece 202 blocks the continuous upward movement of the sealing piece 20. The adjusting gear 16 engaged with the sealing piece 20 stops rotating, while the intermediate shaft 131 and the transmission shaft 19 drive the clutch tooth 142 to continue rotating, and the clutch tooth 142 moves axially away from the adjusting gear 16, and the elastic piece 141 is compressed. The engagement state of the clutch tooth 142 and the adjusting gear 16 is changed to a separation state, and the switching mechanism 14 moves from the first engagement position to the second engagement position. When the driving source 13 stops or starts to reverse, the clutch tooth 142 moves towards the adjusting gear 16 under the action of the elastic piece 141 and engages with the adjusting gear 16. When the driving source 13 reverses, the intermediate shaft 131 and the transmission shaft 19 rotate reversely, the clutch tooth 142 drives the adjusting gear 16 to rotate reversely, and the sealing piece 20 moves downward until the free end (low end) of the sealing piece 20 abuts against the surface to be cleaned, and cannot continue to move downward, so that the adjusting gear 16 stops rotating. Similarly, the engagement state of the clutch tooth 142 and the adjusting gear 16 is changed to a separation state, and the switching mechanism 14 moves from the first engagement position to the second engagement position. It is easily conceivable that if the sealing piece 20 is not intended to move downward to abut against the surface to be cleaned, a blocking piece (not shown) can be provided on the housing 10, and when the sealing piece 20 abuts against the blocking piece, the position thereof is such that the sealing property of the dust collection assembly 1 meets the user's demand.

[0054] In order to ensure the stability of the movement of the sealing piece 20, the switching mechanism 14 is provided with two, which include a switching mechanism 14a and a switching mechanism 14b. The switching mechanism 14a and the switching mechanism 14b are oppositely arranged on both sides of the sealing piece 20, and the adjusting gears 16 in the switching mechanism 14a and the switching mechanism 14b rotate synchronously to realize the upward and downward movement of the sealing piece 20. The number of the switching mechanisms 14 is not limited to two, and in other embodiments, more or fewer switching mechanisms can also be provided, as long as the demand for path switching can be met.

[0055] It should be noted that the elastic piece 141 of the switching mechanism 14b is arranged between the second transmission mechanism (see below) and the clutch tooth 142, and the adjusting gear 16 is arranged between the clutch tooth 142 and the housing 10.

[0056] Specifically, in the embodiment, the front side edge of the dust collection assembly 1 is provided with a sealing piece 20, the sealing piece 20 extends on the lateral side of the dust collection assembly 1, and two groups of switching mechanisms (14a, 14b) are distributed at the two ends of the output shaft. The driving source 13 can be a driving force generated by a motor, which can act on a transmission path for controlling the sealing piece 20 and a transmission path for controlling the floating movement of the dust collection assembly 1. The output end of the motor is connected with the input end of the speed reducer, the intermediate shaft 131 at the output end of the speed reducer is connected with the coupling 18, and the coupling 18 is connected with the transmission shaft 19. In an embodiment, the driving source 13 is provided with a driving force by the motor, and in the working state of the motor, the sealing piece 20 is driven by the clutch tooth 142 to engage the adjusting gear 16 within a selected time, so as to realize the switching of the state of the ground to the upward away from the cleaning surface or the downward close to the cleaning surface. It can be understood that the cleaning surface can be the surface of different ground media such as soft or hard, and the switching of the state of the ground is not limited to the switching of the state of the hard ground, but can be the switching of the state of different types of cleaning surfaces. For example, when the cleaning surface is a soft carpet, the state of the ground of the sealing piece 20 can be close to or away from the surface of the carpet. The sealing piece 20 can be a piece of elastic plastic, or a hard injection molding, and the length thereof can cover the front side of the dust collection assembly, or only cover part of the front side. Figure 1 and Figure 4 In the embodiment, the sealing piece 20 is located on the front side of the shell 10 (which can also be described as the sealing piece 20 is located on one edge of the dust collection assembly 1, and adjusts the state of the ground of the dust collection assembly 1). In addition, the sealing piece 20 can have various forms, such as a toothed edge or a neat edge formed at the free end thereof. The different positions of the sealing piece 20 on the front side edge of the dust collection assembly 1 correspond to different performances of the vacuum degree and the garbage particle passability of the dust collection assembly 1, so that the position of the sealing piece 20 can adjust the different dust collection states of the dust collection assembly 1, adapt to more cleaning scenes, and obtain better cleaning effect. In another embodiment, the sealing piece 20 can also be located on the remaining side of the shell 10. The front side is taken as an example in the embodiment of the application, and does not constitute the only limitation on the adjustment of the boundary of the sealing piece 20 to the shell 10. For example, the sealing piece 20 can also be located on one or more other sides of the shell.

[0057] The second transmission mechanism 12 is connected between the switching mechanism 14 and the shell 10, and includes a traction frame 120 arranged on the main body 31 of the cleaning device 3, a traction rope 122 sliding through the traction frame 120, one end of the traction rope 122 being connected to the output shaft, and the other end being connected to the shell 10. When the switching mechanism 14 is in the second engagement position, the traction rope 122 is configured to be tightened or loosened under the rotation of the output shaft to pull the shell 10 to move. It should be noted that when the dust collection assembly 1 is installed on the main body 31 of the cleaning device 3, the distance of the dust collection assembly 1 relative to the cleaning surface can be adjusted, and the up-down movement of the dust collection assembly 1, that is, the up-down movement of the dust collection assembly 1.

[0058] In order to reasonably arrange, the traction rope 122 is connected to the transmission shaft 19. In this embodiment, in order to ensure the smoothness of the traction rope 122 being tightened or loosened under the rotation of the transmission shaft 19, the second transmission mechanism 12 further includes a pulley 121, the pulley 121 is sleeved and fixed on the transmission shaft 19, the traction rope 122 is connected to the pulley 121, the pulley 121 is driven to rotate by the transmission shaft 19, and the pulley 121 drives the traction rope 122 to elongate or shorten. The traction rope 122 is tightened or loosened under the driving of the rotation of the transmission shaft 19, and the traction frame 120 is fixed on the main body 31, so that the shell 10 of the dust collection assembly 1 is pulled away from or approaches the cleaning surface under the traction of the traction rope 122, thereby realizing the adjustment of the height of the dust collection assembly 1 relative to the cleaning surface.

[0059] It should be noted that when the switching mechanism 14 is in the first engagement position, the transmission shaft 19 drives the pulley 121 to rotate, and the traction rope 122 is tightened or loosened, but the traction rope 122 is provided with a margin, and the tightening or loosening of the traction rope 122 will not pull the up-down movement of the shell 10. Only when the switching mechanism 14 is in the second engagement position, the tightening or loosening of the traction rope 122 will pull the up-down movement of the shell 10, that is, the second transmission path is communicated.

[0060] The switching of the transmission path in the dust collection assembly 1 can include the following working states:

[0061] Working state 1: The ground end of the sealing element 20 (which can also be referred to as the free end of the sealing element 20) is away from the cleaning surface (the traction rope 122 is in the maximum margin state), and the dust collection assembly 1 approaches the cleaning surface;

[0062] Working state 2: the output shaft of the driving source 13 rotates in the first direction to drive the intermediate shaft 131 and the transmission shaft 19 to rotate, the adjusting gear 16 is in engagement with two clutch teeth 142 in two switching mechanisms (14a, 14b), the adjusting gear 16 rotates under the drive of the transmission shaft 19, and the sealing element 20 is lowered to approach the surface to be cleaned (in this process, the slack of the traction rope 122 is gradually occupied, and the suction assembly 1 remains close to the surface to be cleaned, and this working state is the state of the suction assembly 1 for dust collection);

[0063] Working state 3: the sealing element 20 is lowered to approach the surface to be cleaned, and the slack of the traction rope 122 approaches 0;

[0064] Working state 4: when the sealing element 20 abuts against the surface to be cleaned or the blocking element, the sealing element 20 and the adjusting gear 16 stop moving, the slack of the traction rope 122 becomes 0, the transmission shaft 19 continues to rotate, two clutch teeth 142 in two clutch mechanisms (14a, 14b) arranged at both ends of the transmission shaft 19 are disengaged from the adjusting gear 16, that is, the switching mechanism moves to the second engagement position, and the boundary adjusting structure 20 remains in the state of abutting against or approaching the surface to be cleaned, while the rotation of the transmission shaft 19 drives the pulley 121 to continue to tighten the traction rope 122, and the tightening of the traction rope 122 drives the shell 10 to move upward to the expected position / set state of the suction assembly 1;

[0065] Working state 5: the output shaft of the motor in the driving source 13 reverses, two clutch teeth 142 in two clutch mechanisms (14a, 14b) arranged at both ends of the transmission shaft are engaged with the adjusting gear 16, and the clutch mechanisms (14a, 14b) are in the engaged state, so that the sealing element 20 is driven by the adjusting gear 16 to move away from the surface to be cleaned, and the shell 10 moves downward under the action of the slack of the traction rope 122;

[0066] Working state 6: the shell 10 is lowered to the expected / set state close to the surface to be cleaned, and the sealing element 20 is in the state of moving away from the surface to be cleaned, when the suction assembly 1 is lowered to the expected position / set state, the transmission shaft 19 continues to rotate under the drive of the motor (in this process, the slack of the traction rope 122 is gradually generated); until the slack of the traction rope 122 is in the maximum slack state, facilitating the subsequent switching of the transmission path.

[0067] It should be noted that each working state in the above process can be continuously or intermittently executed, and based on the switching of the above different working states, the cleaning device 3 only uses a single driving source 13 in the suction assembly 1 to meet the floating movement requirements of the suction assembly 1 close to or away from the surface to be cleaned, and the power requirements of the sealing element 20 close to or away from the surface to be cleaned.

[0068] The dust collection assembly 1 can be controlled to switch to the working state 1 when the cleaning device 3 is adsorbing large-particle garbage on the surface to be cleaned; and the dust collection assembly can be controlled to switch to the working state 2 when a larger negative pressure is needed to adsorb the garbage on the surface to be cleaned. When the surface to be cleaned is a carpet surface, the dust collection assembly is in the working state 1, which improves the effect of gathering large-particle garbage to the dust collection assembly, and the dust collection assembly is in the working state 2, which improves the collection effect of fine dust and particles on the carpet surface.

[0069] In this embodiment, the dust collection assembly 1 is floatingly installed on the main body 31. By arranging a guide structure between the shell 10 and the main body 31, the floating movement of the dust collection assembly 1 can be guided in a predetermined track or direction. Figure 1 The shell 10 of the dust collection assembly 1 shown in the figure loads the cleaning rollers 101 to generate the expected floating movement effect of the dust collection assembly 1 in a predetermined track or direction. It can be understood that, since the dust collection channel 11 is connected to the dust storage device installed on the main body 31, a negative pressure channel is formed between the dust collection assembly 1 and the dust storage device. In order to maintain the necessary vacuum effect and take into account the floating movement effect of the dust collection assembly 1, at least a part of the negative pressure channel is configured to coordinate the movement requirements of other parts of the dust collection assembly 1 by elastic deformation.

[0070] Further, Figure 3 In addition to Figure 1 The shell 10 of the dust collection assembly shown in the figure, and the two cleaning rollers 101 installed in the shell 10. Figure 3 The motor 231 is also shown in the figure, which drives the two cleaning rollers 101 to rotate. It can be understood that, since the two cleaning rollers 101 are installed in the shell 10, when the shell 10 is connected to the second transmission path, the height of the shell 10 relative to the surface to be cleaned can be adjusted, so that the shell 10 can move away from or approach the opening of the surface to be cleaned (the opening of the cavity 100 towards the surface to be cleaned), and synchronously drive the two cleaning rollers 101 to approach or move away from the surface to be cleaned (the floating movement of the dust collection assembly 1 described in the foregoing). The cleaning device 3 with the foregoing dust collection assembly 1 can adapt to the height of the surface to be cleaned through the floating movement of the dust collection assembly 1, and correspondingly move away from the surface to be cleaned to improve the obstacle crossing ability, and approach the surface to be cleaned to optimize the dust collection effect.

[0071] The application further provides another possible implementation of the cleaning device. The cleaning device comprises a main body, a moving assembly arranged on the main body and supporting and driving the main body to move on a surface to be cleaned, a dust collection assembly arranged on the main body and performing cleaning work on the surface to be cleaned, and a driving structure. The dust collection assembly comprises a shell formed with a cavity, a cleaning roller arranged in the cavity, and a sealing member arranged on at least one side of the cleaning roller. The driving structure is arranged on at least one of the main body and the shell, and is configured to selectively drive the dust collection assembly to move between a lifting position and a working position and drive the sealing member to move between a sealing position and an opening position. The driving structure comprises a driving source, and a switching mechanism connected with the driving source and selectively connecting a first transmission path and a second transmission path. In the first transmission path connection state, the driving source provides power to drive the sealing member to move between the sealing position and the opening position. In the second transmission path connection state, the driving source provides power to drive the dust collection assembly to move between the lifting position and the working position.

[0072] In an embodiment, the switching mechanism comprises a driving wheel arranged on an output shaft of the driving source and a driven wheel engaged with the driving wheel. The driving wheel is configured to drive the driven wheel to move between a first engagement position and a second engagement position to connect the first transmission path or the second transmission path.

[0073] The dust collection assembly comprises a first transmission mechanism and a second transmission mechanism. The switching mechanism is configured to selectively connect the first transmission mechanism to connect the first transmission path and connect the second transmission mechanism to connect the second transmission path. The first transmission mechanism and the second transmission mechanism are arranged opposite to each other on two sides of the driven wheel.

[0074] The first transmission mechanism comprises a transmission gear engaged with the driven wheel and a gear portion engaged with the transmission gear and arranged on the sealing member. The second transmission mechanism comprises a traction frame arranged on the main body, a traction rope sliding through the traction frame, and a pulley rotatably arranged on the shell and engaged with the transmission gear. One end of the traction rope is connected to the pulley, and the other end is connected to the shell. When the pulley and the transmission gear are engaged, the traction rope is configured to be tightened or loosened under the rotation of the pulley to drive the shell to move.

[0075] Please refer to Figure 2 The cleaning device 3 of the present embodiment and the cleaning device 3 in the above embodiment are basically the same, and the difference lies in the switching mechanism 14, the first transmission mechanism and the second transmission mechanism.

[0076] Specifically, the driving wheel 23 provided on the output shaft 24 of the driving source 13 is a bevel gear, and the power output by the driving source 13 is selectively connected to the transmission path between the sealing member 20 or the dust collection assembly 1 via the driving wheel 23 by configuring the meshing time of the bevel gear and the driven wheel 22. Further, the driven wheel 22 moves between the first engagement position and the second engagement position in the process of meshing transmission with the driving wheel 23 to connect the first transmission path or the second transmission path. The dust collection assembly 1 includes a first transmission mechanism and a second transmission mechanism, and the switching mechanism 14 is configured to selectively connect the first transmission mechanism to connect the first transmission path and connect the second transmission mechanism to connect the second transmission path. Specifically, the first transmission mechanism and the second transmission mechanism are oppositely arranged on both sides of the driven wheel 22, and when the driven wheel 22 moves axially to the first engagement position, it cooperates with the first transmission mechanism, and when the driven wheel 22 moves axially to the second engagement position, it cooperates with the second transmission mechanism.

[0077] The first transmission mechanism includes a transmission gear 21 meshing with the driven wheel 22, and a gear portion 201 meshing with the transmission gear 21 and provided on the sealing member 20. The cooperation between the transmission gear 21 and the gear portion 201 is exactly the same as the cooperation between the adjusting gear 16 and the gear portion 201, and the rotation of the transmission gear 21 realizes the up-down movement of the sealing member 20 through the gear portion 201.

[0078] The second transmission mechanism includes a traction frame (not shown) provided on the main body, a traction rope 122 sliding through the traction frame, a pulley 121 rotatably provided on the housing 10 and meshing with the driven wheel 22, one end of the traction rope 122 being connected to the pulley 121 and the other end being connected to the housing 20, and when the pulley 121 and the driven wheel 22 mesh, the traction rope 122 is configured to be tightened or loosened under the rotation of the pulley to traction the housing 10 to move. The rotation of the pulley 121 is driven by the meshing of the driven wheel 22 and the pulley 121, thereby realizing the tightening or loosening of the traction rope 122.

[0079] In this embodiment, the driven wheel 22, the transmission gear 21 and the pulley 121 are all provided on the transmission shaft 19, and the transmission shaft 19 is rotatably provided on the housing 10. The driven wheel 22 is provided with engagement teeth on both sides of the axial direction, and the pulley 121 and the transmission gear 21 are also provided with engagement teeth on the side facing the driven wheel 22. By the cooperation of the engagement teeth, the engagement state or disengagement state can be formed between the transmission gear 21 or the pulley 121 distributed on both sides of the driven wheel 22 on the transmission shaft 19.

[0080] For example, in one operating state of the vacuum assembly 1, the driven wheel 22 moves towards the direction of the transmission gear 21 under the drive wheel 23 until the driven wheel 22 meshes with the transmission gear 21, that is, the switching mechanism 14 is in the first engaged position. In another operating state of the vacuum assembly 1, the driven wheel 22 moves towards the direction of the pulley 121 under the drive wheel 23, and the driven wheel 22 gradually disengages from the transmission gear 21. After disengaging from the transmission gear 21, the driven wheel 22 continues to move axially until it meshes with the pulley 121, that is, the switching mechanism 14 is in the second engaged position. In another operating state of the vacuum assembly 1, the driven wheel 22 moves towards the direction of the transmission gear 21 under the drive wheel 23, and the driven wheel 22 gradually disengages from the pulley 121. Thus, Figure 2 The central suction assembly 1 can selectively connect the transmission path with the seal 20 or the suction assembly 1 at different times under the drive of the drive wheel 23.

[0081] like Figure 2 As shown, a drive wheel 23 is provided on the output shaft 24 of the drive source 13. The drive wheel 23 can mesh with the driven wheel 22 on the transmission shaft 19. The helical gear meshing structure between the drive wheel 23 and the driven wheel 22 converts the power of the drive source 13 into the rotation of the transmission shaft 19. In another embodiment, the drive wheel and the driven wheel can be configured in other ways. For example, the driven wheel's displacement on the transmission shaft is in the same direction. When the driven wheel's displacement on the transmission shaft is a first length, the driven wheel meshes with the transmission gear. When the driven wheel's displacement on the transmission shaft is a second length, the driven wheel meshes with the pulley. Figure 2 The specific implementation structure does not constitute a specific limitation on the clutch mechanism; those skilled in the art can adjust its specific implementation as needed. For example, Figure 2 The driven wheel in the middle has opposite axial displacement. Those skilled in the art can adjust its displacement in the same direction as needed to connect the first transmission path or the second transmission path at different displacement lengths.

[0082] It should be noted that the height of the vacuuming assembly 1 above the ground is adjusted by the traction rope 122. This part can be referred to in the aforementioned embodiment and will not be repeated here. The traction rope 122 and the pulley 121 serve as a second transmission mechanism, and... Figure 1 Unlike other pulleys, pulley 121 is also configured with meshing teeth. When the meshing teeth mesh with driven wheel 22, the gear transmission between drive wheel 23 and driven wheel 22 can be transmitted to pulley 121, enabling the extension or retraction of the traction rope 122. The extension or retraction of the traction rope 122 is used to raise or lower the housing 10. This part can be implemented using… Figure 1 The same configuration as the second transmission mechanism 12 in the example.Figure 2 In the specific embodiment, the transmission shaft 19 is further provided with a transmission gear 21, and the transmission gear 21 drives the sealing member 20 to approach or move away from the surface to be cleaned when the transmission gear 21 rotates. Specifically, Figure 2 The difference between the dust suction assembly 1 and the example of the foregoing figure 1 is that the implementation structure of the dust suction assembly 1 for selectively connecting the first transmission path or the second transmission path through the switching mechanism is different. In this example, the transmission shaft 19 is in a sliding connection relationship with the driven wheel 22, the driven wheel 22 and the transmission shaft 19 rotate synchronously, and the driven wheel 22 can move axially on the transmission shaft 19. The transmission gear 21 is axially limitedly connected to the transmission shaft 19, and the rotation of the transmission shaft 19 does not drive the rotation of the transmission gear 21. The pulley 121 is fixedly connected to the transmission shaft 19 to realize synchronous rotation. The driving wheel 23 is fixedly connected to the output shaft of the driving source 13. The driving wheel 23 and the driven wheel 22 are configured to be in a bevel gear meshing transmission. When the motor output shaft 24 of the driving source 13 rotates forward or reversely, the driving wheel 23 and the driven wheel 22 are meshed, and the meshing of the two drives the driving wheel 23 to rotate the driven wheel 22, and on the other hand, the driving wheel 23 and the driven wheel 22 rotate in the transmission shaft 19 due to the setting of the bevel gear matching surface, which can drive the driven wheel 22 to slide on the transmission shaft 19. In other embodiments, the transmission gear and the pulley can be axially limitedly connected to the transmission shaft. At this time, the traction rope will not be provided with a margin, and when the dust suction assembly needs to be lifted, the driven wheel and the pulley are meshed, and when the dust suction assembly needs to be lowered, the driven wheel and the pulley are separated. Similarly, when the sealing member needs to move upward, the driven wheel and the transmission gear are meshed, and when the sealing member needs to move downward, the driven wheel and the transmission gear are separated.

[0083] In the application scenario of the cleaning device 3, the actuating unit (described as the switching mechanism 14 in the foregoing) is configured to selectively connect the transmission path of the sealing member 20 or the dust suction assembly. The foregoing Figure 2 The switching of the transmission path in the dust suction assembly shown in the figure can include the following working states:

[0084] Working state 1: the free end of the sealing member 20 approaches the surface to be cleaned, and the dust suction assembly 1 approaches the surface to be cleaned to perform the dust suction task, and the traction rope 122 is in a maximum margin state;

[0085] Working state 2: the motor is triggered to rotate in the first direction, the driving wheel 23 and the driven wheel 22 are in bevel gear meshing transmission, the driven wheel 22 rotates while moving in the direction of the pulley 121, the driven wheel 22 drives the transmission shaft 19 and the pulley 121 to rotate synchronously, at this time, the margin of the traction rope 122 gradually decreases until the driven wheel 22 and the pulley 121 are engaged, the pulley 121 rotates to tighten the traction rope 122, and the tightening of the traction rope 122 drives the dust suction assembly 1 to perform the lifting movement, and the dust suction assembly 1 is driven to the expected position / setting state of the lifting. In this process, the free end of the sealing member 20 remains in the state of approaching the surface to be cleaned.

[0086] Working state 3: the trigger motor rotates in the second direction opposite to the first direction, the driving wheel 23 on the output shaft 24 of the driving source 13 is in meshing transmission with the driven wheel 22, the driven wheel 22 rotates and moves towards the transmission gear 21 at the same time, so that the pulley 121 is disengaged from the driven wheel 22, and the dust collection assembly 1 generates a lowering movement under the action of its own gravity or the slack of the traction rope 122; during the process, the free end of the sealing piece 20 keeps close to the surface to be cleaned;

[0087] Working state 4: when the dust collection assembly 1 is lowered to the expected position / setting state, the transmission shaft 19 continues to rotate under the driving of the driving source 13 (during which the slack of the traction rope 122 is gradually generated); until the slack of the traction rope 122 is in the maximum slack state, during which the other end of the driven wheel 22 is engaged with the transmission gear 21, and the free end of the sealing piece 20 is away from the surface to be cleaned under the driving of the transmission gear 21, and stops at the expected position / setting state;

[0088] Working state 5: when the free end of the sealing piece 20 is away from the surface to be cleaned (the traction rope 122 is in the maximum slack state), the trigger motor rotates in the first direction (forward rotation), the driven wheel 22 rotates and moves towards the pulley 121 at the same time, the driven wheel 22 engaged with the transmission gear 21 is disengaged from the engagement state, and the sealing piece 20 generates a lowering movement under the action of its own gravity or the reverse thrust.

[0089] In the embodiment, the first and the second in the first direction and the second direction only represent the sequence of rotation. Figure 1 The first direction of the power output shaft (the output shaft of the motor) of the driving source 13 in the example of the dust collection assembly can be the same as or opposite to Figure 2 The first direction of the output shaft of the driving source 13 in the example of the dust collection assembly can be the same as or opposite to

[0090] On the basis of the foregoing cleaning device, the application further provides a control unit of a cleaning device, which selectively connects the transmission path of the sealing piece to make it away from or close to the ground during at least part of the period when the dust collection assembly performs cleaning, and selectively connects the transmission path of the floating movement of the dust collection assembly to make it close to or away from the ground during the remaining period.

[0091] The cleaning device of the application can selectively connect the transmission path of the sealing piece or the dust collection assembly in a time-sharing manner, and can realize the adjustment of the state of the dust collection assembly to the ground without increasing the motor, so as to meet the adjustment demand of the dust collection capacity in different cleaning states, can adapt to more cleaning scenes, and obtain better cleaning effect.

[0092] In the application, for the convenience of understanding, as Figure 1As shown, the top of the drawing sheet is defined as the top, the bottom of the drawing sheet is defined as the bottom. The drawing sheet outwardly is defined as the front side, the drawing sheet inwardly is defined as the back side. The above definitions are only for illustration and cannot be understood as a limitation to the present disclosure.

[0093] The above embodiments only express several implementation manners of the present disclosure, and the description is relatively specific and detailed, but cannot be understood as a limitation to the patent scope of the present disclosure. It should be noted that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
