[0105] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0106] like Figures 1 to 14 As shown, the present disclosure first provides a scraper bar assembly 1. The scraper bar assembly 1 can be configured to be installed on a cleaning host 2. The cleaning host 2 can include but is not limited to: a floor scrubber host, a floor sweeper host, a floor sweeping robot host, etc.

[0107] The scraper bar assembly 1 provided in the present disclosure may include: a scraper bar 11. The scraper bar 11 may be configured to switch between a first state and a second state according to the motion state of the cleaning host 2 and the distance between the cleaning host 2 and an obstacle. In the first state, a first distance L1 may be present between the bottom of the scraper bar 11 and the surface to be cleaned 3; in the second state, a second distance L2 may be present between the bottom of the scraper bar 11 and the surface to be cleaned 3. The first distance L1 may be greater than the second distance L2. That is, it can be understood that when the scraper bar 11 switches to the first state, the scraper bar 11 is raised; when the scraper bar 11 switches to the second state, the scraper bar 11 is lowered.

[0108] With such a configuration, the present invention can accurately judge whether it is currently necessary to clean the area near the obstacle based on the movement direction of the cleaning host 2 and the distance between the cleaning host 2 and the obstacle. After judging that it is currently necessary to clean the area near the obstacle, the scraper 11 is accurately switched to the second state, so that the distance between the scraper 11 and the surface to be cleaned 3 is closer, thereby being able to remove dirt, water stains, etc. near the obstacle.

[0109] Moreover, after determining that there is currently no need to clean the area near the obstacle, the scraper 11 can be maintained in the first state, or the scraper 11 can be switched from the second state to the first state, so that the scraper 11 is farther away from the surface 3 to be cleaned, thereby avoiding the scraper 11 being accidentally put down when the cleaning host 2 is not close to the obstacle and affecting the normal operation of the cleaning host 2.

[0110] And / or, the wiper strip assembly 1 may include: a wiper strip 11 and a trigger member 16 , and the wiper strip 11 may be configured to switch between a first state and a second state when the trigger member 16 is triggered.

[0111] With this arrangement, the state of the scraper bar 11 can be switched as needed, that is, when it is necessary to clean dirt, water stains, etc. on the cleaning surface 3, the trigger member 16 can be triggered to switch the scraper bar 11 to the second state, so that cleaning can be performed using the scraper bar 11. When it is not necessary to clean dirt, water stains, etc. on the cleaning surface 3, the trigger member 16 can be triggered to switch the scraper bar 11 to the first state, so as to facilitate cleaning operations such as cleaning the main body 2.

[0112] It should be noted that the above technical solution includes a total of three embodiments, namely: the first embodiment: the scraper bar 11 is configured to switch between the first state and the second state according to the movement direction of the cleaning host 2 and the distance between the cleaning host 2 and the obstacle. The second embodiment: the scraper bar assembly 1 includes: a scraper bar 11 and a trigger 16, and the scraper bar 11 is configured to switch between the first state and the second state when the trigger 16 is triggered. The third embodiment: the scraper bar assembly 1 includes: a scraper bar 11 and a trigger 16, and the scraper bar 11 is configured to switch between the first state and the second state according to the movement direction of the cleaning host 2 and the distance between the cleaning host 2 and the obstacle, and the scraper bar 11 is configured to switch between the first state and the second state when the trigger 16 is triggered.

[0113] Furthermore, the technical effects of the first embodiment and the second embodiment may refer to the corresponding descriptions above, and the technical effects of the third embodiment may be the superposition of the technical effects of the first embodiment and the technical effects of the second embodiment.

[0114] In one embodiment, the second distance L2 may be 0. With this configuration, when the scraper bar 11 is switched to the second state, the bottom of the scraper bar 11 can be in contact with the surface to be cleaned 3, thereby preventing some dirt or water stains from leaking from the gap between the bottom of the scraper bar 11 and the surface to be cleaned 3, thereby improving the cleaning effect of the scraper bar 11.

[0115] In one embodiment of the present disclosure, the scraper bar 11 may be installed at the front end of the cleaning main body 2. The scraper bar 11 may be configured so that when the cleaning main body 2 moves along the first direction X, the scraper bar 11 may be switched to the first state.

[0116] In this way, when the cleaning host 2 moves along the first direction X, the cleaning host 2 will clean the dirt without using the scraper 11 to clean the dirt. Therefore, switching the scraper 11 to the first state at this time can avoid the scraper 11 hindering the cleaning work of the cleaning host 2, and can also avoid the scraper 11 hindering the movement of the cleaning host 2, thereby ensuring the smoothness of the movement of the cleaning host 2.

[0117] The scraper bar 11 can be configured to switch to the second state when the distance between the front end of the cleaning main body 2 and the obstacle is less than or equal to a preset distance and the cleaning main body 2 moves in a direction opposite to the first direction X. The first direction X is the direction from the rear end of the cleaning main body 2 to the front end of the cleaning main body 2.

[0118] When the distance between the front end of the cleaning body 2 and the obstacle is less than or equal to a preset distance, the cleaning body 2 can be determined to be near the obstacle. Furthermore, if the cleaning body 2 moves in a direction opposite to the first direction X, it can be considered that the cleaning body 2 has completed cleaning near the obstacle. However, there may be blind spots near the obstacle that the cleaning body 2 cannot clean, making it unable to clean these blind spots. In this case, the scraper bar 11 can be switched to the second state, allowing it to clean dirt, water stains, etc. in these blind spots, thereby improving the cleaning effect.

[0119] The scraping bar 11 can be configured to switch to the second state when the cleaning host 2 stops moving. In this way, the scraping bar 11 can be put down when the cleaning host 2 stops moving, avoiding the scraping bar 11 from being in the raised state all the time, thereby improving the service life of the scraping bar 11.

[0120] The scraper bar 11 can be configured to switch to the second state when the distance between the front end of the cleaning main body 2 and the obstacle is less than or equal to a preset distance, and the cleaning main body 2 moves in a direction opposite to the first direction X. The scraper bar 11 can also be configured to switch to the second state when the cleaning main body 2 stops moving. This configuration not only allows the scraper bar 11 to clean dirt, water stains, etc. in blind spots to improve the cleaning effect, but also prevents the scraper bar 11 from being constantly raised, thereby increasing the service life of the scraper bar 11.

[0121] In one embodiment, the cleaning host 2 may include a cleaning working part 21. The cleaning working part 21 may be a roller brush, a side brush, etc. The scraper bar 11 may be configured to be installed at the front end of the cleaning working part 21.

[0122] In this embodiment, the scraper bar 11 is arranged at the front end of the cleaning working part 21, so that the distance between the scraper bar 11 and the cleaning working part 21 is closer, so that the dirt or water stains scraped by the scraper bar 11 can be gathered near the cleaning working part 21, so that the cleaning working part 21 can remove the dirt or water stains scraped by the scraper bar 11.

[0123] When the cleaning working part 21 moves in the first direction X, the scraper bar 11 switches to the first state. When the distance between the front end of the cleaning working part 21 and the obstacle is less than or equal to the preset distance and the cleaning working part 21 moves in the direction opposite to the first direction X, the scraper bar 11 switches to the second state.

[0124] With this arrangement, since the cleaning working portion 21 is responsible for cleaning dirt within the cleaning main body 2, when the distance between the front end of the cleaning working portion 21 and the obstacle is less than or equal to the preset distance, the blind spot of the cleaning main body 2 can be more accurately determined. Therefore, by using the distance between the front end of the cleaning working portion 21 and the obstacle for determination, the accuracy of the state switching of the scraper 11 can be improved, thereby further improving the cleaning effect.

[0125] When the cleaning work part 21 stops moving, the scraping strip 11 can be switched to the second state. Such arrangement allows the scraping strip 11 to be put down when the cleaning work part 21 stops moving, thereby preventing the scraping strip 11 from being in the raised state all the time and thereby improving the service life of the scraping strip 11.

[0126] The scraper 11 switches to the second state when the distance between the front end of the cleaning working portion 21 and the obstacle is less than or equal to a predetermined distance and the cleaning working portion 21 moves in a direction opposite to the first direction X. Furthermore, the scraper 11 can switch to the second state when the cleaning working portion 21 stops moving. This configuration not only improves the accuracy of the scraper 11's state switching, thereby further enhancing the cleaning effect, but also increases the service life of the scraper 11.

[0127] In one embodiment of the present disclosure, Figure 4 、 Figure 5 、 Figures 7 to 14 As shown, the scraper bar assembly 1 may include at least two scraper bars 11. The at least two scraper bars 11 may include a first scraper bar 113 and a second scraper bar 114. The first scraper bar 113 may be configured to be installed at the front end of the cleaning main body 2, and the second scraper bar 114 may be configured to be installed at the rear end of the cleaning main body 2.

[0128] When the cleaning host 2 moves along the first direction X or in a direction opposite to the first direction X, the first scraper 113 and the second scraper 114 are both switched to the first state. At this time, the first scraper 113 and the second scraper 114 can be prevented from hindering the cleaning work of the cleaning host 2, and the first scraper 113 and the second scraper 114 can be prevented from hindering the movement of the cleaning host 2, thereby ensuring the smoothness of the movement of the cleaning host 2.

[0129] When the distance between the front end of the cleaning main body 2 and the obstacle is less than or equal to the preset distance, and the cleaning main body 2 moves in a direction opposite to the first direction X, the first scraping bar 113 can be switched to the second state, and the second scraping bar 114 can be switched to the first state. In this way, the first scraping bar 113 can be used to clean the blind spots at the front end of the cleaning main body 2, and the second scraping bar 114 can be prevented from affecting the movement of the cleaning main body 2.

[0130] When the distance between the rear end of the cleaning main body 2 and the obstacle is less than or equal to the preset distance, and the cleaning main body 2 moves along the first direction X, the second scraping bar 114 can be switched to the second state, and the first scraping bar 113 can be switched to the first state. In this way, the second scraping bar 114 can be used to clean the blind spots at the rear end of the cleaning main body 2, and the first scraping bar 113 can be prevented from affecting the movement of the cleaning main body 2.

[0131] In this way, by providing the first scraping strip 113 and the second scraping strip 114 , this embodiment can clean the blind spots at the front and rear ends of the cleaning main body 2 , thereby further improving the cleaning effect.

[0132] When the cleaning main body 2 stops moving, the first scraping bar 113 and / or the second scraping bar 114 switches to the second state. In this configuration, the first scraping bar 113 and / or the second scraping bar 114 can be lowered when the cleaning main body 2 stops moving, thereby avoiding the first scraping bar 113 and / or the second scraping bar 114 being in the raised state all the time, thereby increasing the service life of the first scraping bar 113 and / or the second scraping bar 114.

[0133] In one embodiment, the first scraping bar 113 may be configured to be installed at the front end of the cleaning working portion 21 , and the second scraping bar 114 may be configured to be installed at the rear end of the cleaning working portion 21 .

[0134] When the cleaning working part 21 moves along the first direction X or in a direction opposite to the first direction X, the first scraper 113 and the second scraper 114 are both switched to the first state. At this time, the first scraper 113 and the second scraper 114 can be prevented from hindering the cleaning work of the cleaning working part 21, and the first scraper 113 and the second scraper 114 can be prevented from hindering the movement of the cleaning working part 21, thereby ensuring the smoothness of the movement of the cleaning working part 21.

[0135] When the distance between the front end of the cleaning working unit 21 and the obstacle is less than or equal to a preset distance, and the cleaning working unit 21 moves in a direction opposite to the first direction X, the first scraping bar 113 can be switched to the second state, and the second scraping bar 114 can be switched to the first state. This arrangement allows the first scraping bar 113 to clean blind spots at the front end of the cleaning working unit 21, while also preventing the second scraping bar 114 from affecting the movement of the cleaning working unit 21.

[0136] When the distance between the rear end of the cleaning working section 21 and the obstacle is less than or equal to a predetermined distance, and the cleaning working section 21 moves in the first direction X, the second scraping bar 114 can be switched to the second state, and the first scraping bar 113 can be switched to the first state. This arrangement allows the second scraping bar 114 to clean blind spots at the rear end of the cleaning working section 21, while also preventing the first scraping bar 113 from affecting the movement of the cleaning working section 21.

[0137] When the cleaning working part 21 stops moving, the first scraping bar 113 and / or the second scraping bar 114 switches to the second state. This configuration allows the first scraping bar 113 and / or the second scraping bar 114 to be lowered when the cleaning working part 21 stops moving, thereby preventing the first scraping bar 113 and / or the second scraping bar 114 from being constantly raised, thereby increasing the service life of the first scraping bar 113 and / or the second scraping bar 114.

[0138] In one embodiment of the present disclosure, the preset distance can be greater than or equal to 0 mm and less than or equal to 2 mm, for example, 0 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, etc. This arrangement allows the scraper 11 to be closer to the obstacle, improving the cleaning effect of the scraper 11. It also prevents the scraper 11 from being lowered too far from the obstacle, which could affect the normal operation of the cleaning unit 21. However, this is not limiting, and the preset distance can also be other distances that can be set based on actual needs, all of which are within the scope of protection of the present disclosure.

[0139] In one embodiment of the present disclosure, Figure 6 As shown, the scraper bar 11 can be configured to switch between a first state and a second state when the trigger 16 is actively triggered. For example, when the front end of the cleaning body 2 approaches an obstacle, the operator can actively trigger the trigger 16 to switch the scraper bar 11 from the first state to the second state to clean dirt, water stains, etc. near the obstacle. After the scraper bar 11 has finished cleaning the dirt, water stains, etc. near the obstacle, the operator can actively trigger the trigger 16 to switch the scraper bar from the second state to the first state. This configuration can improve the operator's operational autonomy, allowing the scraper bar 11 to switch states at will according to the operator's needs.

[0140] The scraper bar 11 can be configured to switch between a first state and a second state when the trigger member 16 is passively triggered. For example, when the front end of the cleaning main unit 2 approaches an obstacle, the trigger member 16 may collide with the obstacle. Here, the trigger member 16 is triggered by the obstacle, and the scraper bar 11 can automatically switch from the first state to the second state to clean dirt, water stains, etc. near the obstacle. After the scraper bar 11 has finished cleaning the dirt, water stains, etc. near the obstacle, the trigger member 16 and the obstacle move away from each other, and the scraper bar 11 can automatically switch from the second state to the first state. This configuration ensures that the scraper bar 11 is not lowered until the cleaning main unit 2 approaches an obstacle.

[0141] In one embodiment, the scraper bar 11 can be configured to switch between the first state and the second state when the trigger member 16 is actively triggered, and to switch between the first state and the second state when the trigger member 16 is passively triggered. This configuration can improve the operator's operational autonomy, allowing the state of the scraper bar 11 to be switched arbitrarily according to the operator's needs, and can ensure that the scraper bar 11 is not lowered until the cleaning main body 2 approaches an obstacle.

[0142] In one embodiment of the present disclosure, when the trigger member 16 is actively triggered, the first scraper strip 113 and / or the second scraper strip 114 can switch between the first state and the second state. This configuration can further enhance the operator's operational autonomy, allowing the operator to switch the state of the first scraper strip 113 and / or the second scraper strip 114 at will according to the operator's needs.

[0143] When the trigger 16 is passively triggered, the first scraping bar 113 and / or the second scraping bar 114 can be switched between the first state and the second state. Such arrangement ensures that the first scraping bar 113 and / or the second scraping bar 114 are just put down when the cleaning main unit 2 is near an obstacle.

[0144] In one embodiment, when the trigger member 16 is actively or passively triggered, the first scraper bar 113 and / or the second scraper bar 114 can switch between a first state and a second state. This configuration further enhances the operator's operational autonomy, allowing the first scraper bar 113 and / or the second scraper bar 114 to be switched as needed, and ensuring that the first scraper bar 113 and / or the second scraper bar 114 are not lowered until the cleaning main unit 2 approaches an obstacle. In one embodiment, the trigger member 16 can be a separately provided trigger block, etc., but is not limited thereto. The trigger member 16 can also be other trigger structures, which can be selected and configured according to actual circumstances.

[0145] like Figures 7 to 14As shown, the scraper strip assembly 1 may further include a driving device 12. The driving device 12 may be in contact with or connected to the scraper strip 11 to drive the scraper strip 11 to switch between the first state and the second state.

[0146] In one embodiment, the driving device 12 may include a driving member 121 and a state switching member 122. The driving member 121 may be a motor, etc. The state switching member 122 may be connected to the driving member 121 and configured to switch the scraper strip 11 between a first state and a second state.

[0147] The scraper strip assembly 1 may further include a support shell 13. The driving member 121 may be mounted on the support shell 13, thereby improving the stability of the installation of the driving member 121.

[0148] In one embodiment, the trigger member 16 may not be a trigger block, but may be a support shell 13. With this arrangement, it is unnecessary to separately arrange an additional trigger structure in the wiper strip assembly 1, thereby reducing manufacturing costs.

[0149] The scraper bar 11 may include a rotating shaft 15, which is rotatably connected to the support housing 13 via the rotating shaft 15. The state switching member 122 is capable of rotating the scraper bar 11 to switch between the first state and the second state. In other words, the state switching member 122 is capable of rotating the scraper bar 11 under the drive of the driving member 121.

[0150] In one embodiment, the state switching member 122 may include a first state switching member and a second state switching member. The first state switching member may be configured to restore the scraper strip 11 to the first state. The second state switching member may be configured to restore the scraper strip 11 to the second state.

[0151] like Figures 7 to 9 ,as well as Figures 11 to 13As shown, the second state switching member may include a driving swing arm 123. One end of the driving swing arm 123 may be connected to the driving member 121. Driven by the driving member 121, the driving swing arm 123 can push the scraper 11 to rotate, thereby switching the scraper 11 to the second state. Specifically, it can be understood that one end of the driving swing arm 123 may be connected to the driving member 121 and can rotate under the drive of the driving member 121. During this rotation, the driving swing arm 123 can contact the scraper 11, pushing the scraper 11 to rotate, thereby switching the scraper 11 to the second state. This arrangement eliminates the need to connect the second state switching member to the scraper 11. It only requires that the driving swing arm 123 contact the scraper 11 during rotation. This eliminates the need to connect the second state switching member to the scraper 11. It also prevents breakage at the connection between the second state switching member and the scraper 11, thereby increasing the service life of the scraper assembly 1.

[0152] The scraper bar 11 may further include a cam 111. The driving swing arm 123 may push the cam 111 to switch the scraper bar 11 to the second state. The present disclosure provides the cam 111 to facilitate the driving swing arm 123 pushing the scraper bar 11 during rotation, thereby making the rotation of the scraper bar 11 more stable.

[0153] The cam 111 can be a segmented cam 111. This configuration can reduce the space occupied by the drive swing arm 123 and the cam 111, thereby miniaturizing the scraper assembly 1 and leaving more space for other components of the cleaning device. However, the present invention is not limited to this. The cam 111 can also be a non-segmented cam 111 and can be configured according to actual circumstances, all of which are within the scope of protection of this disclosure.

[0154] In one embodiment, the driving swing arm 123 can maintain contact with the cam 111. This arrangement can improve the rotational stability of the scraper bar 11. Furthermore, this arrangement can also utilize the driving swing arm 123 to consistently apply a stopping force to the cam 111, ensuring that the scraper bar 11 does not shift after being switched into position. This ensures that the scraper bar 11 remains stable during operation, thereby improving the cleaning effect of the scraper bar 11.

[0155] In one embodiment, the support shell 13 may include: a first shell 131 and a second shell 132. The second shell 132 may be connected to the first shell 131, and the second shell 132 may extend in a direction away from the first shell 131. The above-mentioned driving member 121 may be installed on a side of the first shell 131 close to the second shell 132. The scraper 11 may be rotatably installed on a side of the first shell 131 away from the second shell 132. Therefore, the present disclosure installs the driving member 121 and the scraper 11 on two opposite sides of the first shell 131, respectively, which can facilitate the driving member 121 to drive the scraper 11. However, it is not limited to this, and the driving member 121 may also be installed on the second shell 132, which can be set according to actual conditions.

[0156] The first shell 131 may be provided with a first through hole 133 , and at least part of the driving device 12 may pass through the first through hole 133 to contact or connect with the scraper 11 , for example, part of the state switching member 122 may pass through the first through hole 133 to contact or connect with the scraper 11 .

[0157] Alternatively, at least a portion of the scraper strip 11 may pass through the first through hole 133 to contact or connect with the driving device 12 . For example, a portion of the cam 111 may pass through the first through hole 133 to contact the driving swing arm 123 .

[0158] In one embodiment of the present disclosure, the first state switching member may include: an elastic element. The elastic element may be connected to both the support shell 13 and the scraper 11. Moreover, when the scraper 11 is in the second state, the elastic element may have a restoring force inside. Thus, when the scraper 11 needs to switch from the second state to the first state, the restoring force inside the elastic element can be directly used to quickly restore the scraper 11 to the first state, without the need to use the driving member 121 for driving, thereby saving the production and use costs of the scraper assembly 1. At the same time, since the recovery process of the elastic element is relatively fast, the speed at which the scraper 11 switches to the first state can be increased.

[0159] In one embodiment, Figure 7 、 Figure 8 、 Figure 11 and Figure 12 As shown, the elastic element may include a tension spring 124. One end of the tension spring 124 may be connected to the support shell 13, and the other end may be connected to the scraper strip 11. For example, one end of the tension spring 124 may be connected to the second shell 132.

[0160] The elastic element may include at least two tension springs 124, which may be respectively connected to both ends of the scraper strip 11, thereby ensuring that both ends of the scraper strip 11 are subjected to force when switching states, thereby ensuring its stability when switching states.

[0161] In one embodiment, the first housing 131 may further include a second through-hole 134, and the scraper strip 11 may further include a connecting portion 112. A tension spring 124 may be connected to the connecting portion 112, and when the scraper strip 11 is switched to the first state, a portion of the connecting portion 112 may pass through the second through-hole 134. This arrangement facilitates the connection between the tension spring 124 and the connecting portion 112 and improves the stability of the connection between the tension spring 124 and the connecting portion 112.

[0162] In another embodiment, Figure 9 and Figure 13 As shown, the elastic element may include a torsion spring 125. The torsion spring 125 may be sleeved on the rotating shaft 15 and connected to the scraper strip 11. By providing the torsion spring 125, the torsional restoring force of the torsion spring 125 may be utilized to switch the scraper strip 11 to the first state.

[0163] The elastic element may include at least two torsion springs 125, which may be respectively mounted on both ends of the rotating shaft 15 and connected to the scraper strip 11. This arrangement ensures that both ends of the scraper strip 11 are subjected to force when switching between states, thereby also ensuring the stability of the scraper strip 11 when switching between states.

[0164] However, the elastic elements involved in the present disclosure may also include other types of elastic elements, such as rubber bands, etc., which can be selected and set according to actual needs, which are all within the scope of protection of the present disclosure.

[0165] In another embodiment, Figure 10 and Figure 14 As shown, the state switching member 122 may further include: a driving wheel 126 and a driven wheel. The driving wheel 126 may be rotatably connected to the driving member 121. The driven wheel 127 may be mounted on the rotating shaft 15, and the driven wheel 127 may be in contact with the driving wheel 126 to rotate under the drive of the driving wheel 126. In this way, when the driven wheel rotates under the drive of the driving wheel 126, the driven wheel 127 may drive the rotating shaft 15 to rotate, thereby driving the scraper 11 to rotate, so as to switch the scraper 11 between the first state and the second state. By providing the driving wheel 126 and the driven wheel 127, the present disclosure can more accurately control the rotation angle of the scraper 11, thereby making the position of the scraper 11 after the state switching more accurate.

[0166] For example: when the scraper 11 needs to be switched to the second state, the driving member 121 can rotate forward, at this time the driving wheel 126 can rotate forward under the drive of the driving member 121, and the driven wheel 127 can reverse under the action of the driving wheel 126, thereby switching the scraper 11 to the second state; when the scraper 11 needs to be switched to the first state, the driving member 121 can reverse, at this time the driving wheel 126 can reverse under the drive of the driving member 121, and the driven wheel 127 can rotate forward under the action of the driving wheel 126, thereby switching the scraper 11 to the first state.

[0167] The driving wheel 126 and the driven wheel 127 can both be gears, and the driving wheel 126 and the driven wheel 127 can mesh. This arrangement ensures that the driving force generated when the driving wheel 126 rotates can be accurately transmitted to the driven wheel 127, thereby improving the transmission efficiency of the driving force. In addition, this arrangement can avoid the problem of slippage between the driving wheel 126 and the driven wheel 127, thereby making the position of the scraper 11 more accurate after the state is switched. In addition, this arrangement can also use the meshing between the driving wheel 126 and the driven wheel 127 to limit the position of the scraper 11, thereby avoiding the problem of the scraper 11 rotating accidentally during operation.

[0168] However, the present invention is not limited thereto. The driving wheel 126 and the driven wheel 127 may not be gears, but may be other types of wheel-shaped structures, and the present disclosure does not impose any specific limitation thereto.

[0169] In another embodiment, the state switching member 122 may include a pull rod. One end of the pull rod may be connected to the driver 121, and the other end may be connected to the scraper 11 to pull the scraper 11 between the first and second states. Due to the high structural strength of the pull rod, configuring the state switching member 122 as a pull rod can increase the service life of the state switching member 122, thereby increasing the service life of the scraper assembly 1.

[0170] In another embodiment, the driving device 12 may be a lifting device to drive the scraper bar 11 to move away from or closer to the surface to be cleaned 3, so that the scraper bar 11 switches between the first state and the second state.

[0171] In this embodiment, the driving device 12 can be a structure in which a nut and a screw are matched. By rotating the nut, the nut can be moved along the screw, thereby driving the scraper 11 to move along the screw. However, the driving device 12 can also be a lift, etc., and can be configured according to actual needs.

[0172] In one embodiment of the present disclosure, Figure 3As shown, the scraper strip 11 is also configured to have a third state. When the scraper strip 11 is switched to the third state, the bottom of the scraper strip 11 can rotate toward the direction close to the cleaning working part 21, so that the bottom of the scraper strip 11 can be closer to the cleaning working part 21, so that the cleaning working part 21 can be used to clean the bottom of the scraper strip 11.

[0173] In this embodiment, if Figures 3 to 8 As shown, when the scraper bar 11 is switched to the third state, the bottom of the scraper bar 11 can contact the cleaning working part 21. Such an arrangement can improve the cleaning effect of the cleaning working part 21 on the scraper bar 11, so that the cleaning working part 21 can remove the dirt on the scraper bar 11 as much as possible.

[0174] In one embodiment, the state switching member 122 can be configured to switch the scraper strip 11 between a first state, a second state, and a third state. That is, the present disclosure can utilize the state switching member 122 to place the scraper strip 11 in the first state, the second state, or the third state.

[0175] When the state switching member 122 includes a first state switching member and a second state switching member, the second state switching member can be configured to switch the scraper blade 11 from the second state to the third state. For example, the driving swing arm 123 can be driven by the driving member 121 to rotate the scraper blade 11 to switch the scraper blade 11 to the third state. Furthermore, when the scraper blade 11 is in the third state, the elastic element can have a restoring force within it, which is used to switch the scraper blade 11 from the third state to the first state.

[0176] When the state switching member 122 includes a driving wheel 126 and a driven wheel 127, the driving member 121 can be used to drive the driving wheel 126 to rotate, and the driving wheel 126 can be used to drive the driven wheel 127 to rotate, so that the driven wheel 127 switches the scraper strip 11 to the third state.

[0177] When the state switching member 122 includes a pull rod, the driving member 121 can also be used to drive the pull rod to move, so as to pull the scraper strip 11 to switch between the first state, the second state and the third state.

[0178] It should be noted that the present disclosure has already described in detail the working principles and structures of various state switching components 122 in the aforementioned embodiments, so they will not be described in detail in this embodiment. You can refer to the description in the aforementioned embodiments, which is within the scope of protection of the present disclosure.

[0179] In one embodiment of the present disclosure, the driving angle of the driving member 121 can be pre-set. For example, three driving angles can be pre-set in the driving member 121, each of which corresponds to a state of the scraper 11, thereby further ensuring the accuracy of the position of the scraper 11 after switching states.

[0180] In one embodiment of the present disclosure, Figures 1 to 5 As shown, the scraper bar assembly 1 may further include a distance sensor 14. The distance sensor 14 may be configured to detect the distance between the cleaning main body 2 and the obstacle. When the cleaning main body 2 includes a cleaning working part 21, the distance sensor 14 may be configured to detect the distance between the cleaning working part 21 and the obstacle.

[0181] In one embodiment, the distance sensor 14 can be installed at the front end of the cleaning host 2. Such an arrangement can improve the stability of the installation of the distance sensor 14 and ensure the accuracy of the distance measurement of the distance sensor 14.

[0182] When the scraper assembly 1 is provided with at least two scrapers 11, there can be two distance sensors 14, and the two distance sensors 14 can be respectively installed at the front end and the rear end of the cleaning host 2 to respectively detect the distance between the front end of the cleaning host 2 and the obstacle and the distance between the rear end of the cleaning host 2 and the obstacle.

[0183] However, the present invention is not limited thereto. The distance sensor 14 may not be installed on the cleaning main unit 2. Instead, the distance sensor 14 may be installed on a position such as the supporting shell 13. The arrangement may be made according to actual needs.

[0184] Another aspect of the present disclosure provides a cleaning device. The cleaning device may be a floor scrubber, a floor sweeper, a floor sweeping robot, etc. Figures 1 to 14 As shown, the cleaning device may include: a cleaning main body 2 and a scraper assembly 1. The scraper assembly 1 may be the scraper assembly 1 described above, and the scraper assembly 1 may be installed on the cleaning main body 2.

[0185] It should be noted that the present disclosure has already described in detail the specific structure and beneficial effects of the scraper strip assembly 1 in the previous embodiment, so in this embodiment, the specific structure and beneficial effects of the scraper strip assembly 1 will not be repeated. You can refer to the specific description in the previous embodiment, which is all within the scope of protection of the present disclosure.

[0186] The cleaning device provided by the present disclosure includes the scraper bar assembly 1 described above, and the scraper bar 11 in the scraper bar assembly 1 described above can be switched between a first state and a second state according to the movement direction of the cleaning host 2 and the distance between the cleaning host 2 and the obstacle.

[0187] With such a configuration, the present invention can accurately judge whether it is currently necessary to clean the area near the obstacle based on the movement direction of the cleaning host 2 and the distance between the cleaning host 2 and the obstacle. After judging that it is currently necessary to clean the area near the obstacle, the scraper 11 is accurately switched to the second state, so that the distance between the scraper 11 and the surface to be cleaned 3 is closer, thereby being able to remove dirt, water stains, etc. near the obstacle.

[0188] Moreover, after determining that there is currently no need to clean the area near the obstacle, the scraper 11 can be maintained in the first state, or the scraper 11 can be switched from the second state to the first state, so that the scraper 11 is farther away from the surface 3 to be cleaned, thereby avoiding the scraper 11 being accidentally put down when the cleaning host 2 is not close to the obstacle and affecting the normal operation of the cleaning host 2.

[0189] And / or, the wiper strip assembly 1 may include: a wiper strip 11 and a trigger member 16 , and the wiper strip 11 may be configured to switch between a first state and a second state when the trigger member 16 is triggered.

[0190] With this arrangement, the state of the scraper bar 11 can be switched as needed, that is, when it is necessary to clean dirt, water stains, etc. on the cleaning surface 3, the trigger member 16 can be triggered to switch the scraper bar 11 to the second state, so that cleaning can be performed using the scraper bar 11. When it is not necessary to clean dirt, water stains, etc. on the cleaning surface 3, the trigger member 16 can be triggered to switch the scraper bar 11 to the first state, so as to facilitate cleaning operations such as cleaning the main body 2.

[0191] In one embodiment of the present disclosure, the cleaning working part 21 may be a roller brush, but is not limited thereto. The cleaning working part 21 may also be a side brush, etc., and may be configured according to actual needs.

[0192] Another aspect of the present disclosure provides a cleaning system. The cleaning system may include: a base station and a cleaning device. The cleaning device may be the cleaning device described above, and the cleaning device may be docked with the base station.

[0193] It should be noted that the present disclosure has already provided a detailed description of the specific structure and beneficial effects of the cleaning equipment in the previous embodiment, so in this embodiment, the specific structure and beneficial effects of the cleaning equipment will not be repeated. You can refer to the specific description in the previous embodiment, which is all within the scope of protection of the present disclosure.

[0194] The cleaning system provided by the present disclosure includes the cleaning equipment described above, such as Figures 1 to 14As shown, the above-mentioned cleaning device includes the above-mentioned scraper assembly 1, and the scraper 11 in the above-mentioned scraper assembly 1 can be switched between the first state and the second state according to the movement direction of the cleaning host 2 and the distance between the cleaning host 2 and the obstacle.

[0195] With such a configuration, the present invention can accurately judge whether it is currently necessary to clean the area near the obstacle based on the movement direction of the cleaning host 2 and the distance between the cleaning host 2 and the obstacle. After judging that it is currently necessary to clean the area near the obstacle, the scraper 11 is accurately switched to the second state, so that the distance between the scraper 11 and the surface to be cleaned 3 is closer, thereby being able to remove dirt, water stains, etc. near the obstacle.

[0196] Moreover, after determining that there is currently no need to clean the area near the obstacle, the scraper 11 can be maintained in the first state, or the scraper 11 can be switched from the second state to the first state, so that the scraper 11 is farther away from the surface 3 to be cleaned, thereby avoiding the scraper 11 being accidentally put down when the cleaning host 2 is not close to the obstacle and affecting the normal operation of the cleaning host 2.

[0197] And / or, the wiper strip assembly 1 may include: a wiper strip 11 and a trigger member 16 , and the wiper strip 11 may be configured to switch between a first state and a second state when the trigger member 16 is triggered.

[0198] With this arrangement, the state of the scraper bar 11 can be switched as needed, that is, when it is necessary to clean dirt, water stains, etc. on the cleaning surface 3, the trigger member 16 can be triggered to switch the scraper bar 11 to the second state, so that cleaning can be performed using the scraper bar 11. When it is not necessary to clean dirt, water stains, etc. on the cleaning surface 3, the trigger member 16 can be triggered to switch the scraper bar 11 to the first state, so as to facilitate cleaning operations such as cleaning the main body 2.

[0199] In one embodiment of the present disclosure, when the cleaning device is docked with the base station, the scraper bar 11 can be switched to a third state. Specifically, when the cleaning device is docked with the base station, it can be considered to be in cleaning mode or standby mode, and the cleaning unit 21 is therefore idle and not required to perform cleaning work. Switching the scraper bar 11 to the third state allows the cleaning unit 21 to clean the scraper bar 11 while idle, thus avoiding any disruption to the normal cleaning work of the cleaning unit 21. This configuration also ensures that the scraper bar 11 is clean the next time the cleaning device performs cleaning work.

[0200] Other embodiments of the present disclosure will readily occur to those skilled in the art after considering the specification and practicing the utility model disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the appended claims.
