DETAILED DESCRIPTION

[0047] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below.

[0048] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below. Figures 1-8 The wiper strip control structure and the cleaning equipment according to the embodiments of the present application are described below with reference to the accompanying drawings.

[0049] The present application provides a wiper strip control structure, as shown in Figures 1-4 The wiper strip control structure according to the embodiments of the present application comprises: a wiper strip 10, a lifting mechanism, and a mode switching mechanism 30.

[0050] The lifting mechanism is in transmission connection with the wiper strip 10, the mode switching mechanism 30 is connected with the wiper strip 10, and the mode switching mechanism 30 is configured to make the wiper strip 10 have a fixed state and a lifting state. In the fixed state, the wiper strip 10 keeps away from the surface to be cleaned, and in the lifting state, the wiper strip 10 contacts or keeps away from the surface to be cleaned under the driving of the lifting mechanism.

[0051] Specifically, the wiper strip control structure is arranged inside the shell of the cleaning equipment, the lifting mechanism can drive the wiper strip 10 to move in the direction intersecting the surface to be cleaned, and the mode switching mechanism 30 switches the wiper strip 10 between the fixed state and the lifting state. In the fixed state, the wiper strip 10 stably keeps away from the surface to be cleaned and is not movable, which is convenient for the maintenance and inspection of the cleaning equipment or for avoiding obstacles on the surface to be cleaned, and is convenient for the movement of the cleaning equipment. In the lifting state, the wiper strip 10 can be flexibly lifted to meet the cleaning requirements in complex scenes.

[0052] In one example, the lifting mechanism can be two swing wheels 21, which are arranged at intervals in the length direction of the wiper strip 10 and drive the wiper strip 10 to rise or fall. The shell can be provided with a notch at a position corresponding to the swing wheel 21, so that the swing wheel 21 has sufficient swing space in the front-back direction.

[0053] Thus, the wiper strip 10 can be switched between the fixed state and the lifting state by the mode switching mechanism 30, and the wiper strip 10 can be fixed away from the surface to be cleaned or can be lifted flexibly, so that the working state of the wiper strip 10 can be conveniently switched according to actual needs, and the flexibility and adaptability of the cleaning device are improved.

[0054] Referring to Figures 2-4 As shown, the mode switching mechanism 30 includes a first transmission member 32, the first transmission member 32 is connected with the wiper strip 10, and the first transmission member 32 has a fixed state and a lifting state in the direction intersecting the surface to be cleaned. In the lifting state, the first transmission member 32 is close to the surface to be cleaned, and in the fixed state, the first transmission member 32 is away from the surface to be cleaned. In this way, in the lifting state, the first transmission member 32 drives the wiper strip 10 to lift flexibly, which meets the cleaning requirements in complex scenes, and in the fixed state, the first transmission member 32 drives the wiper strip 10 to be away from the surface to be cleaned stably and cannot be moved, which is convenient for cleaning equipment maintenance, inspection or avoiding obstacles on the surface to be cleaned, and is convenient for the cleaning equipment to move.

[0055] In addition, the mode switching mechanism 30 further includes a second transmission member 31, the second transmission member 31 selectively moves in the length direction of the wiper strip 10 to drive the first transmission member 32 to adjust between the fixed state and the lifting state. Specifically, the second transmission member 31 is arranged on the side of the housing facing the surface to be cleaned and above the first transmission member 32. The second transmission member 31 can move leftward or rightward in the length direction, and the position of the first transmission member 32 in the length direction is unchanged. The first transmission member 32 can be adjusted between the fixed state and the lifting state by selectively moving the second transmission member 31 in the length direction of the wiper strip 10.

[0056] Further, the first transmission member 32 is provided with a first locking portion, and the second transmission member 31 is provided with a second locking portion. When the second transmission member 31 is located on one side of the length direction, the first locking portion and the second locking portion are misaligned, and the wiper strip 10 is in the fixed state. When the second transmission member 31 is located on the other side of the length direction, the first locking portion and the second locking portion are locked and matched, and the wiper strip 10 is in the lifting state.

[0057] In this embodiment, when the second transmission member 31 is located on the right side of the length direction, the first locking portion and the second locking portion are misaligned, and the wiper strip 10 is away from the surface to be cleaned and in the fixed state. When the second transmission member 31 is located on the left side of the length direction, the first locking portion and the second locking portion are locked and matched, and the wiper strip 10 is in the lifting state and can lift flexibly. By arranging the first locking portion and the second locking portion on the second transmission member 31 and the first transmission member 32, the wiper strip 10 can be switched between the fixed state and the lifting state.

[0058] Referring to Figures 2-4As shown, the second transmission member 31 is provided with a first protrusion 311 on the side facing the first transmission member 32, and the first protrusion 311 is formed with a first locking portion. The first transmission member 32 is provided with a second protrusion 321 on the side facing the second transmission member 31, and the second protrusion 321 is formed with a second locking portion. That is, the first locking portion can be the first protrusion 311 on the second transmission member 31, and the second locking portion can be the second protrusion 321 on the first transmission member 32. The first protrusion 311 and the second protrusion 321 are oppositely arranged.

[0059] The first transmission member 32 is provided with a clamping groove 322, and the clamping groove 322 is arranged at intervals with the second protrusion 321. When the wiper strip 10 is in the fixed state, the first protrusion 311 is located in the first clamping groove 322. When the first protrusion 311 cooperates with the first clamping groove 322, the first protrusion 311 and the first clamping groove 322 are locked, thereby driving the lifting mechanism to switch the wiper strip 10 to the fixed state.

[0060] When the wiper strip 10 is in the lifting state, the first protrusion 311 and the second protrusion 321 abut each other. The first locking portion and the second locking portion are locked and cooperated, and the wiper strip 10 can be lifted flexibly.

[0061] Referring to Figures 2-4 As shown, the second protrusion 321 is provided with an inclined surface 323 on the side facing the first protrusion 311. When the first protrusion 311 moves, it can slide along the inclined surface 323 of the second protrusion 321. This improves the accuracy and efficiency of the trajectory of the movement of the second transmission member 31 and improves the reliability of the mode switching mechanism 30.

[0062] Referring to Figures 2-4 As shown, the second protrusion 321 is provided with a groove 324 on the side facing the second transmission member 31. When the wiper strip 10 is in the lifting state, the first protrusion 311 is located in the groove 324. That is, when the first protrusion 311 abuts against the second protrusion 321, the first protrusion 311 is cooperated in the groove 324 of the second protrusion 321. That is, the first locking portion and the second locking portion are locked and cooperated, so that the wiper strip 10 can be lifted flexibly.

[0063] Further, the first protrusion 311 and the second protrusion 321 can be multiple. The multiple first protrusions 311 are arranged at intervals in the length direction of the second transmission member 31, and the multiple second protrusions 321 are arranged at intervals in the length direction of the first transmission member 32. The multiple first protrusions 311 and the multiple second protrusions 321 are cooperated one by one. In this way, the transmission stability between the second transmission member 31 and the first transmission member 32 can be improved.

[0064] Further, the second protrusion 321 is composed of two sub-protrusions, which are respectively arranged on both sides of the first transmission member 32. Similarly, the first protrusion 311 is also composed of two sub-protrusions, which are arranged at intervals in the width direction of the second transmission member 31. The two sub-protrusions of the first protrusion 311 correspond to the two sub-protrusions of the second protrusion 321 one by one.

[0065] Referring to Figures 1-2 As shown, the second transmission member 31 is provided with a toggle switch 312 at one end away from the first transmission member 32, which slides in the sliding groove on the shell. Specifically, the toggle switch 312 is operated by the user, and the user controls the toggle switch 312 to slide left and right in the sliding groove on the shell, thereby driving the second transmission member 31 to move left and right, realizing the function of changing the state of the scraping strip 10.

[0066] Referring to Figures 2-4 As shown, the scraping strip control structure further comprises a first elastic member 33, one end of which abuts against the first transmission member 32 and the other end of which abuts against the shell. Specifically, when the first locking portion and the second locking portion are locked together, the first protrusion 311 and the clamping groove 322 on the first transmission member 32 are separated, the first elastic member 33 is in a relaxed state, and the scraping strip 10 is in a lifting state and can be lifted flexibly. When the first locking portion and the second locking portion are staggered, the first protrusion 311 can slide along the inclined surface 323 of the second protrusion 321 and be locked with the clamping groove 322 on the first transmission member 32, the first elastic member 33 is compressed, and the scraping strip 10 is in a fixed state and cannot be lifted.

[0067] Preferably, the first elastic member 33 is a spring.

[0068] In summary, the process of the user operating the toggle switch 312 to switch the mode of the scraping strip 10 is as follows: moving the toggle switch 312 from the left side to the right side: the toggle switch 312 drives the second transmission member 31 to move synchronously to the right, the first protrusion 311 on the second transmission member 31 pushes the first transmission member 32 to move upward, and the first transmission member 32 drives the scraping strip 10 to move upward synchronously. When the toggle switch 312 moves to the rightmost side, the first protrusion 311 on the second transmission member 31 and the clamping groove 322 on the first transmission member 32 are locked, and the mode switching mechanism 30 is switched to the fixed state.

[0069] Moving the toggle switch 312 from the right side to the left side: the toggle switch 312 drives the second transmission member 31 to move synchronously to the left, and the first elastic member 33 assists the first protrusion 311 on the second transmission member 31 to gradually separate from the clamping groove 322 on the first transmission member 32, so that the scraping strip 10 can be freely lifted and lowered under the drive of the swing wheel 21. When the toggle switch 312 moves to the leftmost side, the mode switching mechanism 30 is switched to the lifting state.

[0070] This utility model proposes another scraper control structure, referring to... Figures 5-8 As shown, the mode switching mechanism 30 includes a base plate 34 and a connecting rod 36. The connecting rod 36 is mounted on the base plate 34, and both ends of the connecting rod 36 are connected to the first transmission member 32 to switch between a lifting state and a fixed state when the first transmission member 32 is subjected to force. Specifically, the inner side of the first transmission member 32 is provided with two through holes 352, which are spaced apart along the length of the first transmission member 32. After the connecting rod 36 passes through the base plate 34, both ends are connected to the through holes 352, so that the first transmission member 32 and the connecting rod 36 can move synchronously.

[0071] Thus, when an external force is applied to the first transmission member 32, the first transmission member 32 will adjust between a fixed state and a lifting state. For example, when a downward pressure is applied to the first transmission member 32, the first transmission member 32 will move from the lifting state to the fixed state, and under the limiting cooperation of the connecting rod 36, the first transmission member 32 will stop in the fixed state. As another example, when an upward pressure is applied to the first transmission member 32, the first transmission member 32 will move from the fixed state to the lifting state, and under the limiting cooperation of the connecting rod 36, the first transmission member 32 will stop in the lifting state, so that the scraper 10 moves away from or contacts the surface to be cleaned.

[0072] In addition, an operating lever 38 is provided on the first transmission member 32 so that force can be applied to the first transmission member 32 through the operating lever 38. The user can press the operating lever 38 to drive the first transmission member 32 to rise or fall, thereby causing the scraper 10 to rise or fall.

[0073] Of course, the first transmission component 32 may not have an operating lever 38, and the user can directly press the first transmission component 32.

[0074] Reference Figure 8 As shown, the connecting rod 36 includes a first rotating part 361, a connecting part 362, and a second rotating part 363. The first rotating part 361 and the second rotating part 363 are connected to each other and staggered. The first rotating part 361 passes through the base plate 34, and the second rotating part 363 cooperates with the first transmission member 32. The connecting part 362 connects between the first rotating part 361 and the second rotating part 363 and is perpendicular to the first rotating part 361 and the second rotating part 363. In this way, the first rotating part 361 is fixed in the floor and can rotate, and the second rotating part 363 and the connecting part 362 can rotate accordingly, so that the second rotating part 363 can change its position in the vertical direction.

[0075] Reference Figure 8As shown, the connecting rod 36 is at least two, and the at least two connecting rods 36 are arranged in the up-down direction. By arranging at least two connecting rods 36, better balance can be provided, and the swing or instability phenomenon that may occur in a single connecting rod 36 can be reduced. The double connecting rod 36 design disperses the load, increases the synchronization of the movement of the first transmission member 32 and the connecting rod 36, and improves the reliability of the mode switching mechanism 30.

[0076] Referring to Figure 7 As shown, the mode switching mechanism 30 further comprises a second elastic member 37, one end of the second elastic member 37 abuts against the bottom plate 34 and the other end abuts against the first transmission member 32. Specifically, the inner side of the first transmission member 32 is provided with a second matching part 351, and the bottom plate 34 is provided with a first matching part 341, one end of the second elastic member 37 is connected with the first matching part 341 of the bottom plate 34, and the other end is connected with the second matching part 351 of the first transmission member 32.

[0077] Among them, the second elastic member 37 can be a torsion spring. The first matching part 341 and the second matching part 351 can both be matching columns, the first matching part 341 is a matching column arranged on the bottom plate 34, and the second matching part 351 is a matching column arranged on the first transmission member 32.

[0078] In addition, the second elastic member 37 can be at least two, and the at least two second elastic members 37 are spaced in the length direction of the first transmission member 32, and for the same reason, the first matching part 341 and the second matching part 351 are at least two groups. In this way, by arranging at least two second elastic members 37, the first transmission member 32 is more stable when adjusting between the first position and the second position, and the damping force when adjusting is more appropriate.

[0079] In combination with Figures 6-8 As shown, the upper end of the bottom plate 34 is provided with a sealing flange, and the upper end of the first transmission member 32 and the side facing the bottom plate 34 is provided with a avoiding slot, and the avoiding slot and the sealing flange cooperate when the first transmission member 32 is in the first position. That is, a sealing flange is arranged on the bottom plate 34, and an avoiding slot that can cooperate with the sealing flange is arranged on the first transmission member 32, so that when the first transmission member 32 is in the first position, the avoiding slot and the sealing flange cooperate, thereby improving the integrity of the wiper control structure, and preventing dust from entering between the first transmission member 32 and the bottom plate 34 in the first position.

[0080] In summary, the process of the user operating the operating rod 38 to switch the mode of the wiper 10 is as follows: press the operating rod 38 downward, the connecting rod 36 drives the first transmission member 32 and the wiper 10 to move downward synchronously, the second elastic member 37 rotates downward, and its state switches from being opened to being folded, and then from being folded to being opened, until the connecting rod 36 moves to the bottom, and the wiper 10 switches to the lifting state.

[0081] Pulling up the operating lever 38, the connecting rod 36 drives the first transmission member 32 and the scraping strip 10 to move upward synchronously, and the second elastic member 37 rotates upward, and its state is switched from opening to folding and then from folding to opening until the connecting rod 36 moves to the upper part and the scraping strip 10 is switched to the fixed state.

[0082] The scraping strip control structure can further include a driving unit, the driving unit and the first transmission member 32 are in transmission connection, and the driving unit is used for adjusting the first transmission member 32 between the fixed state and the lifting state.

[0083] The scraping strip control structure further includes a controller, the controller and the driving unit are in electrical connection, and the controller is configured to selectively control the driving unit to start. The controller is connected with the driving unit and is used for controlling the working state of the driving unit according to an instruction or a signal, so as to realize the switching of the scraping strip 10 between the lifting state and the fixed state.

[0084] The scraping strip control structure can be designed to have two modes of manual and automatic. In the manual mode, the user directly controls the state of the scraping strip 10 through a button or a touch screen and the like input device. In the automatic mode, the controller automatically adjusts the state of the scraping strip 10 according to a preset cleaning program (such as detecting a self-cleaning mode) or a sensor signal (such as detecting a carpet). In this way, the working state of the scraping strip 10 can be conveniently switched according to actual needs, and the flexibility and adaptability of the cleaning equipment are improved.

[0085] The utility model further provides a kind of scraping strip control structure, including: scraping strip 10, lifting mechanism and mode switching mechanism 30.

[0086] The lifting mechanism and the scraping strip 10 are in transmission connection, the mode switching mechanism 30 is connected with the scraping strip 10, and the mode switching mechanism 30 is configured to make the scraping strip 10 have a second position and a first position, wherein, in the second position, the scraping strip 10 keeps away from the surface to be cleaned, and in the first position, the scraping strip 10 contacts or keeps away from the surface to be cleaned under the driving of the lifting mechanism.

[0087] Specifically, the scraping strip control structure is arranged inside the shell of the cleaning equipment, the lifting mechanism can drive the scraping strip 10 to move in the direction intersecting the surface to be cleaned, and the mode switching mechanism 30 switches the scraping strip 10 between the second position and the first position. In the second position, the scraping strip 10 stably keeps away from the surface to be cleaned and is not movable, which is convenient for cleaning equipment maintenance, inspection or avoiding obstacles on the surface to be cleaned, and facilitates the movement of the cleaning equipment. In the first position, the scraping strip 10 can be lifted flexibly, which meets the cleaning requirements of complex scenes.

[0088] In one example, the lifting mechanism can be two swing wheels 21 arranged at intervals in the length direction of the blade 10 to drive the blade 10 to rise or fall. The shell can be provided with a notch at a position corresponding to the swing wheel 21 to provide sufficient swing space for the swing wheel 21 in the front-back direction.

[0089] Thus, the blade 10 can be switched between the second position and the first position by the mode switching mechanism 30, and the blade 10 can be fixed away from the surface to be cleaned or can be flexibly lifted, so that the working state of the blade 10 can be conveniently switched according to actual needs, and the flexibility and adaptability of the cleaning device are improved.

[0090] Referring to Figures 2-4 As shown, the mode switching mechanism 30 includes a first transmission member 32 connected with the blade 10, and the first transmission member 32 has a second position and a first position in the direction intersecting the surface to be cleaned. In the first position, the first transmission member 32 is close to the surface to be cleaned, and in the second position, the first transmission member 32 is away from the surface to be cleaned. In this way, in the first position, the first transmission member 32 drives the blade 10 to be flexibly lifted to meet the cleaning requirements of complex scenes, and in the second position, the first transmission member 32 drives the blade 10 to be stably away from the surface to be cleaned and immovable, so as to facilitate the maintenance, inspection or avoidance of obstacles of the cleaning device on the surface to be cleaned, and facilitate the movement of the cleaning device.

[0091] The mode switching mechanism 30 further includes a second transmission member 31 selectively moved in the length direction of the blade 10 to drive the first transmission member 32 to adjust between the second position and the first position. Specifically, the second transmission member 31 is arranged on the side of the shell facing the surface to be cleaned and above the first transmission member 32. The second transmission member 31 can be moved leftward or rightward in the length direction, and the position of the first transmission member 32 in the length direction remains unchanged. By selectively moving the second transmission member 31 in the length direction of the blade 10, the first transmission member 32 can be adjusted between the second position and the first position.

[0092] Further, the first transmission member 32 is provided with a first locking portion, and the second transmission member 31 is provided with a second locking portion. When the second transmission member 31 is located on one side of the length direction, the first locking portion and the second locking portion are misaligned, and the blade 10 is in the second position. When the second transmission member 31 is located on the other side of the length direction, the first locking portion and the second locking portion are locked and matched, and the blade 10 is in the first position.

[0093] In the embodiment, when the second transmission member 31 is located at the right side in the length direction, the first locking portion and the second locking portion are misaligned, and at this time, the wiper strip 10 is away from the surface to be cleaned and is in the second position. When the second transmission member 31 is located at the left side in the length direction, the first locking portion and the second locking portion are locked and matched, and at this time, the wiper strip 10 is in the first position and can be flexibly lifted and lowered. By providing the first locking portion and the second locking portion on the second transmission member 31 and the first transmission member 32, the wiper strip 10 can be switched between the second position and the first position.

[0095] The first transmission member 32 is provided with a clamping groove 322, and the clamping groove 322 and the second protrusion 321 are arranged at intervals. When the wiper strip 10 is in the second position, the first protrusion 311 is located in the first clamping groove 322. When the first protrusion 311 cooperates with the first clamping groove 322, they are locked with each other, thereby driving the lifting mechanism to switch the wiper strip 10 to the second position.

[0096] When the wiper strip 10 is in the first position, the first protrusion 311 and the second protrusion 321 abut against each other. In this way, the first locking portion and the second locking portion are locked and matched, and the wiper strip 10 is in the first position and can be flexibly lifted and lowered.

[0097] Referring to Figures 2-4 As shown in the figure, the side of the second protrusion 321 facing the first protrusion 311 is provided with an inclined surface 323. When the first protrusion 311 moves, it can slide along the inclined surface 323 of the second protrusion 321, thereby improving the accuracy and efficiency of the trajectory of the movement of the second transmission member 31 and improving the reliability of the mode switching mechanism 30.

[0098] Referring to Figures 2-4 As shown in the figure, the side of the second protrusion 321 facing the second transmission member 31 is provided with a groove 324. When the wiper strip 10 is in the first position, the first protrusion 311 is located in the groove 324. That is, when the first protrusion 311 abuts against the second protrusion 321, the first protrusion 311 cooperates in the groove 324 of the second protrusion 321, that is, the first locking portion and the second locking portion are locked and matched, so that the wiper strip 10 is in the first position and can be flexibly lifted and lowered.

[0099] Further, the first protrusion 311 and the second protrusion 321 can each be a plurality, the plurality of first protrusions 311 are arranged at intervals in the length direction of the second transmission member 31, and the plurality of second protrusions 321 are arranged at intervals in the length direction of the first transmission member 32, and the plurality of first protrusions 311 and the plurality of second protrusions 321 are one-to-one corresponding matching. By being arranged in this way, the transmission stability between the second transmission member 31 and the first transmission member 32 can be improved.

[0100] Further, the second protrusion 321 is composed of two sub-protrusions, and the two sub-protrusions are arranged on both sides of the first transmission member 32. Similarly, the first protrusion 311 is also composed of two sub-protrusions, and the two sub-protrusions are arranged at intervals in the width direction of the second transmission member 31. The two sub-protrusions of the first protrusion 311 are one-to-one corresponding matching with the two sub-protrusions of the second protrusion 321.

[0101] Referring to Figures 1-2 As shown in the figure, the end of the second transmission member 31 away from the first transmission member 32 is provided with a toggle switch 312, and the toggle switch 312 slides in the sliding groove on the shell. Specifically, the toggle switch 312 is operated by the user, and the user controls the toggle switch 312 to slide left and right in the sliding groove on the shell, thereby driving the second transmission member 31 to move left and right, realizing the function of changing the state of the wiper strip 10.

[0102] Referring to Figures 2-4 As shown in the figure, the wiper strip control structure further includes a first elastic member 33, one end of the first elastic member 33 abuts against the first transmission member 32 and the other end abuts against the shell. Specifically, when the first locking portion and the second locking portion are locked and matched, the first protrusion 311 and the clamping groove 322 on the first transmission member 32 are separated, the first elastic member 33 is in a relaxed state, and the wiper strip 10 is in the first position and can be flexibly lifted. When the first locking portion and the second locking portion are staggered, the first protrusion 311 can slide along the inclined surface 323 of the second protrusion 321 and be locked with the clamping groove 322 on the first transmission member 32, the first elastic member 33 is compressed, and the wiper strip 10 is in the second position and cannot be lifted.

[0103] Among them, the first elastic member 33 can be a spring.

[0104] In summary, the process of the user operating the toggle switch 312 to switch the mode of the wiper strip 10 is as follows: the toggle switch 312 is toggled from the left side to the right side: the toggle switch 312 drives the second transmission member 31 to move synchronously to the right, the first protrusion 311 on the second transmission member 31 pushes the first transmission member 32 to move upward, the first transmission member 32 drives the wiper strip 10 to move synchronously upward, and when the toggle switch 312 moves to the rightmost side, the first protrusion 311 on the second transmission member 31 and the clamping groove 322 on the first transmission member 32 are locked, and the mode switching mechanism 30 is switched to the second position.

[0105] When the toggle switch 312 is toggled from the right side to the left side: the toggle switch 312 drives the second transmission member 31 to move to the left side synchronously, the first elastic member 33 assists the first protrusion 311 on the second transmission member 31 to gradually separate from the clamping slot 322 on the first transmission member 32, and the wiper strip 10 can be freely raised and lowered under the drive of the swing wheel 21. When the toggle switch 312 is moved to the leftmost side, the mode switching mechanism 30 is switched to the first position.
