[0053] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] In the drawings, the shapes and dimensions may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like components.

[0055] In the following description, words such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are defined relative to the structure shown in the drawings. In particular, "height" is equivalent to the dimension from top to bottom, "width" is equivalent to the dimension from left to right, and "depth" is equivalent to the dimension from front to back. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other directions should not be interpreted as restrictive terms.

[0056] Terms referring to attachment, coupling, and the like (eg, "connected" and "attached") refer to structures being fixed or attached to one another, directly or indirectly, through intermediate structures, as well as movable or rigid attachments or relationships, unless expressly stated otherwise.

[0057] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown in FIG. 1 , it can be seen that the water-absorbing brush 1 with a water-gas separation structure includes:

[0058] a water-absorbing brush head 11; and

[0059] The water vapor separation structure is provided at the rear end of the water absorbing brush head 11, and comprises a pitch connection pipe 14, a water collecting cup 15 and a water vapor separation assembly 18, which are arranged in sequence from front to back;

[0060] Among them, the pitch connecting tube 14 is hollow inside and open at both ends. The pitch connecting tube 14 is rotatably connected to the rear end of the water-absorbing brush head 11 so that the pitch connecting tube 14 can make reciprocating pitch rotations relative to the water-absorbing brush head 11 in a vertical plane; the water collecting cup 15 is hollow inside and open at its top to form an opening. The water collecting cup 15 is rotatably connected to the other end of the pitch connecting tube 14 at its bottom so that the water collecting cup 15 can make reciprocating translational motions relative to the pitch connecting tube 14 in a horizontal plane; the water vapor separation component 18 is detachably connected to the top of the water collecting cup 15 to seal the opening; a pipeline component 16 is provided inside the pitch connecting tube 14, one end of the pipeline component 16 is connected to the water-absorbing brush head 11, and the other end is connected to the water collecting cup 15. The above structure allows the user to quickly and easily adjust the relative posture between the water-absorbing brush head 11 and the surface to be cleaned by adjusting the pitch angle of the pitch connecting tube 14 and the rotation angle between the water collecting cup 15 and the pitch connecting tube 14, thereby improving the efficiency of sucking and removing sewage.

[0061] Reference Figure 13 The water-absorbing brush head 11 is open at its top to form a water tank installation groove 111, in which a water tank 12 is removably installed. The water tank 12 is hollow inside to form a storage space for storing sewage.

[0062] Furthermore, a water absorbing structure 17 is provided directly below the water absorbing brush head 11, and the water absorbing structure includes:

[0063] a bottom plate 171 , which is disposed directly below the water absorbing brush head 11 and is detachably connected to the bottom of the water absorbing brush head 11 ; and

[0064] A water absorption channel 172 formed between the water absorption brush head 11 and the bottom plate 171;

[0065] The bottom wall of the water tank mounting slot 111 is provided with a sealing opening 115 leading to the water suction channel 172. When the water tank 12 is not installed in the water tank mounting slot 111 or is removed from the water tank mounting slot 111, the water suction channel 172 cannot perform water suction operations due to the vacuum caused by the sealing opening 115. When the water tank 12 is installed in the water tank mounting slot 111, the bottom of the water tank 12 covers the sealing opening 115, so that the vacuum in the water suction channel 172 no longer breaks, allowing the water suction operation to proceed smoothly. This prevents the problem of sewage contaminating other components due to the lack of water tank 12 during the water suction operation. In addition, because the water tank 12 is arranged in the water suction brush head, the water tank can remain roughly horizontal during the user's operation, effectively preventing sewage from spilling out of the water tank.

[0066] Further, refer to Figure 3 The water tank 12 is opened at its top to form a sewage outlet 121 for discharging sewage, and a water tank cover 122 is rotatably connected to the top of the water tank 12 to open and close the sewage outlet 121.

[0067] Reference Figure 3 and Figure 4 , wherein the pipeline assembly 16 is shown in more detail. The pipeline assembly 16 includes:

[0068] A water suction pipe 161 having a turbulent structure, with both ends thereof connected to the water suction channel 172 and the water collecting cup 15 respectively; and

[0069] A drainage pipe 163 and an air guide pipe 162 are led out from the bottom wall of the water collecting cup 15 , and the other ends of the drainage pipe 163 and the air guide pipe 162 are connected to the water storage tank 12 ;

[0070] The air guide tube 162 protrudes from the bottom wall of the water collecting cup 15 and extends upward along the axial direction of the water collecting cup 15 .

[0071] Reference Figure 6 and Figure 7 The water collection cup 15 is provided with an inlet pipe 152 extending axially upward from its bottom. The suction pipe 161 is connected to the bottom of the inlet pipe 152. The outer wall of the inlet pipe 152 is spaced apart from the inner wall of the water collection cup 15 to form a water collection space therebetween. The water collection cup 15 is connected to the outside world through the bottom of the inlet pipe 152. The inlet pipe 152 is connected to the water vapor separation assembly 18 at its top. Furthermore, the water collection cup 15 includes a cup body 151 with a hollow interior and an open top. The inlet pipe 152 extends axially upward from the center of the bottom wall of the cup body 151. This allows the sewage-air mixture introduced into the water collection cup 15 through the inlet pipe 152 to be directed into the water vapor separation assembly 18 for water vapor separation. The separated air is ultimately drawn out from the top of the cup body 151, and the separated sewage is collected by the cup body 151.

[0072] Refer again Figure 4The water tank 12 is open at its top to form a sewage discharge port 121 for discharging sewage, and the top of the water tank 12 is rotatably connected to a water tank cover 122 to open and close the sewage discharge port 121; a drainage inlet 1212 and an air inlet 1211 are respectively connected to the drainage pipe 163 and the air guide pipe 162, wherein the drainage inlet 1212 and the air guide pipe 1211 are both arranged near the edge of the sewage discharge port 121; the drainage pipe 163 and the air guide pipe 162 are bent upward near the end portion connected to the water tank 12, so that the drainage port 1631 of the drainage pipe 163 and the air guide port 1621 of the air guide pipe 162 are both arranged upward. This layout ensures that the drainage inlet 1212 and the air inlet 1211 are always located above the sewage level in the water tank 12, thereby preventing sewage from flowing back into subsequent components through the drainage pipe 163 and the air pipe 162, causing contamination or even damage to the components.

[0073] Furthermore, the water tank 12 is also provided with a water level detection chamber 124, which is connected to the water tank 12 at its top, wherein the water level detection chamber 124 is provided with a water level detection unit for detecting the water level in the water tank 12.

[0074] Reference Figures 13 to 15 The water absorbing brush head 11 is further provided with a water absorbing grid assembly 13, which is arranged between the water absorbing brush head 11 and the bottom plate 171 and located at the front end of the water absorbing brush head 11. A water absorbing pipe channel 176 is formed between the water absorbing brush head 11 and the bottom plate 171 and located at the rear end of the water absorbing brush head 11;

[0075] The water suction channel 172 is disposed between the water suction grid assembly 13 and the water suction pipe channel 176, with the front and rear ends of the water suction channel 172 aligned with the water suction grid assembly 13 and the water suction pipe channel 176, respectively. This allows the sewage-air mixture drawn through the water suction grid assembly 13 to be directed 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.

[0076] Refer again Figure 13 The front end of the water-absorbing brush head 11 is provided with an upwardly concave water-absorbing grid mounting groove 116, and the top of the water-absorbing grid assembly 13 is accommodated in the water-absorbing grid mounting groove 116; the front end of the bottom plate 171 is provided with a water-absorbing grid mounting front edge 175 and a water-absorbing grid mounting rear edge 174 arranged opposite to each other in the front and rear directions, and the water-absorbing grid mounting front edge 175 and the water-absorbing grid mounting rear edge 174 are spaced apart to form a water-absorbing grid accommodating groove located therebetween, and the bottom of the water-absorbing grid assembly 13 is inserted into the water-absorbing grid accommodating groove.

[0077] Combine Figure 13 and Figure 14 As shown in the figure, it can be seen that the water absorption grid assembly 13 includes a guide unit 131 and a water absorption unit 132 arranged in sequence from top to bottom, and the guide unit 131 is inserted into the water absorption unit 132.

[0078] Furthermore, the guiding unit 131 includes:

[0079] A guide mounting plate 1311 extending in a horizontal direction; and

[0080] An upper mounting plate 1312 and a lower mounting plate 1313 are respectively fixed to the upper and lower surfaces of the guide mounting plate 1311, and the upper mounting plate 1312 and the lower mounting plate 1313 extend substantially in the vertical direction;

[0081] The upper mounting plate 1312 is located at the rear end of the guide mounting plate 1311, and the lower mounting plate 1313 is located at the front end of the guide mounting plate 1311. Multiple parallel and spaced guide vertical plates 1315 are fixedly connected between the lower surface of the guide mounting plate 1311 and the lower mounting plate 1313. Diversion holes leading to the water suction channel are formed between each pair of guide vertical plates 1315. By dividing the water suction port into several smaller diversion holes, larger dirt can be blocked from entering the water suction port.

[0082] Furthermore, a plurality of parallel and spaced reinforcing ribs 1314 are fixedly connected between the upper surface of the guide mounting plate 1311 and the upper mounting plate 1312. The reinforcing ribs 1314 and the upper mounting plate 1312 are inserted into the water absorption grille mounting groove 116. The reinforcing ribs 1314 can strengthen the fit between the guide unit 131 and the water absorption grille mounting groove 116, thereby improving the installation stability of the guide unit 131 in the water absorption grille mounting groove 116.

[0083] Refer again Figures 13 to 15 , it can be seen that the water absorption unit 132 includes:

[0084] A water absorbing mounting plate 1321 extending in the horizontal direction, wherein guide grooves 1323 are formed through the upper and lower surfaces thereof; and

[0085] Two water absorption guide plates 1322 are respectively provided at the front and rear edges of the guide groove 1323 and fixed to the lower surface of the water absorption mounting plate 1321;

[0086] The guide plate 1315 is inserted between the two water suction guide plates 1322 through the guide groove 1323; the water suction unit 132 is inserted into the water suction grid receiving groove through the two water suction guide plates 1322. As a result, the sewage-air mixed fluid sucked from the gap at the bottom of the water suction guide plate 1322 is divided and guided by the guide plate 1315, and the flow direction of the fluid is changed from vertical upward to horizontal toward the water suction channel 172 ( Figure 5 direction of arrow S in the figure).

[0087] Refer again Figure 5 The transverse dimension of the water suction channel 172 gradually decreases from the front to the back. The water suction channel 172 with such a structure can make the sucked sewage-air mixed fluid gradually converge as the fluid moves, making it easier for the downstream water suction pipe 161 to absorb it in a concentrated manner.

[0088] Furthermore, the rear end of the water suction channel 172 is connected to the water suction pipe channel 176 and provided with a filter channel 173, wherein the filter channel 173 is provided with a filter unit 114. By providing the filter unit in the filter channel to filter medium-sized dirt, the subsequent pipeline is fully guaranteed to be unobstructed. Figure 1 A fluid guide pipe 113 is connected between the filter channel 173 and the water suction pipe 161 .

[0089] Reference Figure 2 and Figure 5 The water suction channel 172 has a symmetrical structure about the center line O of the bottom plate 171. A triangular boosting block 177 is provided at the center of the water suction channel 172. A boosting channel 172a is formed between the boosting block 177 and the side wall of the water suction channel 172. The setting of the boosting block 177 can prevent the flow rate of the sewage mixed fluid from slowing down due to the increase in the flow channel cross-sectional area at the center of the channel 172, which helps to improve the suction force of the water suction brush head.

[0090] Refer again Figure 2 and Figure 4 The water suction guide plate 1322 continues to extend downward until it protrudes from the bottom surface of the water suction grid receiving groove. The water suction guide plate 1322 protruding from the bottom surface of the water suction grid receiving groove is formed with an anti-slip terminal 1322 fixedly connected to the outer surface of the water suction guide plate 1322, so that when the water suction brush contacts the area to be cleaned, the water suction guide plate 1322 can prevent the water suction guide plate 1322 from slipping due to upward pressure through the cooperation of the anti-slip terminal 1322 and the water suction grid receiving groove.

[0091] Refer again Figures 2 to 4At least one lock assembly 19 is provided between the water vapor separation assembly 18 and the water collection cup 15, which is used to lock and unlock the connection state between the water vapor separation assembly 18 and the water collection cup 15. The lock assembly 19 includes:

[0092] A first lock base 191 , which is fixedly disposed on the outer side of the water-gas separation assembly 18 ;

[0093] a second locking base 192 , which is fixedly disposed on the outer side of the water collecting cup 15 and is opposite to the first locking base 191 ;

[0094] a locking member 193 disposed between the first lock base 191 and the second lock base 192 , wherein the locking member 193 is rotatable relative to the first lock base 191 or the second lock base 192 to change between an unlocked state and a locked state; and

[0095] A reset component 194 capable of elastic deformation is provided on the first lock base 191 or the second lock base 192 and acts on the locking member 193, so that the locking member 193 rotates along a locking direction to reset from the unlocked state to the locked state.

[0096] Reference Figure 5 The outer wall of the water collection cup 15 is formed with a guide groove 153 extending along the axis of the water collection cup 15. The locking member 193 is disposed in the guide groove 153. When the locking member is unlocked, the water collection cup 15 and the moisture separation component 18 can be axially separated under the guidance of the guide groove 153. Conversely, to connect the water collection cup 15 and the moisture separation component, the water collection cup 15 and the moisture separation component 18 can be axially brought together under the guidance of the guide groove 153. In one embodiment, two sets of lock assemblies 19 are provided symmetrically about the axis of the water collection cup 15, and correspondingly, two sets of guide grooves 153 are also provided.

[0097] Now refer to Figure 8 , which shows in detail the specific structure of the water-gas separation component 18, the water-gas separation component 18 includes:

[0098] an end cap 181, which is coupled to the top of the water collecting cup 15 to seal the opening;

[0099] The water-gas separation cylinder 183 is hollow inside and has an open bottom to form a docking port;

[0100] a filter cartridge 184 connected to the top of the water-gas separation cartridge 183; and

[0101] an exhaust pipe 182 , which is hollow inside and open at both ends;

[0102] The air extraction pipe 182 is disposed in the end cap 181. Its bottom end is connected to the top end of the filter cartridge 184. The water inlet pipe 152 leads to the interior of the water-gas separation cartridge 183 through the docking port. The top end of the air guide pipe 162 is no lower than the bottom end of the water-gas separation cartridge 183. During sewage extraction, the top end of the air guide pipe 162 is never submerged by sewage collected in the water collection cup 15. This allows the air guide pipe 162 to maintain pressure equilibrium between the water collection cup 15 and the outside atmosphere, preventing leakage and sewage backflow.

[0103] Refer again Figure 8 A drainage pipe 185 is fixedly connected to the interior of the water-gas separation cylinder 183 , and the drainage pipe 185 extends axially downward from the top of the water-gas separation cylinder 183 , and the top of the water inlet pipe 152 is connected to the bottom of the drainage pipe 185 .

[0104] Furthermore, a drainage port 1851 is provided on the side wall of the drainage pipe 185 , so that the air flow can be connected to the water inlet pipe 152 through the drainage port 1851 .

[0105] Furthermore, a plurality of filter holes are provided on the side wall of the filter cartridge 184 , so that dirt such as lint can be blocked out by the filter holes, and as it gradually accumulates, it can slide into the cup body 151 and be finally collected by the cup body 151 .

[0106] Reference Figure 9 and Figure 10 , which shows in detail the detailed structure of the drainage tube 185. Specifically, the drainage tube 185 includes a starting section 185a and an ending section 185c, and a detour section 185b integrally formed between the starting section 185a and the ending section 185c, wherein the curvature radius of the detour section 185b gradually increases in the direction from the starting section 185a to the ending section 185c, and the drainage port 1851 is opened between the starting section 185a and the ending section 185c.

[0107] Refer again Figure 8 and Figure 10 The end of the starting section 185a is integrally formed with a guide section 185d tangent to the starting section 185a, so that the air outlet direction of the drainage port 1851 is consistent with the tangent direction of the end of the detour section 185b. With this structural design, the dirty water / air mixed fluid entering the drainage pipe 185 through the water inlet pipe 152 in the direction of arrow A is forced to follow a spiral path along the detour section 185b and finally be discharged from the drainage port 1851.

[0108] Further, the outer diameter of the water inlet pipe 152 and the outer diameter of the drainage pipe 185 are both smaller than the inner diameter of the water-air separation cylinder 183, the outer wall of the water inlet pipe 152 is spaced apart from the inner wall of the water-air separation cylinder 183 to form a water falling channel therebetween, so that the dirty water / air mixed fluid discharged from the drainage opening 1851 can fall down along the water falling channel from the drainage opening 1851 (the arrow B is shown).

[0109] Referring to Figure 8 , Figure 8 The attitude structure diagram of the water absorption brush in the use state is shown, when the water absorption brush is used, the axis of the water inlet pipe 152 forms an angle γ with the horizontal plane, and the angle γ can generally vary between 5° and 90° according to the use state of the operator, and in the use state as shown in Figure 8 After the dirty water / air mixed fluid discharged from the drainage opening 1851 falls down along the water falling channel from the drainage opening 1851, the dirty water on the lower side of the water inlet pipe 152 then falls into the cup body 151 along the direction of the arrow D, and the dirty water on the upper side of the water inlet pipe 152 then falls into the cup body 151 along the direction of the arrow E, and the air and the flocculent dirt are separated from the water due to the density of the air and the flocculent dirt being much smaller than the density of the water, and the air discharged from the water falling channel is then discharged upward along the direction of the arrow C after being sucked through the air suction pipe 182, and the flocculent dirt is separated from the outside of the outer wall of the filter cylinder 184 after being filtered through the filter cylinder 184, and the filtered air is then discharged along the direction of the arrow F through the air suction pipe 182, and thus the water-air separation process is completed.

[0110] In a preferred embodiment, the inner diameter of the water inlet pipe 152 is consistent with the minimum curvature radius of the detour section 185b.

[0111] Working principle:

[0112] Referring to Figure 15 , the dirty water / air mixed fluid is sucked from the gap at the bottom of the water absorption guide plate 1322 and is guided and separated through the guide vertical plate 1315, and then enters the water absorption channel 172 along the direction of the arrow S, and is gathered to the center of the water absorption channel 172 along the directions of the arrows M and N and is introduced into the filter channel 173, and the dirty water / air mixed fluid is finally sucked by the water suction pipe 161 after being filtered through the filter unit 114 in the filter channel 173;

[0113] Referring to Figure 8 and Figure 10The water suction pipe 161 is connected to the water inlet pipe 152, so that the sucked sewage-air mixed fluid can enter the drainage pipe 185 in the direction of arrow A through the water inlet pipe 152. The sewage-air mixed fluid is then forced to follow a spiral path along the circuitous section 185b and is ultimately discharged from the drainage port 1851. The sewage-air mixed fluid discharged from the drainage port 1851 can fall downward from the drainage port 1851 along the water channel (as shown by arrow B in the figure);

[0114] Reference Figure 8 , Figure 8 The diagram shows the posture structure of the water-absorbing brush in use. When the water-absorbing brush is in use, the axis of the water inlet pipe 152 forms an angle γ with the horizontal plane. Usually, the angle γ can vary between 5° and 90° depending on the operator's use status. Figure 8 In the use state shown, the sewage-air mixed fluid guided out from the drainage port 1851 can fall downward from the drainage port 1851 along the said downflow channel, and then the dirty water on the lower side of the water inlet pipe 152 falls into the cup body 151 along the direction of arrow D, while the dirty water on the upper side of the water inlet pipe 152 falls into the cup body 151 along the direction of arrow E, close to the outer wall of the water inlet pipe 152. Since the density of air and flocculent dirt is much smaller than that of water, after being sucked by the exhaust pipe 182, the air guided out from the said downflow channel is discharged upward along the direction of arrow C, and the flocculent dirt is filtered by the filter cartridge 184. The filtered air passes through the filter cartridge 184 and is discharged through the exhaust pipe 182 in the direction of arrow F, thus completing the water-gas separation process. Subsequently, the sewage collected by the water collecting cup 15 can be discharged into the water storage tank 12 through the drain pipe 163, and the air pressure balance between the water storage tank 12 and the water collecting cup 15 is maintained by the air guide pipe 162. When the water level detection unit in the water collecting cup 15 detects that the internal space of the water storage tank 12 is about to be full, it sends a water tank full signal to the machine body, and the machine body emits a preset warning buzzer to remind the user to stop the machine in time and clean the water storage tank 12.
