Description

Technical Field

[0001] The present application relates to the technical field of floor cleaning, and in particular to a cleaning device. Background Art

[0002] Common cleaning devices include vacuum cleaners, mops and sweeping robots. Vacuum cleaners and mops require manual operation, while sweeping robots can automatically monitor the environment through internally set programs and automatically clean the floor.

[0003] Existing sweeping robots usually include a roller assembly and a sewage tank. The roller assembly includes a roller, a roller mop and a scraper. The roller mop is arranged on the outer periphery of the roller and rotates with the rotation of the roller to clean the floor. The scraper is in contact with the roller mop so that the scraper can scrape off the sewage and stains on the roller mop. The scraped sewage enters the water receiving groove of the sewage tank through the diversion channel on the scraper, and finally the sewage enters the sewage tank for centralized treatment of the sewage. In some existing sweeping robots, in order to enable the sweeping robot to clean the corners, the roller assembly usually has a function that can be partially extended from the sweeping robot so that the roller assembly can also clean the stolen goods in the corners.

[0004] However, when part of the roller assembly extends out of the sweeping robot to clean the floor, friction is easily generated between the scraping bar and the sewage tank, which eventually causes the scraping bar or the water receiving trough to be worn. Utility Model Content

[0005] The main purpose of the present application is to provide a cleaning device to at least solve the problem of easy wear between the scraper bar and the side wall of the water receiving trough of the cleaning device in the prior art.

[0006] According to one aspect of the present application, there is provided a cleaning device, comprising:

[0007] A main body, wherein a mounting groove is formed at the bottom of the main body;

[0008] A cleaning assembly, the cleaning assembly comprising a cleaning member and a scraper strip, the cleaning member being rotatably connected in the mounting groove and being reciprocating along a first direction, and the first end of the scraper strip abutting against the cleaning member;

[0009] A water receiving trough, which is arranged on the main body and located outside the mounting groove;

[0010] The second end of the scraper bar extends into the water receiving groove, and a first gap is formed between the side wall of the water receiving groove close to the scraper bar and the scraper bar.

[0011] Further, in the initial state, the minimum width A of the first gap satisfies the relationship: 0.3mm≤A≤0.5mm.

[0012] Furthermore, the side wall of the water receiving trough close to the scraper strip includes a hard reinforcement section and a flexible extension section connected to each other, the flexible extension section is arranged on the top of the hard reinforcement section, and the first gap is provided between the scraper strip and the flexible extension section.

[0013] Furthermore, a surface of the scraper strip close to the flexible extension section is a first curved surface, and a surface of the flexible extension section close to the scraper strip is a second curved surface matched with the first curved surface.

[0014] Furthermore, a second gap is provided between the cleaning member and the flexible extension section.

[0015] Furthermore, in the initial state, the minimum width B of the second gap satisfies the relationship: 2mm≤B≤3mm.

[0016] Furthermore, along the first direction, a water outlet channel is opened in the middle of the scraper strip, and the water outlet channel is communicated with the water receiving trough.

[0017] Furthermore, the scraper strip can reciprocate along the first direction, and along the height direction of the cleaning device, the projection surface of the water outlet channel is always located in the projection surface of the water receiving trough.

[0018] Furthermore, at least one reinforcing rib is provided in the water outlet channel, and the at least one reinforcing rib divides the water outlet channel into at least two water outlet holes.

[0019] Further, along the first direction, the maximum width C of the water outlet channel and the maximum width D of the scraper strip satisfy the relationship: 0.35≤C / D≤0.4.

[0020] Compared with the prior art, the cleaning component of the present application sets a first gap between the side wall of the water receiving trough close to the scraper bar and the scraper bar, so that there is a certain gap between the scraper bar and the side wall of the water receiving trough, thereby avoiding friction between the scraper bar and the side wall of the water receiving trough when the cleaning element reciprocates along the first direction, ultimately causing damage to the scraper bar or the water receiving trough.

[0033] See also Figures 1 to 6 As shown, according to an embodiment of the present application, a cleaning device is provided, including a main body 10, a cleaning assembly 20 and a water receiving tank 30.

[0034] The bottom of the main body 10 is provided with a mounting groove 11. The cleaning assembly 20 includes a cleaning member 21 and a scraper 22. The cleaning member 21 is rotatably connected to the mounting groove 11 and can be moved along a first direction (such as the attached Figure 2 The scraper 22 reciprocates in the X direction, and the first end of the scraper 22 abuts against the cleaning member 21. The water receiving groove 30 is provided on the main body 10 and is located outside the mounting groove 11. The second end of the scraper 22 extends into the water receiving groove 30, and a first gap 60 is formed between the side wall of the water receiving groove 30 close to the scraper 22 and the scraper 22.

[0035] Specifically, when the cleaning device is working, the cleaning member 21 rotates in the installation groove 11 to clean the stains on the ground, and the first end of the scraper strip 22 abuts against the cleaning member 21 to scrape off the stains and sewage on the cleaning member 21, and collects the sewage into the water receiving tank 30. At the same time, in this embodiment, the cleaning member 21 can reciprocate along the first direction, so that a part of the cleaning member 21 protrudes from the outer edge of the main body 10, so that the cleaning device can clean the corners.

[0036] Compared with the prior art, the cleaning component 20 of this embodiment is provided with a first gap 60 between the side wall of the water receiving trough 30 close to the scraper bar 22 and the scraper bar 22, so that there is a certain gap between the scraper bar 22 and the side wall of the water receiving trough 30, thereby avoiding friction between the scraper bar 22 and the side wall of the water receiving trough 30 when the cleaning element 21 reciprocates along the first direction, which eventually causes damage to the scraper bar 22 or the water receiving trough 30.

[0037] In some embodiments, the cleaning member 21 includes a drum, a drum mop is arranged on the outer periphery of the drum, and the scraper bar 22 abuts against the drum mop. The cleaning assembly 20 also includes a motor 23, the output end of the motor 23 is arranged in the drum, and drives the drum to rotate around its own axial direction. The cleaning device also includes a sewage tank 40, which is arranged at the bottom of the main body 10, and the sewage tank 40 is connected to the water receiving trough 30. Specifically, a suction assembly 50 is arranged between the water receiving trough 30 and the sewage tank 40. When the sewage scraped by the scraper bar 22 enters the water receiving trough 30, the sewage in the water receiving trough 30 is sucked into the sewage tank 40 through the suction assembly 50. In some embodiments, the water receiving trough 30, the suction assembly 50 and the sewage tank 40 are integrally formed.

[0038] As attached Figure 5 As shown, in the initial state, the minimum width A of the first gap 60 satisfies the relationship: 0.3 mm ≤ A ≤ 0.5 mm.

[0039] It is worth noting that the "initial state" refers to the state in which the cleaning device is not started and the cleaning member 21 is completely located in the mounting groove 11. At this time, the minimum spacing A between the side wall of the water receiving trough 30 and the scraper 22 should satisfy the relationship: 0.3mm≤A≤0.5mm. When A satisfies the above relationship, the spacing between the side wall of the water receiving trough 30 and the scraper 22 will not be too large, thereby avoiding the cleaning device from having a large overall volume, resulting in low space utilization of the cleaning device. At the same time, when A is within the above range, the spacing between the side wall of the water receiving trough 30 and the scraper 22 is moderate, and the scraper 22 will not contact the side wall of the water receiving trough 30 when shaking, causing interference between the water receiving trough 30 and the scraper 22. When A is less than 0.3mm, the gap between the scraper 22 and the side wall of the water receiving trough 30 is too small, and the scraper 22 may shake and interfere with the side wall of the water receiving trough 30 when the cleaning device is running. When A is greater than 0.5 mm, the distance between the side wall of the water receiving groove 30 and the scraper strip 22 is too large, which increases the overall volume of the cleaning device and reduces the space utilization of the cleaning device. The value of A can be 0.3 mm, 0.32 mm, 0.34 mm, 0.36 mm, 0.38 mm, 0.4 mm, 0.42 mm, 0.44 mm, 0.46 mm, 0.48 mm and 0.5 mm.

[0040] In addition, when the cleaning device is cleaning the floor, it may be shaken by external forces, and the shaking of the cleaning device causes the scraper bar 22 to shake. When the scraper bar 22 shakes too much, it may cause the scraper bar 22 to contact and interfere with the side wall of the water receiving trough 30, and eventually damage the scraper bar 22 or the side wall of the water receiving trough 30. In order to solve the above problem, in this embodiment, the side wall of the water receiving trough 30 near the scraper bar 22 includes a hard reinforcement section 311 and a flexible extension section 312 connected to each other, and the flexible extension section 312 is arranged on the top of the hard reinforcement section 311, and there is a first gap 60 between the scraper bar 22 and the flexible extension section 312.

[0041] Specifically, when the scraper bar 22 shakes too much, so that the scraper bar 22 can contact the side wall of the water receiving trough 30, since the top of the side wall of the water receiving trough 30 is a flexible extension section 312, the flexible extension section 312 has good buffering performance. When the flexible extension section 312 collides with the scraper bar 22, damage to the scraper bar 22 can be avoided to a certain extent. In this embodiment, the flexible extension section 312 includes at least one of a rubber strip and a silicone strip. In addition, the hard reinforcement section 311 at the bottom of the flexible extension section 312 can improve the structural strength of the side wall of the water receiving trough 30 close to the scraper bar 22.

[0042] As attached Figure 5 As shown, a side of the scraper strip 22 close to the flexible extension section 312 is a first arcuate surface 221 , and a side of the flexible extension section 312 close to the scraper strip 22 is a second arcuate surface 3121 matched with the first arcuate surface 221 .

[0043] Specifically, when the scraper strip 22 shakes and contacts the flexible extension section 312, the first curved surface 221 and the second curved surface 3121 fit together to increase the contact area between the flexible extension section 312 and the scraper strip 22, thereby reducing the stress inside the flexible extension section 312 when the scraper strip 22 hits the flexible extension section 312, thereby increasing the service life of the flexible extension section 312.

[0044] In order to avoid friction between the cleaning member 21 and the flexible extension section 312 or the flexible extension section 312 coming into contact with the cleaning member 21 after the scraper strip 22 collides with the flexible extension section 312, causing the cleaning member 21 to get stuck. In this embodiment, there is a second gap 70 between the cleaning member 21 and the flexible extension section 312. Since the second gap 70 is provided between the cleaning member 21 and the flexible extension section 312, the structure of this embodiment can avoid collision or friction between the flexible extension section 312 and the cleaning member 21 to a certain extent.

[0045] As attached Figure 5 As shown, in the initial state, the minimum width B of the second gap 70 satisfies the relationship: 2mm≤B≤3mm.

[0046] Specifically, when the cleaning device is not working and the cleaning member 21 is completely located in the installation groove 11, the minimum width B of the second gap 70 should satisfy the relationship: 2mm≤B≤3mm. When B satisfies the above relationship, the minimum spacing between the cleaning member 21 and the flexible extension section 312 will not be too large, which will make the overall volume of the cleaning device too large, resulting in too low space utilization of the cleaning device. At the same time, the minimum spacing between the cleaning member 21 and the flexible extension section 312 will not be too small, so that when the flexible extension section 312 is hit by the scraper 22, the flexible extension section 312 will deform in the direction close to the cleaning member 21, which may eventually cause the flexible extension section 312 to press against the cleaning member 21 and cause the cleaning member 21 to be stuck. When B is less than 2mm, the minimum spacing between the flexible extension section 312 and the scraper 22 is too close, which may cause interference or wear between the flexible extension section 312 and the cleaning member 21. When B is greater than 3 mm, the second gap 70 is too large, which increases the overall volume of the cleaning device, increasing the manufacturing cost on the one hand; on the other hand, the excessive volume of the cleaning device may reduce the adaptability of the cleaning device. The value of B can be 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm and 3 mm.

[0047] Furthermore, along the first direction, a water outlet channel 222 is opened in the middle of the scraper strip 22 , and the water outlet channel 222 is communicated with the water receiving tank 30 .

[0048] Specifically, the first end of the scraper bar 22 abuts against the cleaning member 21. When the cleaning member 21 is working, the first end of the scraper bar 22 can scrape off the sewage on the cleaning member 21, and the scraped sewage enters the water receiving tank 30 through the water outlet channel 222 in the middle of the scraper bar 22. In addition, since the cleaning member 21 in this embodiment can move along the first direction, that is, the cleaning member 21 can protrude from the outer edge of the cleaning device along the first direction, if the water outlet channel 222 is set at the end of the scraper bar 22 close to the outer edge protruding from the cleaning device, the water outlet channel 222 may protrude from the outer edge of the cleaning device, and ultimately cause the sewage to be unable to enter the water receiving tank, so in this embodiment, the water outlet channel 222 is set in the middle of the scraper bar 22. In some embodiments, the cleaning member 21 can move along the first direction, or move in a direction opposite to the first direction, so that the cleaning member 21 protrudes from the outer edge of the cleaning device, so it is a preferred solution to set the water outlet channel 222 in the middle of the scraper bar 22.

[0049] In addition, when the scraper bar 22 can only pass through the cleaning device along the first direction, the water outlet channel 222 can also be set at the end of the scraper bar 22 in the opposite direction to the first direction to prevent the water outlet channel 222 from protruding from the outer edge of the cleaning device.

[0050] Furthermore, the scraper strip 22 can reciprocate along the first direction and along the height direction of the cleaning device (such as the attached Figure 1 The projection surface of the water outlet channel 222 is always located in the projection surface of the water receiving tank 30. That is, the position and width of the water outlet channel 222 should be set so that when the scraper 22 reciprocates in the first direction, the sewage flowing out of the water outlet channel 222 can always enter the water receiving tank 30.

[0051] Further, along the first direction, the maximum width C of the water outlet channel 222 and the maximum width D of the scraper bar 22 satisfy the relationship: 0.35≤C / D≤0.4. When C / D satisfies the above range, the maximum width C of the water outlet channel 222 will not account for too large a proportion of the maximum width D of the scraper bar 22, resulting in too low a structural strength of the scraper bar 22. At the same time, when C / D satisfies the above range, the proportion of the water outlet channel 222 on the scraper bar 22 will not be too small, so that the sewage scraped by the scraper bar 22 cannot flow into the water receiving trough 30 through the water outlet channel 222 in time. When C / D is less than 0.35, the maximum width C of the water outlet channel 222 accounts for too small a proportion of the maximum width D of the scraper bar 22, which may result in the sewage scraped by the scraper bar 22 cannot be discharged from the water outlet channel 222 in time. When C / D is greater than 0.4, the maximum width C of the water outlet channel 222 accounts for too large a proportion of the maximum width D of the scraper bar 22, resulting in too low a structural strength of the scraper bar 22, making the scraper bar 22 easily damaged. The values ​​of C / D can be 0.35, 0.36, 0.37, 0.38, 0.39 and 0.4.

[0052] In a specific embodiment, the maximum width D of the scraper bar 22 is 267 mm, the maximum width C of the water outlet channel 222 is 100 mm, and C / D is 0.37. It should be noted that, since the cleaning device has a variety of models of different sizes, the maximum width C of the water outlet channel 222 and the maximum width D of the scraper bar 22 should be set according to actual manufacturing requirements, but the ratio of C to D should satisfy the above relationship as much as possible.

[0053] Furthermore, at least one reinforcing rib 223 is disposed in the water outlet channel 222 , and the at least one reinforcing rib 223 divides the water outlet channel 222 into at least two water outlet holes 2221 .

[0054] Specifically, the reinforcing ribs 223 can strengthen the structural strength of the scraper bar 22, and prevent the scraper bar 22 from being easily damaged after being subjected to external forces due to the setting of the water outlet channel 222. In addition, the reinforcing ribs 223 divide the water outlet channel 222 into a plurality of water outlet holes 2221, and the sewage scraped by the scraper bar 22 can flow into the water receiving tank 30 through the plurality of water outlet holes 2221 at the same time. Figure 6As shown, a reinforcing rib 223 is provided in the water outlet channel 222, so that the water outlet channel 222 is divided into two water outlet holes 2221. Of course, in some other embodiments, a plurality of reinforcing ribs 223 may be provided in the water outlet channel 222 to further improve the structural strength of the scraper strip 22.

[0055] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0056] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0057] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
