[0038] With the continuous advancement and development of science and technology, people have higher expectations for their living standards. Cleaning is an essential daily routine in people's lives. Most existing cleaning components are equipped with scraping bars. When the cleaning component is in use, the height of the scraping bar relative to the cleaning surface often changes. When the cleaning component is subjected to high pressure or the cleaning surface is partially convex, the scraping bar is easily deformed under high pressure, affecting the cleaning effect. When the height of the cleaning surface is lowered, the contact force between the scraping bar and the cleaning surface becomes smaller or there is no contact with the cleaning surface, which also affects the cleaning effect.
[0039] In order to solve the technical problem that the scraper 30 of the existing cleaning device affects the cleaning effect due to the change in the force and the height of the cleaning surface 40, the present application provides a scraper 30 and a cleaning device, the cleaning device is equipped with the scraper 30, the scraper 30 has the scraper body 31, the limiting portion 32, the elastic portion 33 and the connecting portion 34, the scraper body 31 is used to slide and connect the cleaning device, when the pressure on the scraper 30 increases during the cleaning process or the height of the cleaning surface 40 rises relative to the scraper 30, the scraper body 31 can adjust its own position according to the pressure to avoid large deformation, ensure the contact angle of the scraper body 31 relative to the cleaning surface 40, and ensure the cleaning of the scraper 30. In order to achieve a cleaning effect, the limiting portion 32 is installed on the scraper body 31, and the limiting portion 32 is used to limit the separation of the scraper body 31 from the cleaning device. The elastic portion 33 is connected to the scraper body 31, and the connecting portion 34 is connected to the elastic portion 33. The connecting portion 34 is used to engage with the cleaning device. After the scraper 30 is installed in the cleaning device, the elastic portion 33 bends and applies internal stress to the scraper body 31, so that the scraper body 31 squeezes the cleaning surface 40; when the height of the cleaning surface 40 is lowered, the elastic portion 33 can drive the scraper body 31 to move toward the cleaning surface 40, adjust the position of the scraper body 31, ensure the contact force between the scraper body 31 and the cleaning surface 40, and ensure the cleaning effect.
[0040] Figure 1 is a schematic structural diagram of the scraper strip 30 according to an exemplary embodiment. Figure 2 FIG2 is a schematic diagram showing a cleaning device according to an exemplary embodiment, wherein the scraper bar 30 is in a lower position relative to the cleaning surface 40. Figure 3 1 is a schematic diagram showing a cleaning device according to an exemplary embodiment, in which the scraper bar 30 is at a high position relative to the cleaning surface 40 .
[0041] refer to Figure 1-3 As shown, the present application provides a scraper 30 and a cleaning device, the cleaning device is equipped with the scraper 30, and the cleaning device also includes the cleaning body 10 and the shell 20. The cleaning body 10 is installed in the shell 20. According to the understanding of those skilled in the art, the cleaning body 10 includes a roller brush.
[0042] like Figure 2-3 The housing 20 is provided with the slide groove 21 and the card groove 22 for installing the scraper 30. The slide and the card groove 22 are arranged in parallel, and the notch of the slide groove 21 and the notch of the card groove 22 are at the same horizontal height relative to the ground.
[0043] The scraper 30 includes the scraper body 31, the limiting portion 32, the elastic portion 33 and the connecting portion 34. The scraper body 31 includes the sliding portion 311 and the cleaning portion 312. The sliding portion 311 is connected to the cleaning portion 312, wherein the limiting portion 32 is connected to the sliding portion 311. The scraper 30 is slidably installed in the slide groove 21 through the sliding portion 311. The limiting portion 32 is used to limit the sliding portion 311 from escaping from the slide groove 21. The limiting portion 32 is connected to one end of the sliding portion 311 away from the cleaning portion 312, which can increase the sliding length of the sliding portion 311 in the slide groove 21.
[0044] The elastic portion 33 is connected to the scraper body 31. In the present application, the elastic portion 33 is connected to the portion between the sliding portion 311 and the cleaning portion 312, that is, the sliding portion 311 and the cleaning portion 312 are respectively located on opposite sides of the elastic portion 33. After the scraper 30 is installed on the cleaning device, the elastic portion 33 is located outside the slide groove 21, and the elastic portion 33 and the limiting portion 32 are respectively located on opposite sides of the sliding portion 311 to limit the sliding range of the sliding portion 311.
[0045] The elastic portion 33 is made of rubber, which has a certain toughness and is easy to recover after being bent.
[0046] The connecting portion 34 is connected to the elastic portion 33 , and is used for engaging with the cleaning device. Preferably, the connecting portion 34 is located on a side of the elastic portion 33 away from the scraper body 31 .
[0047] In the present application, the connecting portion 34 is engaged with the card slot 22, the scraper body 31 is slidably engaged with the slide slot 21, and the elastic portion 33 is provided between the connecting portion 34 and the scraper body 31. Since the slide slot 21 and the card slot 22 are arranged in parallel, after the scraper 30 is installed in the cleaning device, Figure 1 As shown, the elastic portion 33 is bent, and the elastic portion 33 applies internal stress to the scraper body 31 , so that the scraper body 31 presses the cleaning surface 40 .
[0048] The present application solution utilizes the internal stress of the elastic portion 33 after deformation, so that the scraper body 31 exerts a certain pressure on the cleaning surface 40, ensuring that the scraper body 31 is in close contact with the cleaning surface 40 and ensuring a cleaning effect.
[0049] refer to Figure 1 As shown, in the natural state when the slide bar is not installed, in the cross section perpendicular to the length direction of the scraper bar 30, the cross-sectional shape of the elastic portion 33 and the cross-sectional shape of the scraper bar body 31 are respectively strip-shaped and intersecting, that is, the cross-sectional length direction of the elastic portion 33 intersects with the cross-sectional length direction of the body portion.
[0050] The degree of bending of the scraper strip 30 affects the internal stress it exerts on the scraper strip body 31 within a certain range. The cross-sectional length of the elastic portion 33 is oriented in a first direction, while the cross-sectional length of the scraper strip body 31 is oriented in a second direction. The angle formed by the first and second directions, with the opening facing the cleaning side of the scraper strip body 31, is α, with a range of 60°≤α≤120°. Within this angle range, after the scraper strip 30 is installed in the housing 20, the elastic portion 33 bends, transferring the internal stress of the elastic portion 33 to the scraper strip body 31, allowing the scraper strip body 31 to better contact the cleaning surface 40 and ensuring the cleaning effect of the scraper strip 30. As understood by those skilled in the art, the sliding groove 21 and the engaging groove 22 are oriented in the same direction, while the installation direction of the scraper strip body 31 intersects the installation direction of the connecting portion 34. Therefore, after either the scraper strip body 31 or the connecting portion 34 is installed, the elastic portion 33 must be bent when installing the other to achieve installation of the scraper strip 30.
[0051] In the present application, the connecting portion 34 is further provided with a groove 341 for engaging with the card slot 22. Figure 2As shown, the housing 20 is provided with a convex portion at the notch of the card slot 22 , and the groove 341 is used to cooperate with the convex portion to prevent the connecting portion 34 from falling out of the card slot 22 , thereby improving the stability of the card slot 22 .
[0052] Figure 2 The dotted line in the figure represents the cleaning surface 40, which can be the ground. When the pressure of the cleaning device on the ground is small, the compression of the bristles of the roller brush is small, and the scraper 30 is in a low position. At this time, the elastic part 33 bends and applies internal stress to the scraper body 31. The scraper body 31 slides toward the outside of the shell 20 and slides to the extreme position. When the scraper body 31 is squeezed into contact with the ground, since the scraper body 31 is subjected to the internal stress from the elastic part 33, the scraper body 31 will be in close contact with the cleaning surface 40 to ensure the cleaning effect.
[0053] Figure 3 The middle dashed line represents the cleaning surface 40, which can be the ground. When the cleaning device exerts greater pressure on the ground, the bristles of the roller brush are compressed significantly, the scraper bar 30 is in a high position, and the ground's squeezing force on the scraper bar body 31 is greater than the internal stress of the elastic portion 33 on the scraper bar body 31. The sliding portion 311 of the scraper bar body 31 slides toward the interior of the housing 20 and slides to its limit position. The scraper bar body 31 adjusts its position based on the pressure, avoiding significant deformation and ensuring the contact angle of the scraper bar body 31 on the cleaning surface 40, thereby ensuring the cleaning effect of the scraper bar 30.
[0054] Furthermore, after the scraper 30 is installed in the shell 20, the elastic portion 33 always applies internal stress to the scraper body 31, and when the scraper body 31 moves to different positions, the magnitude of the internal stress is different, so that the scraper body 31 can be in close contact with the cleaning surface 40 to ensure the cleaning effect.
[0055] When the squeezing force of the cleaning device on the cleaning surface 40 increases, the scraper 30 can slide toward the inside of the shell 20, and the scraper body 31 adjusts its own position according to the pressure sliding to avoid large deformation, thereby ensuring the contact angle of the scraper body 31 on the cleaning surface 40 and ensuring the cleaning effect of the scraper 30.
[0056] In the present application, the scraper 30 can be used for scraping water. When the pressure of the cleaning device on the cleaning surface 40 is relatively small, the compression of the bristles of the roller brush is relatively small. The scraper body 31 is in close contact with the cleaning surface 40 due to the internal stress of the elastic part 33. When the pressure of the cleaning device on the cleaning surface 40 increases, the compression of the bristles of the roller brush is relatively large. The scraper 30 slides toward the inner part of the shell 20 under the squeezing force of the ground. The scraper body 31 adjusts its own position according to the pressure sliding to avoid large deformation, thereby ensuring the contact angle of the scraper body 31 with the cleaning surface 40, and the elastic part 33 continues to apply internal stress to the scraper body 31 to ensure that the scraper body 31 is in close contact with the cleaning surface 40, thereby ensuring the wiping effect.
[0057] In the present application, the scraper strip 30 may be made of rubber material, and the scraper strip 30 is formed by integral injection molding.
[0058] In some other embodiments, only the elastic portion 33 may be made of elastic rubber material, the scraper strip body 31 may be made of hard plastic, the connecting portion 34 may be made of hard plastic or a metal structure, and the connecting portion 34 may be snap-fitted with the shell 20, or may be fixedly connected to the shell 20 by screw fastening. According to the understanding of those skilled in the art, an existing installation method with a fixed connection function and easy disassembly and assembly may be selected.
[0059] In summary, the present invention provides a scraper 30 and a cleaning device, the cleaning device includes the shell 20 and the cleaning body 10 installed on the shell 20, the cleaning body 10 includes a roller brush, the shell 20 is installed with the scraper 30, the shell 20 is provided with the card slot 22 and the slide 21, the card slot 22 and the slide 21 are arranged in parallel, and the mounting openings of the card slot 22 and the slide 21 are in the same direction, including the connecting portion 34 and the scraper body 31, The elastic portion 33 is provided between the scraper strip body 31 and the connecting portion 34. The scraper strip body 31 slides in cooperation with the slide groove 21, and the connecting portion 34 is used to be fixedly connected with the card slot 22. In the present application, the installation direction of the scraper strip body 31 intersects with the installation direction of the elastic portion 33. Therefore, after the installation of either the scraper strip body 31 or the connecting portion 34 is completed, the elastic portion 33 must be bent when installing the other one to achieve the installation of the scraper strip 30.
[0060] refer to Figure 2 When the pressure of the cleaning device on the cleaning surface 40 is small, the compression amount of the bristles of the roller brush is small, and the scraper body 31 is in close contact with the cleaning surface 40 due to the internal stress of the elastic portion 33; Figure 3When the pressure of the cleaning device on the cleaning surface 40 increases, the bristles of the roller brush are compressed to a greater extent, and the scraper 30 slides toward the inner portion of the shell 20 due to the squeezing force of the ground. The scraper body 31 adjusts its position according to the pressure sliding to avoid large deformation, thereby ensuring the contact angle of the scraper body 31 with the cleaning surface 40, and the elastic part 33 continues to apply internal stress to the scraper body 31, ensuring that the scraper body 31 is in close contact with the cleaning surface 40, thereby ensuring the wiping effect.
