Description

Technical Field

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

[0002] The cleaning devices currently on the market include floor scrubbers, sweeping robots and multifunctional cleaning stations, wherein the multifunctional cleaning station cleans the floor by means of a drum and a drum mop sleeved on the outer circumference of the drum, and a scraper is also provided on the drum, which abuts against the drum mop to scrape off stains and dirty water on the drum mop.

[0003] In the existing multifunctional cleaning station, the scraper is usually a flat scraper, which presses against the roller mop and generates a large friction force with the roller mop, which can easily cause the roller to get stuck or the roller mop to wear. Utility Model Content

[0004] The main purpose of the present application is to provide a cleaning assembly and a cleaning device to at least solve the problem of the roller getting stuck or the roller mop being worn in the prior art.

[0005] According to one aspect of the present application, a cleaning assembly is provided, comprising:

[0006] main body;

[0007] A cleaning component, wherein the cleaning component is arranged at the bottom of the main body;

[0008] A scraper component is installed on the main body and is located outside the cleaning component. The scraper component includes a scraper. The scraper has an arc segment. The arc segment abuts against the cleaning component, and the extension direction of the arc segment near the end of the cleaning component deviates from the cleaning component.

[0009] Furthermore, the scraper also has a straight section, which is arranged at the end of the arc segment away from the cleaning component. The tangent passing through the endpoint of the end of the arc segment away from the straight section and tangent to the arc segment is the first tangent, and the angle M between the first tangent and the straight section satisfies the relationship: 80°≤M≤87°.

[0010] Further, the arc segment has a first arc surface close to the cleaning component and a second arc surface away from the first arc surface;

[0011] The curvature radius R1 of the first arc-shaped surface satisfies the relationship: 3.5 mm ≤ R1 ≤ 4 mm; and / or,

[0012] The curvature radius R2 of the second arc-shaped surface satisfies the relationship: 2.3 mm ≤ R2 ≤ 2.5 mm.

[0013] Furthermore, a distance I between an end of the arc segment facing away from the straight segment and an upper surface of the straight segment satisfies the relationship: 5.2 mm ≤ I ≤ 5.6 mm.

[0014] Furthermore, the scraper component also includes a water spray plate group, which is arranged on the top of the scraper, and a flow channel is opened in the water spray plate group. A plurality of water spray holes are arranged on the side of the water spray plate group close to the cleaning component, and the plurality of water spray holes are arranged along the extension direction of the cleaning component, and the water spray holes are connected to the flow channel.

[0015] Furthermore, the scraper component also includes a dustproof pad, and the dustproof pad is arranged between the scraper and the water spray plate group.

[0016] Furthermore, a first limiting section is provided on one side of the bottom of the water spray plate group close to the cleaning component, and the first limiting section is stopped on the straight section and is located on the outer side of one end of the dustproof pad close to the cleaning component.

[0017] Furthermore, a limiting groove is provided on a side of the top of the dustproof pad away from the cleaning component;

[0021] Compared with the prior art, the end of the scraper close to the cleaning component in the present application is an arc segment, and the extension direction of the end of the arc segment close to the cleaning component deviates from the cleaning component. Compared with the straight scraper in the prior art, the direction of the force applied by the arc segment to the roller mop is more biased toward the outside of the roller mop, thereby reducing the friction between the scraper and the roller mop when the roller mop rotates, thereby avoiding the problem of the roller being stuck or the roller mop being damaged by the scraper.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0044] See also Figures 1 to 6As shown, according to an embodiment of the present application, a cleaning device is provided, which may be a multifunctional cleaning station. The cleaning device includes a cleaning component 1, a moving component 2, and a base station 3. The cleaning component 1 may be a floor brush, and the cleaning component includes a main body 10, a cleaning component 20, and a scraper component 30.

[0045] Among them, the cleaning component 20 is arranged at the bottom of the main body 10; the scraper component 30, the scraper component 30 is installed on the main body 10 and is located on the outside of the cleaning component 20, the scraper component 30 includes a scraper 31, the scraper 31 has an arc segment 311, the arc segment 311 is against the cleaning component 20, and the extension direction of the arc segment 311 near the end of the cleaning component 20 deviates from the cleaning component 20.

[0046] Specifically, the cleaning component includes a roller 21 and a roller mop 22, and the roller mop 22 is sleeved on the roller 21. The existing scraper 31 is usually a straight scraper, which is pressed against the roller mop 22, and the friction between the straight scraper and the roller mop 22 is large, which can easily cause the roller 21 to get stuck or the roller mop 22 to wear. In this embodiment, the end of the scraper 31 close to the cleaning component 20 is an arc segment 311, and the extension direction of the end of the arc segment 311 close to the cleaning component 20 deviates from the cleaning component 20. Compared with the straight scraper in the prior art, the direction of the force applied by the arc segment 311 to the roller mop 22 is more biased toward the outside of the roller mop 22, so that the friction between the scraper 31 and the roller mop 22 can be reduced when the roller mop 22 rotates, thereby avoiding the problem of the roller 21 getting stuck or the roller mop 22 being damaged by the scraper 31.

[0047] It should be noted that “the extension direction of the end of the arc segment 311 close to the cleaning component 20 deviates from the cleaning component 20” means that the end of the arc segment 311 close to the cleaning component 20 is not as shown in the attached figure. Figure 7 And attached Figure 8 The method shown in the figure directly abuts against the roller mop 22, but adopts the attached Figure 5 In the manner shown, the arc surface outside the arc segment 311 abuts against the roller mop 22 .

[0048] The cleaning component 20 is rotatably arranged at the bottom of the main body 10. The scraper component 30 is mounted on the main body 10 and is located outside the cleaning component 20. The scraper component 30 includes a scraper 31. A scraper tooth 3111 is arranged on one side of the scraper 31 close to the cleaning component 20. The scraper tooth 3111 abuts against the cleaning component 20. The scraper tooth 3111 is arranged at one end of the arc segment 311 close to the cleaning component 20.

[0049] Specifically, when the cleaning device is started, the cleaning component 20 starts to rotate, the cleaning component 20 cleans the stains on the ground, and the scraper 31 scrapes the sewage and stains on the cleaning component 20. In this embodiment, since the scraper 31 is provided with scraping teeth 3111 on one side of the cleaning component 20, the scraping teeth 3111 can increase the contact area between the scraper 31 and the cleaning component 20. Therefore, when hair or lint is entangled on the cleaning component 20, the scraping teeth 3111 can scrape the hair and lint away, thereby avoiding excessive hair and lint on the cleaning component 20, which ultimately affects the cleaning effect of the cleaning assembly 1.

[0050] Furthermore, the protruding direction of the scraper teeth 3111 is tangent to the outer surface of the cleaning component 20 .

[0051] Specifically, the arc segment 311 is used to scrape off water stains on the roller mop 22, while the scraping teeth 3111 are mainly used to scrape off hair or lint on the roller mop 22. When the protruding direction of the scraping teeth 3111 is not tangent to the outer surface of the cleaning component 20, for example, when the protruding direction of the scraping teeth 3111 is perpendicular to the surface of the cleaning component 20, the scraper 31 will not be able to completely scrape off the water stains on the roller mop 22 due to the large gaps on the scraping teeth 3111 when scraping the roller mop 22. When the protruding direction of the scraping teeth 3111 is tangent to the outer surface of the roller mop 22, this means that when the arc segment 311 scrapes off the roller mop 22, the water stains on the roller mop 22 will not be completely scraped off due to the influence of the scraping teeth 3111. In addition, since hair and lint are usually entangled on the outer surface of the roller mop 22, when the protruding direction of the scraping teeth 3111 is tangent to the surface of the roller mop, the hair and lint on the roller mop 22 can be scraped off better.

[0052] Further, the scraping teeth 3111 include a plurality of scraping teeth 3111 along a first direction (such as the attached Figure 2 The rollers 21 are arranged in sequence in the Y direction, the rollers 21 can rotate around their own axial direction, and the axial direction of the rollers 21 is consistent with the first direction.

[0053] Specifically, the drum 21 is driven by a driving assembly (not shown in the figure) to rotate, and the drum mop 22 rotates under the drive of the drum 21, so that the drum mop 22 can clean the stains on the ground. The multiple scraping teeth 3111 are arranged in sequence along the first direction, and the first direction is consistent with the axis direction of the drum 21, that is, the multiple scraping teeth 3111 can scrape the outer side of the drum mop 22 in the axis direction at the same time, thereby avoiding uneven installation positions of the multiple scraping teeth 3111, resulting in some dirt on the drum mop 22 not being scraped off.

[0054] Further, the scraping teeth 3111 are arranged in a second direction (such as the attached Figure 4The shape of the projection surface in the X direction (in the middle X direction) includes at least one of a triangle and a trapezoid.

[0055] Specifically, as attached Fig. 9 To Attachment Fig.16 As shown, the shape of the projection surface of the scraping teeth 3111 in the second direction includes an isosceles triangle, an oblique triangle, an isosceles trapezoid, an oblique trapezoid, etc. In addition, along the direction in which the scraping teeth 3111 approach the roller mop 22, the area of ​​the projection surface of the scraping teeth 3111 in the second direction gradually decreases, so that the end of the scraping teeth 3111 close to the roller mop 22 is smaller or the end of the gap between two adjacent scraping teeth 3111 is smaller, and the end of the gap and the end of the scraping teeth 3111 can scrape off the hair and lint wrapped around the roller mop 22.

[0056] Considering that when the scraping teeth 3111 contact the roller mop 22, if the contact surface between the scraping teeth 3111 and the roller mop 22 is too sharp, the friction between the sharp part and the roller mop 22 may cause damage to the roller mop 22. Therefore, in this embodiment, the tooth tip of the scraping teeth 3111 and / or the tooth root of the scraping teeth 3111 are provided with arc angles.

[0057] It should be noted that the tooth tip of the scraper tooth 3111 refers to the end of the scraper tooth 3111 close to the roller mop 22, and the tooth root of the scraper tooth 3111 refers to the corner of the gap between two adjacent scraper teeth 3111. "The tooth tip of the scraper tooth 3111 and / or the tooth root of the scraper tooth 3111 are provided with an arc angle" refers to one of the three situations: the tooth tip of the scraper tooth 3111 is provided with an arc angle, the tooth root of the scraper tooth 3111 is provided with an arc angle, and the tooth tip of the scraper tooth 3111 and the tooth root of the scraper tooth 3111 are both provided with an arc angle. In this embodiment, the tooth tip of the scraper tooth 3111 and the tooth root of the scraper tooth 3111 are both provided with an arc angle, and the arc angle is formed by grinding at the tooth tip and the tooth root.

[0058] Furthermore, the thickness A of the scraping teeth 3111 satisfies the relationship: 1mm≤A≤2mm. When A satisfies the above relationship, the thickness of the scraping teeth 3111 will not be too thick, nor will the thickness of the scraping teeth 3111 be too thin, thereby avoiding the scraping teeth 3111 from reducing the cleaning effect of hair and lint and avoiding the problem that the scraping teeth 3111 are easily damaged after long-term use of the cleaning component 1. When A is less than 1mm, the thickness of the scraping teeth 3111 is too thin, and the scraping teeth 3111 are easily damaged after long-term wear between the scraping teeth 3111 and the roller mop 22. When A is greater than 2mm, the thickness of the scraping teeth 3111 is too thick, which increases the manufacturing cost of the scraper 31 on the one hand, and reduces the scraping effect of fine objects such as hair and lint on the other hand. The value range of A can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm and 2mm.

[0059] Optionally, the length B of the scraping teeth 3111 satisfies the relationship: 1.2 mm ≤ B ≤ 1.6 mm.

[0060] Specifically, since the scraping teeth 3111 need to rub against the roller mop 22 for a long time, if the length B of the scraping teeth 3111 is too short, that is, B is less than 1.2 mm, after the scraping teeth 3111 are worn too much, the scraping effect of the scraping teeth 3111 on the roller mop 22 is easily invalid. If the length B of the scraping teeth 3111 is too long, that is, B is greater than 1.6 mm, on the one hand, it may cause the scraping teeth 3111 to apply too much pressure on the roller mop 22, and eventually cause the scraping teeth 3111 to scratch the roller mop 22 or cause the roller 21 to be stuck by the scraping teeth 3111. On the other hand, if the scraping teeth 3111 are too long, it is easy to make the gap between two adjacent scraping teeth 3111 too long. The too long gap leads to a certain distance between the roller mop 22 and the end of the gap, thereby reducing the scraping effect of the scraper 31 on the stains on the roller mop 22. The value of B can be 1.2mm, 1.25mm, 1.3mm, 1.35mm, 1.4mm, 1.45mm, 1.5mm, 1.55mm and 1.6mm.

[0061] Optionally, the tooth width C of the scraper teeth 3111 satisfies the relationship: 2mm≤C≤5mm.

[0062] Specifically, the tooth width of the scraping teeth 3111 is related to the number of scraping teeth 3111. When the number of scraping teeth 3111 is large, the tooth width of the scraping teeth 3111 should be narrower, and when the number of scraping teeth 3111 is small, the tooth width of the scraping teeth 3111 should be wider. In addition, if the tooth width of the scraping teeth 3111 is narrower, for example, C is less than 2mm, the scraping teeth 3111 have a better cleaning effect on the hair and fluff on the roller mop 22, but the number of scraping teeth 3111 that need to be processed on the scraper 31 is large, resulting in processing difficulties and excessive manufacturing costs of the scraper 31. When the tooth width C of the scraping teeth 3111 is too wide, for example, when C is greater than 5mm, the overly wide scraping teeth 3111 are difficult to effectively clean fine dirt such as hair and fluff on the roller mop 22. The value of C can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm and 5mm.

[0063] Furthermore, the scraping teeth 3111 abut against the roller mop 22 , and a hard layer 211 is provided on one side of the roller 21 close to the roller mop 22 .

[0064] Specifically, the hard layer 211 on the roller 21 is a hard rubber layer, and the provision of the hard rubber layer can improve the structural strength of the roller 21 and reduce the plasticity of the roller 21. This means that when the roller mop 22 contacts the ground, it is not easily subjected to the pressure exerted by the ground, thereby causing the roller 21 to deform.

[0065] Furthermore, the distance D between the scraper teeth 3111 and the hard layer 211 satisfies the relationship: 2 mm ≤ D ≤ 3 mm.

[0066] Specifically, the roller mop 22 is arranged between the scraping teeth 3111 and the hard layer 211. When the roller mop 22 absorbs water, the thickness of the roller mop 22 will become wider. The roller mop 22 usually has bristles, and the length of the bristles is usually set to about 7 mm. Hair usually adheres to the bristles. When the scraping teeth 3111 are pressed against the roller mop 22, the bristles are pressed against the outer periphery of the roller mop 22 after passing through the scraper 31, and under the action of the scraping teeth 3111, the hair and fluff on the bristles are scraped off. In addition, if the pressure applied by the scraping teeth 3111 to the roller mop 22 is large, the roller mop 22 may be unable to rotate or the bristles on the roller mop 22 may be damaged. When the pressure applied by the scraping teeth 3111 to the roller mop 22 is small, it is difficult for the scraping teeth 3111 to scrape off the dirt on the roller mop 22.

[0067] In this embodiment, the distance D between the scraping teeth 3111 and the hard layer 211 can be used to adjust the pressure applied by the scraping teeth 3111 on the roller mop 22, that is, when D is smaller, the pressure applied by the scraping teeth 3111 on the roller mop 22 is greater. On the contrary, when D is larger, the pressure applied by the scraping teeth 3111 on the roller mop 22 is smaller. D satisfies the relationship: 2mm≤D≤3mm. On the one hand, it can avoid that the scraper 31 applies too much pressure on the roller mop 22, resulting in the bristles on the roller mop 22 being scratched. On the other hand, when D satisfies the above relationship, it can avoid that the scraper 31 applies too little pressure on the roller mop 22, thereby reducing the cleaning effect of the scraper 31 on the stains on the roller mop 22.

[0068] As attached Figure 3 , Attachment Figure 5 And attached Fig. 9 As shown, the scraper component 30 also includes a water spray plate group 32, which is arranged on the top of the scraper 31. A flow channel is opened in the water spray plate group 32. A plurality of water spray holes 3213 are arranged on one side of the water spray plate group 32 close to the cleaning component 20. The plurality of water spray holes 3213 are arranged along the extension direction of the cleaning component 20, and the water spray holes 3213 are connected to the flow channel.

[0069] Specifically, the cleaning device further includes a clean water tank, one end of the flow passage is connected to the clean water tank, so that the water in the clean water tank can flow through the multiple water spray holes 3213 to the roller mop 22, so as to cooperate with the scraper 31 to scrape the stains on the roller mop 22. In this embodiment, the water spray plate group 32 includes a front water spray plate 321 and a rear water spray plate 322, multiple water spray holes 3213 are provided on the front water spray plate 321, and the rear water spray plate 322 is buckled on the front water spray plate 321. A side of the rear water spray plate 322 close to the front water spray plate 321 is provided with multiple flow channels 3221, and the multiple flow channels 3221 are connected with the multiple water spray holes 3213. A side of the rear water spray plate 322 away from the front water spray plate 321 is provided with a water inlet 3222, and the water inlet 3222 is connected with the multiple flow channels 3221. The water inlet 3222 , the plurality of flow channels 3221 and the plurality of water spray holes 3213 form a flow passage.

[0070] In order to prevent the dirt from being splashed onto the water spray plate group 32 and accumulated on the water spray plate group 32 when the scraper 31 scrapes the dirt on the roller mop 22 under the action of external force, the scraper component 30 in this embodiment further includes a dustproof pad 33, which is arranged between the scraper 31 and the water spray plate group 32, so as to prevent the dirt from being splashed onto the water spray plate group 32.

[0071] Furthermore, the cleaning assembly 1 further comprises an elastic component 50 , which is disposed between the scraper component 30 and the main body 10 . The scraper component 30 has a tendency to move closer to the cleaning component 20 under the elastic force of the elastic component 50 .

[0072] Specifically, the elastic component 50 includes a spring 51, which is disposed between the rear water spray plate 322 and the main body 10. The spring 51 applies elastic force to the rear water spray plate 322, so that the rear water spray plate 322 drives the scraper 31 to move close to the cleaning component 20. When the surface of the roller mop 22 or the scraper 31 is worn to a certain extent, the scraper 31 can be pressed against the roller mop 22 again under the elastic force of the spring 51, thereby preventing the scraper 31 from failing to scrape away stains on the roller mop 22 after the scraper 31 or the roller mop 22 is worn to a certain extent.

[0073] In some embodiments, the spring 51 includes a plurality of springs 51 , which are spaced apart along the first direction so that the elastic force exerted on the scraper member 30 at each location in the first direction is equal.

[0074] Furthermore, the cleaning assembly 1 further includes a rotating component 70 , and the scraper component 30 is rotatably connected to the main body 10 via the rotating component 70 .

[0075] Specifically, the scraper component 30 rotates around the rotating component 70 so that the scraper 31 has the ability to automatically adjust the pressure applied by the scraper 31 to the roller mop 22, that is, when the pressure applied by the scraper 31 to the roller mop 22 is too large, the roller mop 22 applies a reverse force to the scraper 31, so that the scraper component 30 deflects at a certain angle around the rotating component 70, thereby reducing the pressure applied by the scraper 31 to the roller mop 22.

[0076] Furthermore, the rotating component 70 includes at least two pins 71, at least one pin 71 passes through the main body 10 and is connected to one end of the scraper component 30 in the first direction, and at least one pin 71 passes through the main body 10 and is connected to the other end of the scraper component 30 in the first direction, and the scraper component 30 can rotate around the pin 71.

[0077] In a specific embodiment, the pins 71 include two, and the two pins 71 pass through the main body 10 and are connected to the two sides of the front water spray plate 321, so that the front water spray plate 321 can rotate around the two pins 71, so that the scraper 31 can automatically adjust the pressure applied by the scraper 31 to the roller mop 22 to a certain extent.

[0078] Furthermore, the main body 10 further includes a sealing baffle 40, which is disposed at the bottom of the scraper 31. Specifically, the sealing baffle 40 is sealingly disposed between the main body 10 and the scraper 31 to prevent dirt scraped by the scraper 31 from entering the main body 10 of the cleaning component 1 from the bottom of the scraper 31, thereby contaminating the cleaning component 1.

[0079] Furthermore, a stop protruding section 41 is provided on the sealing baffle 40 . The stop protruding section 41 extends in a direction close to the scraper 31 . The stop protruding section 41 has a first position abutting against the scraper 31 and a second position separated from the scraper 31 .

[0080] In this embodiment, the stop protruding section 41 can be used to cooperate with the rotation of the scraper 31, that is, when the scraper 31 rotates, the stop protruding section 41 abuts against the scraper 31 and is located at the first position. When the scraper 31 does not rotate, the stop protruding section 41 is separated from the scraper 31 and is located at the second position. Specifically, the scraper 31 rotates under the action of the roller mop 22, so that the stop protruding section 41 abuts against the scraper 31, so that a closed space is formed between the scraper 31 and the sealing baffle 40, preventing dirt from entering between the scraper 31 and the sealing baffle 40. In this embodiment, the stop protruding section 41 is a soft rubber block.

[0081] Furthermore, the top of the sealing baffle 40 has an anti-wear portion 42, which is arranged along the height direction of the cleaning component 1 (such as the attached Figure 4 In the middle Z direction), a first gap 61 is provided between the anti-wear portion 42 and the scraper 31 .

[0082] Specifically, when the scraper 31 rotates around the pin 71, the sealing baffle 40 and the scraper 31 may be attached to each other. If the friction between the sealing baffle 40 and the scraper 31 is too large, the sealing baffle 40 and the scraper 31 may be damaged. Therefore, in this embodiment, a wear-resistant portion 42 with a small friction coefficient is provided on the top of the sealing baffle 40, thereby improving the service life of the sealing baffle 40. In addition, in the initial state, there is a first gap 61 between the wear-resistant portion 42 and the scraper 31. The wear-resistant portion 42 of this embodiment can be a metal pad.

[0083] Further, in the initial state, the width E of the first gap 61 satisfies the relationship: 0.3 mm ≤ E ≤ 0.6 mm.

[0084] Specifically, the "initial state" refers to a state in which the scraper 31 does not rotate around the rotating member 70 and the upper surface of the scraper 31 is parallel to the upper surface of the sealing baffle 40. That is, when the scraper 31 rotates, the first gap 61 may not exist between the anti-wear portion 42 and the scraper 31. The first gap 61 has a certain limit on the rotation angle of the scraper member 30 around the rotating member 70, that is, in the initial state, the larger the width E of the first gap 61, the larger the angle at which the scraper member 30 can rotate. When E is less than 0.3 mm, the angle at which the scraper 31 can rotate is small, which may cause the scraper 31 to still apply too much pressure to the roller mop 22 after the rotation, and eventually the roller mop 22 is scraped by the scraping teeth 3111 or the roller 21 is stuck by the pressure applied by the scraper 31. When E is greater than 0.6 mm, the angle at which the scraper 31 can rotate is too large, and after the scraper 31 rotates, the external force applied by the scraper 31 to the roller mop 22 may be small, which eventually reduces the cleaning effect of the scraper 31 on the roller mop 22. In the initial state, the value of E can be 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm and 0.6mm.

[0085] In addition, a mounting cavity 11 is provided on the main body 10 , and the scraper component 30 is disposed in the mounting cavity 11 . Along the height direction of the cleaning component 1 , a second gap 62 is provided between the mounting cavity 11 and the scraper component 30 .

[0086] In this embodiment, the scraper component 30 can have a certain rotation angle in the installation cavity 11 . Similarly, the second gap 62 is the same as the first gap 61 , and is used to limit the rotation angle of the scraper component 30 .

[0087] Further, in the initial state, the width F of the second gap 62 satisfies the relationship: 0.15 mm≤F≤0.3 mm.

[0088] Specifically, in the initial state, the width F of the second gap 62 is too large, and the angle at which the scraper member 30 can rotate in the installation cavity 11 is larger. When F satisfies the above relationship, after the scraper 31 rotates, the pressure applied by the scraper 31 to the roller mop 22 will not be too large, thereby causing damage to the roller mop 22 or the roller 21 being unable to rotate. At the same time, the pressure applied by the scraper 31 to the roller mop 22 will not be too small, resulting in difficulty for the scraper 31 to scrape off dirt on the roller mop 22. The value of F can be 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, 0.2mm, 0.21mm, 0.22mm, 0.23mm, 0.24mm, 0.25mm, 0.26mm, 0.27mm, 0.28mm, 0.29mm and 0.3mm.

[0089] In one embodiment, the installation cavity 11 has a first side wall 111 and a second side wall 112 opposite to each other in the height direction of the cleaning component 1. Along the height direction of the cleaning component 1, a first gap 61 is provided between the bottom of the scraper component 30 and the first side wall 111, and a second gap 62 is provided between the top of the scraper component 30 and the second side wall 112. In the initial state, the width E of the first gap 61 satisfies the relationship: 0.3mm≤E≤0.6mm, and the width F of the second gap 62 satisfies the relationship: 0.15mm≤F≤0.3mm.

[0090] Specifically, the first side wall 111 and the second side wall 112 of the installation cavity 11 respectively limit the rotation of the scraper component 30 with the first gap 61 and the second gap 62 between the scraper component 30, thereby preventing the scraper component 30 from rotating too much in the installation cavity 11, resulting in a small pressure applied by the scraper 31 to the cleaning component 20, making it difficult for the scraper 31 to scrape the stains on the cleaning component 20. At the same time, the small rotation angle of the scraper component 30 in the installation cavity 11 is avoided, so that after the scraper component 30 rotates, the pressure applied by the scraper 31 to the cleaning component 20 is still large, which eventually causes the cleaning component 20 to be scratched or stuck. In this embodiment, the sealing baffle 40 forms the first side wall 111 of the installation cavity 11.

[0091] In addition, a third limiting section 1121 is provided on one side of the installation cavity 11 close to the cleaning component 20 . The third limiting section 1121 extends in a direction close to the scraper 31 . Along the second direction, a third gap 63 is provided between the third limiting section 1121 and the scraper component 30 .

[0092] Specifically, in this embodiment, the third limiting section 1121 is provided on the second side wall 112, and the third limiting section 1121 extends in a direction close to the first side wall 111. The third limiting section 1121 is used to limit the distance that the scraper 31 moves in a direction close to the roller mop 22, that is, when the spring 51 exerts a large elastic force on the scraper component 30, the scraper 31 will exert a large pressure on the roller mop 22 through force transmission, thereby causing the roller mop 22 to be scratched by the scraping teeth 3111 or the roller mop 22 to be stuck and unable to rotate. The existence of the third limiting section 1121 enables the scraper component 30 to press against the third limiting section 1121 when the spring 51 exerts a large elastic force on the scraper component 30, and the third limiting section 1121 exerts a reverse force on the scraper component 30, thereby reducing the pressure exerted by the scraper 31 on the roller mop 22. In addition, the side of the installation cavity 11 facing away from the cleaning component 20 includes a third side wall 113 , and the elastic component 50 is disposed between the third side wall 113 and the scraper component 30 .

[0093] Further, in the initial state, the width G of the third gap 63 satisfies the relationship: 0.4 mm ≤ G ≤ 0.8 mm.

[0094] Specifically, in the initial state, the value of G can be 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.65mm, 0.7mm, 0.75mm and 0.8mm. In the initial state, when G is greater than 0.8mm, the compression amount of the spring 51 needs to be set larger, which is easy to cause fatigue of the spring 51 and reduce the service life of the spring 51. In the initial state, when G is less than 0.4mm, if the scraper 31 or the roller mop 22 is worn to a certain extent, the scraper 31 may not be able to press against the roller mop 22 under the action of the third limit section 1121, and finally the dirt on the roller mop 22 cannot be scraped off.

[0095] Furthermore, along the second direction, a fourth gap 64 is defined between the side wall of the installation cavity 11 facing away from the cleaning member 20 and the scraper member 30 .

[0096] Specifically, a limiting protrusion 34 is provided on one side of the scraper component 30 close to the third side wall 113, and along the second direction, a fourth gap 64 is provided between the limiting protrusion 34, the third side wall 113, and the scraper component 30. The fourth gap 64 is used to limit the distance that the limiting protrusion 34 moves toward the third side wall 113, that is, when the elastic force applied by the spring 51 to the scraper component 30 is less than the force applied by the roller mop 22 to the scraper component 30, the scraper component 30 will move in a direction away from the cleaning component 20, and when the limiting protrusion 34 abuts against the third side wall 113, the scraper component 30 stops moving, thereby preventing the scraper 31 from being separated from the roller mop 22 to a certain extent.

[0097] Further, in the initial state, the width H of the fourth gap 64 satisfies the relationship 0.4mm≤H≤0.8mm. Specifically, in the initial state, when H is greater than 0.8mm, the scraper component 30 may move toward the side wall of the mounting cavity 11 away from the cleaning component 20, and finally the scraper 31 does not abut against the roller mop 22. When H is less than 0.4mm, if the scraper component 30 rotates around the rotating component 70, the scraper component 30 may interfere with the side wall of the mounting cavity 11 away from the cleaning component 20. The value of H can be 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.65mm, 0.7mm, 0.75mm and 0.8mm.

[0098] As attached Figure 5 and attached Figure 6 As shown, the scraper 31 also has a straight section 312, which is arranged at the end of the arc section 311 away from the cleaning component 20. The tangent line passing through the endpoint of the end of the arc section 311 away from the straight section 312 and tangent to the arc section 311 is the first tangent line, and the angle M between the first tangent line and the straight section 312 satisfies the relationship: 80°≤M≤87°.

[0099] In this embodiment, when M is less than 80° and M is greater than 87°, the end of the arc segment 311 close to the cleaning component 20 may directly abut against the outer surface of the cleaning component 20, which may eventually cause the cleaning component 20 to be stuck or the roller mop 22 on the cleaning component 20 to be scratched. The value of M can be 80°, 81°, 82°, 83°, 84°, 85°, 86° and 87°.

[0100] Furthermore, the arc segment 311 has a first arc surface that abuts against the cleaning component 20 and a second arc surface that deviates from the first arc surface. The radius of curvature R1 of the first arc surface satisfies the relationship: 3.5mm≤R1≤4mm. When R1 satisfies the above relationship, the first arc surface can have a certain tangent portion with the outer surface of the cleaning component 20, thereby preventing the end of the arc segment 311 from abutting against the outer surface of the cleaning component 20, which eventually causes the cleaning component 20 to get stuck or the roller mop 22 to be scratched. When R1 is less than 3.5mm, the end portion of the arc segment 311 may abut against the outer surface of the cleaning component 20. When R1 is greater than 4mm, the arc segment 311 is too large, which increases the manufacturing cost on the one hand and may cause the arc segment 311 to interfere with other components on the other hand. The value of R1 can be 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm and 4mm.

[0101] Optionally, the curvature radius R2 of the second arc-shaped surface satisfies the relationship: 2.3 mm≤R2≤2.5 mm.

[0102] Specifically, after the curvature radius R1 of the first arc surface is determined, if the curvature radius R2 of the second arc surface is too large, for example, R2 is greater than 2.5 mm, the arc segment 311 is too thick, which may cause interference between the arc segment 311 and other components; and if the curvature radius R2 of the second arc segment 311 is too small, for example, R2 is less than 2.3 mm, the arc segment 311 is too thin, and the strength of the arc segment 311 is too low, making the scraper 31 easily damaged by external force.

[0103] Furthermore, the distance I between the end of the arc segment 311 away from the straight segment 312 and the upper surface of the straight segment 312 satisfies the relationship: 5.2mm≤I≤5.6mm. When I satisfies the above relationship, the extension length of the arc segment 311 is moderate. On the one hand, it can prevent the arc segment 311 from being too short, causing the end of the arc segment 311 to abut against the outer surface of the roller mop 22; on the other hand, the moderate extension length of the arc segment 311 can prevent the arc segment 311 from being too long and eventually interfering with other parts of the cleaning device. When I<5.2mm, the length of the arc segment 311 is short, which may cause the end of the arc segment 311 to abut against the outer surface of the roller mop 22, eventually causing the roller mop 22 to be scratched or the roller 21 to be stuck. When I is greater than 5.6mm, the extension length of the arc segment 311 is too long, which may cause interference between the arc segment 311 and other parts. Meanwhile, the extended length of the arc segment 311 is too long, which increases the manufacturing cost of the scraper 31. The value of I can be 5.2 mm, 5.3 mm, 5.4 mm, 5.5 mm and 5.6 mm.

[0104] As attached Figure 3 And attached Figure 5 As shown, a first limiting section 3211 is provided on one side of the bottom of the water spray plate group 32 close to the cleaning component 20 . The first limiting section 3211 abuts against the straight section 312 and is located outside the end of the dustproof pad 33 close to the cleaning component 20 .

[0105] Specifically, the first limiting section 3211 is disposed at the bottom of the front water spraying plate 321, and the first limiting section 3211 can guide the water sprayed from the water spraying hole 3213 to a certain extent. The water flows to the straight section 312 under the stop of the first limiting section 3211, and finally flows to the roller mop 22 through the arc section 311. In addition, the first limiting section 3211 also has a certain protective effect on the dustproof pad 33, and the first limiting section 3211 can prevent the water sprayed from the water spraying hole 3213 from flowing to the dustproof pad 33 to a certain extent.

[0106] To prevent dirt from entering the installation cavity 11 from between the dustproof pad 33 and the water spray plate assembly 32, in this embodiment, a limiting groove 331 is provided on the top of the dustproof pad 33 away from the cleaning component 20. A second limiting section 3212 adapted to the limiting groove 331 is provided on the bottom of the water spray plate assembly 32 away from the cleaning component 20, and the second limiting section 3212 is inserted into the limiting groove 331.

[0107] Specifically, the scraper 31, the dustproof pad 33 and the water spray plate group 32 are connected by screws, and the second limiting section 3212 is arranged on the side of the front water spray plate 321 close to the rear water spray plate 322, and the second limiting section 3212 is inserted into the limiting groove 331, so that a sealed space is formed between the dustproof pad 33 and the end of the water spray plate group 32 close to the third side wall 113, thereby preventing the water spray plate group 32 and the dustproof pad 33 from entering the installation cavity 11.

[0108] Furthermore, a hooking section 332 is provided at one end of the dustproof pad 33 facing away from the cleaning component 20 . The hooking section 332 extends toward the direction approaching the sealing baffle 40 and stops on the sealing baffle 40 .

[0109] In this embodiment, the setting of the hooking section 332 can improve the sealing effect between the sealing baffle 40 and the scraper 31, and prevent the dirt from entering the installation cavity 11 from between the scraper 31 and the sealing baffle 40. Specifically, when the scraper component 30 rotates, the first limiting section 3211 abuts against the scraper 31, which can have a certain sealing effect between the scraper 31 and the sealing baffle 40. When the first limiting section 3211 cannot abut against the scraper 31, external dirt may enter the installation cavity 11 from between the sealing baffle 40 and the scraper 31. In this embodiment, the hooking section 332 always abuts against the sealing baffle 40, thereby preventing the dirt from entering the installation cavity 11. In this embodiment, the hooking section 332 is set in a U shape. When the scraper component 30 rotates, the hooking section 332 will also rotate, but because the hooking section 332 is set in a U shape, the hooking section 332 can always abut against the sealing baffle 40.

[0110] 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.

[0111] 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.
