[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] In the drawings, for clarity, the shapes and dimensions may be enlarged, and the same reference numerals will be used throughout the figures to indicate the same or similar components.

[0046] In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are defined with respect to the configurations shown in the respective drawings. In particular, "height" corresponds to the dimension from the top to the bottom, "width" corresponds to the dimension from the left to the right, and "depth" corresponds to the dimension from the front to the back. They are relative concepts and thus may change accordingly depending on their different positions and usage states. Therefore, these or other orientations should not be construed as restrictive terms.

[0047] Terms related to attachment, connection, etc. (e.g., "connect" and "attach") refer to the relationship in which these structures are directly or indirectly fixed or attached to each other through an intermediate structure, as well as a movable or rigid attachment or relationship, unless otherwise explicitly stated.

[0048] According to an embodiment of the present invention in combination with Figures 1 to 3 as shown, it can be seen that the water-absorbing brush head 1 includes:

[0049] A water storage tank 12, which is hollow inside to form a receiving space for storing sewage;

[0050] A brush head housing 11, which is open at the top to form a water storage tank mounting groove 111 for mounting and removing the water storage tank 12; and

[0051] A water absorption structure 17, which is provided directly below the brush head housing 11, and the water absorption structure includes:

[0052] A bottom plate 171, which is provided directly below the brush head housing 11 and is detachably connected to the bottom of the brush head housing 11; and

[0053] A water absorption channel 172, which is formed between the brush head housing 11 and the bottom plate 171;

[0054] Among them, a sealing port 115 leading to the water absorption channel 172 is opened on the bottom wall of the water storage tank installation groove 111, and the water storage tank 12 is removably installed in the water storage tank installation groove 111. When the water storage tank 12 is not installed in the water storage tank installation groove 111 or removed from the water storage tank installation groove 111, the water absorption channel 172 cannot perform the water absorption operation due to the vacuum break of the sealing port 115; when the water storage tank 12 is installed in the water storage tank installation groove 111, the bottom of the water storage tank 12 covers the sealing port 115, so that the water absorption channel 172 is no longer broken vacuum, so that the water absorption operation can proceed smoothly, to prevent the problem of sewage pollution of other components caused by the lack of collection of sewage during the water absorption operation due to the non-installation of the water storage tank 12. In addition, since the water storage tank 12 is arranged in the water absorption brush head, the water tank can be generally kept in a horizontal posture during the operation of the water absorption brush by the user, effectively preventing the sewage in the water tank from pouring out.

[0055] Refer to Figure 3 , the water storage tank 12 is open at its top to form a sewage discharge port 121 for discharging sewage, and a water tank cover 122 is rotatably connected to the top of the water storage tank 12 to open and close the sewage discharge port 121.

[0056] Furthermore, the water absorption brush head 1 further includes a pipeline assembly 16, and the pipeline assembly 16 includes:

[0057] A flexible water suction pipe 161, one end of which leads to the bottom of the brush head housing 11 and is communicated with the rear end of the water absorption channel 172; and

[0058] A drain pipe 163 and a gas guide pipe 162 leading to the internal accommodation space of the water storage tank 12,

[0059] wherein, the drain pipe 163 and the gas guide pipe 162 are bent upward near the end where they are connected to the water storage tank 12, so that the drain port 1631 of the drain pipe 163 and the gas guide port 1621 of the gas guide pipe 162 are both arranged upward.

[0060] Furthermore, a drain guide inlet 1212 and a gas guide inlet 1211 respectively communicated with the drain pipe 163 and the gas guide pipe 162 are opened in the water storage tank 12, wherein the drain guide inlet 1212 and the gas guide inlet 1211 are both arranged near the edge of the sewage discharge port 121. Adopting this layout method can ensure that the drain guide inlet 1212 and the gas guide inlet 1211 can always be above the sewage liquid level in the water storage tank 12, thereby preventing problems such as sewage backflow into subsequent components through the drain pipe 163 and the gas guide pipe 162, causing component pollution or even damage.

[0061] Refer to againFigure 3 The water storage tank 12 is further provided with a water level detection chamber 124, which is connected to the water storage tank 12 at its top. Wherein, a water level detection unit for detecting the water level in the water storage tank 12 is provided in the water level detection chamber 124.

[0062] Refer to Figure 2 and 3 , it further includes:

[0063] A water suction grid assembly 13, which is arranged between the brush head housing 11 and the bottom plate 171 and is located at the front end of the brush head housing 11; and

[0064] A water suction pipe channel 176, which is arranged between the brush head housing 11 and the bottom plate 171 and is located at the rear end of the brush head housing 11;

[0065] Wherein, the water suction channel 172 is arranged between the water suction grid assembly 13 and the water suction pipe channel 176, and the front and rear ends of the water suction channel 172 are respectively aligned with the water suction grid assembly 13 and the water suction pipe channel 176. Thus, the sewage-air mixed fluid sucked by the water suction grid assembly 13 can be introduced into the water suction pipe 176. In a preferred embodiment, auxiliary rollers 178 are rotatably connected to the left and right sides of the water suction pipe channel 176.

[0066] Refer to Figure 3 , a water suction grid installation groove 116 that is recessed upward is formed at the front end of the brush head housing 11, and the top of the water suction grid assembly 13 is received in the water suction grid installation groove 116; at the front end of the bottom plate 171, a water suction grid installation leading edge 175 and a water suction grid installation trailing edge 174 are arranged opposite to each other in the front-rear direction, and the water suction grid installation leading edge 175 and the water suction grid installation trailing edge 174 are spaced apart to form a water suction grid receiving groove therebetween, and the bottom of the water suction grid assembly 13 is inserted into the water suction grid receiving groove.

[0067] Combined with Figure 3 and Figure 4 's illustration, it can be seen that the water suction grid assembly 13 includes a guiding unit 131 and a water suction unit 132 that are arranged in sequence from top to bottom, and the guiding unit 131 is inserted into the water suction unit 132.

[0068] Furthermore, the guiding unit 131 includes:

[0069] A guiding installation plate 1311 extending in the horizontal direction; and

[0070] An upper installation plate 1312 and a lower installation plate 1313 respectively fixed to the upper and lower surfaces of the guiding installation plate 1311, and the upper installation plate 1312 and the lower installation plate 1313 extend substantially in the vertical direction;

[0071] Among them, the upper mounting plate 1312 is located at the rear end of the guiding mounting plate 1311, the lower mounting plate 1313 is located at the front end of the guiding mounting plate 1311, and a plurality of parallel and spaced guiding vertical plates 1315 are fixedly connected between the lower surface of the guiding mounting plate 1311 and the lower mounting plate 1313. Flow guiding holes leading to the water absorption channel are formed between every two of the guiding vertical plates 1315. By dividing the water absorption port into a number of guiding holes with smaller diameters, larger dirt can be blocked outside the water absorption port.

[0072] Furthermore, a plurality of parallel and spaced reinforcing ribs 1314 are fixedly connected between the upper surface of the guiding mounting plate 1311 and the upper mounting plate 1312, and the reinforcing ribs 1314 and the upper mounting plate 1312 are inserted into the water absorption grid mounting groove 116. The reinforcing ribs 1314 can enhance the matching strength between the guiding unit 131 and the water absorption grid mounting groove 116 and improve the installation stability of the guiding unit 131 in the water absorption grid mounting groove 116.

[0073] Refer again to Figures 3 to 5 , it can be seen that the water absorption unit 132 includes:

[0074] A water absorption mounting plate 1321 extending in the horizontal direction, in which a flow guiding groove 1323 penetrating its upper and lower surfaces is provided; and

[0075] Two water absorption guiding plates 1322 respectively arranged at the front and rear edges of the flow guiding groove 1323, which are fixedly connected to the lower surface of the water absorption mounting plate 1321;

[0076] Among them, the guiding vertical plate 1315 is inserted between the two water absorption guiding plates 1322 through the flow guiding groove 1323; the water absorption unit 132 is inserted into the water absorption grid accommodation groove through the two water absorption guiding plates 1322. Thus, the sewage-air mixed fluid sucked from the bottom gap of the water absorption guiding plate 1322 can be split and guided by the guiding vertical plate 1315, and the flow direction of the fluid can be changed from vertically upward to horizontally towards the water absorption channel 172 ( Figure 5 the direction of arrow S in).

[0077] Refer again to Figure 5 , the transverse dimension of the water absorption channel 172 gradually decreases in the front-to-back direction. The water absorption channel 172 with this structure can make the sucked sewage-air mixed fluid gradually converge as the fluid travels, which is convenient for the downstream water suction pipe 161 to centrally suck.

[0078] Further, a filtering channel 173 facing the water suction pipe channel 176 is communicatively provided at the rear end of the water absorption channel 172, and a filtering unit 114 is provided in the filtering channel 173. By providing a filtering unit in the filtering channel to filter medium-sized dirt, it fully ensures that the subsequent pipeline is unobstructed. Refer to Figure 1 , a fluid guiding pipe 113 is docked between the filtering channel 173 and the water suction pipe 161.

[0079] Refer to Figure 2 and Figure 5 , the water absorption channel 172 has a symmetrical structure about the center line O of the bottom plate 171. A triangular pressure increasing block 177 is provided at the center of the water absorption channel 172. A pressure increasing channel 172a is formed between the pressure increasing block 177 and the side wall of the water absorption channel 172. The setting of the pressure increasing block 177 can prevent the flow rate of the sewage mixed fluid from slowing down due to the increase in the cross-sectional area of the flow channel at the center of the channel 172, which helps to improve the suction force of the water absorption brush head.

[0080] Refer to again Figure 2 and Figure 4 , the water absorption guiding plate 1322 continues to extend downward until it protrudes from the bottom surface of the water absorption grid accommodating groove. A retaining terminal 1322 fixed to the outer side surface of the water absorption guiding plate 1322 is formed at the part where the water absorption guiding plate 1322 protrudes from the bottom surface of the water absorption grid accommodating groove. Thus, when the water absorption brush contacts the area to be decontaminated, the water absorption guiding plate 1322 can prevent the water absorption guiding plate 1322 from slipping off due to the upward pressure through the cooperation of the retaining terminal 1322 and the water absorption grid accommodating groove.

[0081] Working principle:

[0082] Refer to Figure 5 , the sewage-air mixed fluid is sucked from the bottom gap of the water absorption guiding plate 1322, and after being divided and guided by the guiding vertical plate 1315, it enters the water absorption channel 172 along the arrow S direction. In the water absorption channel 172, it converges to the center of the water absorption channel 172 along the arrow M and arrow N directions and is introduced into the filtering channel 173. After being filtered by the filtering unit 114 in the filtering channel 173, the sewage-air mixed fluid is finally sucked by the water suction pipe 161. After being separated by the water-air separation unit connected to the subsequent pipeline, the air is discharged and the sewage is collected and processed.

[0083] The equipment quantity and treatment scale described here are used to simplify the description of the present invention. The application, modification and variation of the present invention are obvious to those skilled in the art.

[0084] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples described herein.
