[0002] In existing technology, the water spray strip of the floor scrubber achieves uniform water spraying on the brush bristles by evenly setting multiple water spray nozzles. However, the water spraying directly onto the brush bristles cannot guarantee that the entire brush bristles are sprayed with water, resulting in dry strip-shaped areas on the brush bristles corresponding to the gaps between the water spray nozzles, thereby reducing the cleaning ability of the floor scrubber on the ground. III. Utility Model Content

The first surface has a first edge and a second edge, with the first edge being lower than the second edge in the vertical direction and also lower than any of the sprinkler nozzles. The first surface extends from the first edge to the second edge to form a water storage channel.

[0006] A water spray baffle is fixedly installed relative to the water spray strip. The second surface of the water spray baffle extends vertically downward to a third edge, which is lower than any water spray nozzle and higher than the first edge in the vertical direction; the second surface intersects with the first direction; wherein...

[0007] The water sprayer discharges liquid from the water nozzle in the first direction to the water spray baffle. The liquid flows into the water storage channel along the second surface. In response to the liquid inflow, the liquid overflows from the second edge of the water storage channel.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In a first aspect, this application provides a sprinkler strip 101. The first surface of the sprinkler strip 101 is provided with a plurality of sprinkler nozzles 106 along its length, and the sprinkler nozzles 106 spray water along a first direction. The first surface is provided with a first edge 1021 and a second edge 1022. The first edge 1021 is lower than the second edge 1022 in the vertical direction and is also lower than any of the sprinkler nozzles 106. The first surface extends from the first edge 1021 to the second edge 1022 to form a water storage channel 103.

[0047] A water spray baffle 102 is fixedly installed relative to the water spray strip 101. The second surface of the water spray baffle 102 extends vertically downward to a third edge 1023. The third edge 1023 is lower than any water spray nozzle 106 in the vertical direction and higher than the first edge 1021. The second surface intersects with the first direction.

[0048] The water spray strip 101 discharges liquid from the water spray nozzle 106 in the first direction to the water spray baffle 102. The liquid flows into the water storage channel 103 along the second surface. In response to the liquid inflow, the liquid overflows from the water storage channel 103 from the second edge 1022.

[0049] Specifically, refer to Figures 1 to 4 The sprinkler mechanism consists of a sprinkler strip 101 and a sprinkler baffle 102. A sprinkler nozzle 106 is provided on the first surface of the sprinkler strip 101. The nozzle 106 extends downwards along the first surface to the lowest edge of the first surface, i.e., the first edge 1021, and then extends upwards away from the nozzle 106 to a second edge 1022 higher than the first edge 1021, thus forming a water storage channel 103 through the first surface. It is understood that the water storage channel 103 has a groove with the lowest point at the first edge 1021 and the highest point at the second edge 1022. Liquid stored in the water storage channel 103 will overflow from the second edge 1022 when it is full. Furthermore, the sprinkler mechanism is also equipped with a sprinkler baffle 102. The sprinkler baffle 102 is positioned in the first direction in which the liquid is discharged from the sprinkler nozzle 106. It blocks the liquid discharged from the first direction through its second surface, and guides the blocked liquid along the second surface under the action of gravity to the lowest edge of the second surface in the vertical direction, namely the third edge 1023. The third edge 1023 is lower than the sprinkler nozzle 106 in the vertical direction, ensuring that the liquid discharged from the sprinkler nozzle 106 can be accurately guided to the sprinkler baffle 102; the third edge 1023 is higher than the first edge 1021, so that the liquid blocked by the sprinkler baffle 102 can be guided into the water storage channel 103.

[0050] Understandably, the liquid blocked by the sprinkler baffle 102 is guided along the third edge 1023 to the water storage channel 103, i.e. Figure 3 The local magnification part, and Figure 4 As shown by the dotted line, the liquid gradually accumulates upwards from the first edge 1021 until it overflows the second edge 1022. At this point, the water storage channel 103 is full of liquid. The liquid overflows evenly from one side of the second edge 1022 and pours downwards under the action of gravity, forming a uniform liquid plane. This avoids the dry zone caused by direct spraying of the brush bristles from each water nozzle 106, effectively improving the uniformity of liquid spraying and ensuring the cleaning ability of the floor brush.

[0051] In some embodiments, the first edge 1021 and the nozzle 106 of the sprinkler strip 101 of the sprinkler mechanism provided in this application are located on both sides of the third edge 1023 in the horizontal direction.

[0052] Specifically, refer to Figure 4 and Figure 5 The third edge 1023 of the sprinkler baffle 102 is located horizontally between the second edge 1022 and the sprinkler nozzle 106, that is, the second edge 1022 and the sprinkler nozzle 106 are respectively set on both sides of the third edge 1023 in the horizontal direction. The sprinkler baffle 102 guides the blocked liquid through the third edge 1023 to the area between the second edge 1022 and the sprinkler nozzle 106, so that the liquid can be stably guided into the water storage channel 103, ensuring the water storage stability of the water storage channel 103.

[0053] In some embodiments, the first edge 1021, the second edge 1022, and the third edge 1023 are arranged parallel to each other.

[0054] Specifically, refer to Figures 3 to 5 The first edge 1021, the second edge 1022, and the third edge 1023 are arranged parallel to each other. Furthermore, the first edge 1021, the second edge 1022, and the third edge 1023 are arranged in a horizontal direction. The first edge 1021 and the second edge 1022 are arranged parallel to each other, so that the liquid can be evenly distributed in the water storage channel 103. The third edge 1023 is parallel to the first edge 1021 and the second edge 1022, so that the liquid guided by the sprinkler baffle 102 flows evenly into the water storage channel 103.

[0055] In some embodiments, the sprinkler strip 101 has a cavity 105, and the sprinkler strip 101 has at least one water inlet 104 at both ends along its length, and the water inlet 104 is connected to the sprinkler 106 through the cavity 105.

[0056] Specifically, refer to Figure 1The sprinkler strip 101 has at least one water inlet 104, and a cavity 105 is provided inside the sprinkler strip 101, through which liquid enters the cavity 105. In some specific embodiments, the sprinkler strip 101 has two water inlets 104, which are symmetrically arranged at both ends of the sprinkler strip 101 along its length. The cavity 105 can be divided into two first flow channels 1052, two second flow channels 1053, six third flow channels 1054, and six fourth flow channels 1057. One first flow channel 1052 is connected to one second flow channel 1053 through one first node 1051; one second flow channel 1053 is connected to three third flow channels 1057 through three second nodes 1055. The third flow channel 1054 has three second nodes 1055 symmetrically arranged about the first node 1051 along the length of the sprinkler strip 101. One third flow channel 1054 is connected to one fourth flow channel 1057 via two third nodes 1056, and the two third nodes 1056 are symmetrically arranged about the second node 1055 along the length of the sprinkler strip 101. Three sprinkler nozzles 106 are connected to one fourth flow channel 1057, and are symmetrically arranged about the second node 1055 along the length of the sprinkler strip 101. Through the cavity 105 and inlet 104 provided in this application, the sprinkler mechanism can evenly discharge the collected liquid from the sprinkler nozzles 106 through the sprinkler strip 101, thereby ensuring that the liquid discharged from the sprinkler nozzles 106 falls evenly into the water storage channel 103, guaranteeing a uniform spraying effect on the floor brush.

[0057] In some embodiments, the sprinkler strip 101 is provided with two water inlets 104, which are symmetrically arranged at both ends of the sprinkler strip 101 along its length. It is understood that the two water inlets 104 symmetrically arranged along the length of the sprinkler strip 101 can provide relatively symmetrical water channels within the cavity 105, thereby ensuring that the liquid flow velocity in each water channel of the cavity 105 is the same, so as to achieve relatively synchronous liquid discharge from the sprinkler nozzle 106 through the cavity 105. In some specific embodiments, the two water inlets 104 are relatively independent, and the cavities 105 connected to the two water inlets 104 are independent of each other. By providing two sets of independent sprinkler nozzles 106 and cavities 105, interference between liquids in different directions is avoided, ensuring stable liquid flow within the sprinkler strip 101 and the desired liquid spraying effect.

[0058] In some embodiments, the sprinkler strip 101 has a cavity 105 inside; the cavity 105 extends inside the sprinkler strip 101 to a first surface to form a sprinkler nozzle 106.

[0059] Specifically, refer to Figure 2 and Figure 3The cavity 105 inside the sprinkler strip 101 extends to the first surface of the sprinkler strip 101, forming a sprinkler nozzle 106, allowing the liquid entering the sprinkler strip 101 to be evenly discharged from the sprinkler strip 101. In some specific embodiments, the sprinkler nozzle 106 is a funnel-shaped groove or a multi-faceted groove. Taking a quadrangular frustum shape as an example, refer to... Figure 2 and Figure 3 The top surface of the truncated pyramid is directly connected to the cavity 105 and extends along the side of the truncated pyramid to the first plane, so as to form an expanded water nozzle 106 through the side of the truncated pyramid. This ensures the liquid spraying area of ​​the water nozzle 106 and further improves the uniformity of water spraying.

[0060] Secondly, this application provides a floor brush for use in a floor scrubbing machine, comprising:

[0061] At least one sprinkler system as provided in the first aspect of this application, and,

[0062] At least one roller 201 is fixedly arranged relative to the water spray strip 101 of the water spraying mechanism; the roller 201 is arranged in a first direction; the roller 201 rotates in a second direction;

[0063] At least one comb tooth 202 is fixedly connected to the water spray strip 101, and the water spraying mechanism and the comb tooth 202 are sequentially arranged on the outer periphery of the roller 201 along the second direction;

[0064] The housing 203 partially houses the roller 201, the comb teeth 202, and the water spraying mechanism.

[0065] Specifically, refer to Figures 5 to 7 The housing 203 constitutes the main structure of the floor brush, partially accommodating the roller 201, comb teeth 202, and water spraying mechanism. Furthermore, the housing 203 provides direct or indirect physical support for the roller 201, comb teeth 202, and water spraying mechanism, ensuring their mutual fixation. The water spraying mechanism and comb teeth 202 provided in the first aspect of this application can be directly connected to each other, or relatively fixedly connected through the housing 203, and arranged sequentially around the outer periphery of the roller 201 along its rotation direction, i.e., the second direction. The roller 201 is positioned in the first direction to receive liquid overflowing from the water storage channel 103. Further, the roller 201 is provided with bristles to absorb the liquid overflowing from the water storage channel 103. Responding to the relative positional relationship between the comb teeth 202 and the water spraying mechanism, the roller 201, having absorbed the liquid discharged by the water spraying mechanism, can scrape away any entangled or collected debris through the comb teeth 202.

[0066] Furthermore, the roller 201 is connected to the housing 203 via a rolling shaft, causing the roller 201 to roll relative to the housing 203, thus enabling the floor brush to move on the working plane.

[0067] Furthermore, the roller 201 is a multi-layered structure, for example, consisting of a hard rubber tube, an elastic sleeve, and bristles from the inside out. The elastic sleeve is made of a material with elastic deformation capabilities, such as foam. The comb teeth 202 are pressed onto the roller 201, causing elastic deformation at the pressing point, thereby ensuring that the comb teeth 202 and the bristles remain in close contact, thus guaranteeing the cleaning ability of the comb teeth 202.

[0068] Furthermore, the distance between the rolling shaft of the roller 201 and the comb teeth 202 is less than the natural radius of the elastic sleeve in the uncompressed state. The axis of the elastic sleeve is also the rolling shaft, so that even if the bristles are worn during operation, the bristles can still be supported outward by the expansion of the elastic sleeve, so that the bristles always adhere to the comb teeth 202, thereby ensuring the cleaning ability of the comb teeth 202.

[0069] In some embodiments, the second direction is either counterclockwise or clockwise.

[0070] Specifically, refer to Figures 5 to 7 The second direction corresponds to the position design of the suction air duct of the floor scrubber, which is used to suck the debris generated by the floor scrubber during cleaning of the work surface into the debris bin inside the floor scrubber body. Therefore, when the suction air duct is in the opposite direction of the movement direction relative to the contact position between the roller 201 and the ground, the second direction can be set to counterclockwise; when the suction air duct is in the positive direction of the movement direction relative to the contact position between the roller 201 and the ground, the second direction can be set to clockwise.

[0071] In some embodiments, the floor brush further includes a roller 201 baffle, and the roller 201 baffle and the water spray baffle 102 are sequentially disposed on the outer periphery of the roller 201 along the second direction.

[0072] Specifically, refer to Figures 5 to 7 The floor brush is equipped with a roller baffle 201, which, along with the water spray baffle 102, is sequentially arranged on the outer periphery of the roller 201 in the second direction of the roller's rotation. Through the roller baffle 201, the floor brush effectively prevents cleaning debris from splashing during the roller's movement, thus avoiding contamination of the surrounding cleaned area and ensuring the brush's cleaning performance.

[0073] In some embodiments, the water spray baffle 102 and the roller 201 baffle are integrally formed.

[0074] Specifically, refer to Figures 5 to 7The water spray baffle 102 and the roller baffle 201 can be two ends of the same baffle that are integrally formed. That is, the side of the water spray strip 101 that is close to the water spraying mechanism is the water spray baffle 102, which corresponds to one end of the third edge 1023; the other end that is away from the water spraying mechanism is the roller baffle 201. The water spray baffle 102 and the roller baffle 201 are integrally formed and surround the outer periphery of the roller 201, which reduces the assembly difficulty and ensures the stability of the overall structure of the floor brush.

[0075] In some embodiments, the floor brush 200 further includes a roller, which is movably connected to the housing and is positioned behind the housing in the working direction of the floor brush 200. The floor brush 200 is provided with at least one roller, which is used to assist the floor brush 200 in moving stably on the working surface, making it easy for users to drag the floor brush 200 with a floor scrubber and thus control the working direction of the floor brush 200.

[0076] In other embodiments, reference is made to Figure 9The floor brush 200 provided in this application may also include a combination of multiple rollers, a water spraying mechanism, and comb teeth. Taking two rollers, two water spraying mechanisms, and two comb teeth as an example, the floor brush 200 includes a first water spraying strip 2001, a first water spraying baffle 2002, a second water spraying strip 2011, a second water spraying baffle 2012, a first roller 2021, a second roller 2022, a first comb tooth 2031, and a second comb tooth 2032. Further, taking the relative positional relationship and fixing method between the first water spraying mechanism, the first roller 2021, and the first comb tooth 2031 as an example, the first water spraying mechanism is arranged opposite to the first roller 2021, with the first roller 2021 located in a first direction, wherein the first roller 2021 rotates along a second direction. The floor brush 200 also includes first comb teeth 2031, which are sequentially and fixedly connected to the first water spraying strip 2001 of the first water spraying mechanism along a second direction, and are in relative movable contact with the first roller 2021. This allows the first roller 2021 to first contact the liquid sprayed from the water nozzle of the first water spraying mechanism when it rolls on the working surface to perform cleaning work, and then to make movable contact with the first comb teeth 2031 to scrape off any adsorbed or entangled debris on the first roller 2021. The relative positional relationship and connection method between the second roller 2022, the second water spraying mechanism, and the second comb teeth 2032 are the same as those described above for the relative positional relationship and fixing method between the first water spraying mechanism, the first roller 2021, and the first comb teeth 2031. Furthermore, the floor brush 200 housing is connected to the first water spraying strip 2001 of the first water spraying mechanism and the first water spraying strip 2001 of the second water spraying mechanism, respectively. The floor brush 200 housing is connected to the first roller 2021 and the second roller 2022 via a rolling shaft. In some specific embodiments, the first roller 2021 and the second roller 2022 rotate in opposite directions. A gap is provided between the first roller 2021 and the second roller 2022, and the first comb tooth 2031 and the second comb tooth 2032 are disposed between the first roller 2021 and the second roller 2022. A ground pipe 403 is provided on the housing of the floor brush 200 in the vertical direction of the gap. The ground pipe 403 is used to suck the debris scraped by the first comb tooth 2031 and the second comb tooth 2032 into the floor scrubber for collection, thereby cleaning the debris on the ground.

[0077] In some embodiments, refer to Figure 9The floor brush 200 provided in this application also includes a water spray connector 206, which connects the first water spray bar 2001 and the second water spray bar 2011. The water spray connector 206 has a channel for connecting the cavities of the first water spray bar 2001 and the second water spray bar 2011. Specifically, through the water spray connector 206, the water pressure in the first water spray bar 2001 and the second water spray bar 2011 is kept the same, thereby ensuring that the water spray nozzles of the first water spray bar 2001 and the second water spray bar 2011 discharge liquid to the corresponding water storage channel at the same pressure, so as to synchronize the wetness of the first roller 2021 and the second roller 2022, thereby ensuring the consistency of the floor brush 200 in cleaning the working surface.

[0078] Thirdly, this application provides a floor scrubbing machine, comprising:

[0079] For example, the second aspect of the ground brush 200, and

[0080] The machine body 400 is pivotally connected to the floor brush 200, and the pivot axis of the machine body 400 relative to the floor brush 200 is parallel to the working plane of the floor scrubber.

[0081] The handle 300 is arranged parallel to the length of the body 400; the handle 300 is fixedly connected to the body 400.

[0082] The floor scrubber provided in this application, taking the floor brush 200 including two rollers, two water spraying mechanisms, and two comb teeth as an example, refers to... Figure 9 and Figure 10 The floor brush 200 is pivotally connected to the body 400, which can rotate relative to the floor brush 200 to accommodate user operations such as pushing and pulling, ensuring that the floor brush 200 can move in close contact with the work surface. Furthermore, the handle 300 is parallel to the body 400 along its length, allowing the user to control the direction of movement of the body 400, thereby ensuring smooth movement of the floor brush 200 on the work surface.

[0083] In some embodiments, the machine body 400 includes a ground pipe 403, a first end of which is connected to the machine body 400, and a second end of which is fixed relative to the working surface via a ground brush 200.

[0084] Specifically, refer to Figure 10 The first section of the ground pipe 403 is connected to the machine body 400, and the second section is connected to the floor brush 200 and exposed above the working surface. This allows the waste generated when the floor scrubber is working on the working surface to be transferred to the inside of the machine body 400 through the ground pipe 403, thus achieving the cleaning of the floor and the collection of waste.

[0085] In some embodiments, the fuselage 400 includes a wastewater tank 401; the wastewater tank 401 is connected to a first end of a ground pipe 403; specifically, referring to... Figure 10 The machine body 400 contains a wastewater tank 401, which is connected to the first end of a ground pipe 403, allowing the interior of the wastewater tank 401 to communicate with the working surface. In response to ground debris collected by the ground pipe 403, the wastewater tank 401 can store ground debris, such as wastewater.
