Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.

As shown in fig. 1, the present embodiment provides a cleaning apparatus, which may be any one of a floor scrubber, a sweeping robot, and a washing and mopping integrated machine. The cleaning apparatus includes a spray mechanism 100 and a cleaning member 300 for cleaning a floor. In operation, the spray mechanism 100 sprays cleaning liquid onto the surface of the cleaning members 300, thereby maintaining the cleaning members 300 wet so as to enhance the cleaning effect.

Referring to fig. 1 to 3, the spraying mechanism 100 includes a plurality of nozzles 1, the plurality of nozzles 1 being spaced apart along a first direction, the nozzles 1 being used to spray cleaning liquid onto the cleaning member 300, thereby spraying the cleaning liquid onto a plurality of places on the surface of the cleaning member 300, where the first direction is perpendicular to a moving direction of the cleaning member 300 when in operation. The spray mechanism 100 also includes a liquid supply assembly in communication with the nozzle 1 for providing cleaning liquid to the nozzle 1.

However, the spraying effect of the spraying mechanism 100 in this way is to form dots, and the dots are spaced apart from each other, so that the cleaning solution is unevenly distributed, and the cleaning solution may not cover the entire cleaning member 300, so that a relatively large amount of cleaning solution on the cleaning member 300 easily causes liquid residues on the ground, and a relatively small amount of cleaning solution on the cleaning member 300 reduces the cleaning effect, thereby affecting the cleaning effect of the cleaning member 300.

As shown in fig. 2 to 4, in order to solve the above-mentioned problems, the nozzle 1 in the present embodiment may be used to spray the cleaning solution to the cleaning member 300, or may directly spray the cleaning solution to the floor, so as to meet the structural requirements of different users or cleaning devices, and facilitate the expansion of the application range of the spraying mechanism 100. Meanwhile, the nozzles 1 comprise the divergent flow passages 11, the sizes from the first inlets 111 of the divergent flow passages 11 to the first outlets 112 of the divergent flow passages 11 are gradually increased along the first direction, the cleaning liquid flows along the directions from the first inlets 111 to the first outlets 112, and the spraying areas of the two adjacent nozzles 1 are at least overlapped at the boundary, so that the problem that the water quantity of the cleaning piece 300 is unevenly distributed after the cleaning liquid is sprayed by the existing nozzles 1 is solved, the cleaning liquid is more evenly distributed on the surface of the cleaning piece 300, the whole cleaning cloth can be covered, water stains remained on the ground are avoided, and the cleaning effect of the cleaning piece 300 is improved.

The cleaning apparatus is advantageous in improving cleaning effect and improving user satisfaction by providing the above-described spray mechanism 100.

Specifically, when the spray mechanism 100 sprays the cleaning liquid toward the floor, the spray mechanism 100 is positioned in front of the cleaning member 300, and the cleaning apparatus moves forward to enable the cleaning member 300 to drag onto the cleaning liquid, thereby cleaning the floor. When the spraying mechanism 100 sprays the cleaning liquid directly to the cleaning member 300, the cleaning member 300 can be kept wet, and thus mopping can be performed.

In addition, along the first direction, the size of the first outlet 112 is 2-10 times that of the first inlet 111, and a user can select to use the first outlets 112 with different sizes according to the width of the cleaning member 300, so that the range of spraying cleaning liquid by the first outlets 112 is enlarged, and the situation that the cleaning member 300 cannot be sprayed in place due to overlarge spacing of the nozzles 1 is avoided.

Further, the size of the first inlet 111 along the first direction is 0.5 mm-1.5 mm, which is favorable for increasing the pressure of the first inlet 111 to the cleaning liquid, forming mist of the cleaning liquid sprayed from the first outlet 112, further improving the spraying uniformity, and ensuring that the cleaning liquids sprayed from adjacent nozzles 1 are at least partially overlapped.

As shown in fig. 4, optionally, the size of the divergent runner 11 along the first direction is larger than the size of the divergent runner 11 along the second direction, and the second direction is perpendicular to the first direction, so that the divergent runner 11 has a flat structure, which is beneficial to increasing the pressure of the cleaning solution dispersed along the first direction, thereby ensuring the uniformity of spraying.

As an alternative, the size of the divergent flow path 11 in the second direction is 0.4mm to 1mm, so that the pressure of the first inlet 111 to the cleaning liquid is increased, which is beneficial to forming the cleaning liquid sprayed from the first outlet 112 into a mist, and further improving the spray uniformity.

With continued reference to fig. 4, the spray mechanism 100 further includes a first base 2, and the nozzle 1 is disposed on the first base 2 so as to communicate with the liquid supply assembly. Further, in order to ensure that the liquid output of each nozzle 1 is uniform, at least a part of the liquid dividing channels 21 are provided on the first base 2, and the liquid dividing channels 21 uniformly divide the cleaning liquid obtained from the liquid supply assembly to each nozzle 1.

In addition, spray mechanism 100 still includes second base 4, second base 4 sets up with first base 2 relatively, divide liquid passageway 21 can set up on first base 2, also can set up on second base 4, of course, also can set up simultaneously on first base 2 and second base 4, after first base 2 and second base 4 are connected relatively, form confined minute liquid passageway 21, the third entry and the feed liquid subassembly intercommunication of minute liquid passageway 21, this structure is favorable to reducing minute liquid passageway processing degree of difficulty, reduce spray mechanism 100's manufacturing cost.

As shown in fig. 4, the nozzle 1 further includes a diversion flow passage 12, and the first outlet 112 of the divergent flow passage 11 has the same size along the first direction as the outline of the nozzle 1, i.e. the cleaning liquid has penetrated the nozzle 1 when being sprayed along the first outlet 112. The flow guiding flow channel 12 extends along the flowing direction of the cleaning liquid, and the flow guiding flow channel 12 extends from the direction of the first outlet 112 to the direction far away from the first inlet 111 to the end face of the nozzle 1, at this time, the flow guiding flow channel 12 has pressure along the second direction on the cleaning liquid, so as to increase the pressure of the cleaning liquid sprayed along the first direction, ensure that the cleaning liquid can be uniformly distributed within the opening angle range of the second outlet 132, ensure that the cleaning liquid between adjacent nozzles 1 is at least partially overlapped, and simultaneously be beneficial to increasing the atomization degree of the cleaning liquid.

Optionally, the nozzle 1 further includes a converging flow channel 13, two ends of the converging flow channel 13 are respectively communicated with the liquid separating channel 21 and the diverging flow channel 11, the size from the second inlet 131 of the converging flow channel 13 to the second outlet 132 of the converging flow channel 13 is gradually reduced along the first direction, and the cleaning liquid flows along the direction from the second inlet 131 to the second outlet 132, so that the pressure of the cleaning liquid flowing out from the second outlet 132 is increased, which is beneficial to increasing the atomization effect of the sprayed cleaning liquid and increasing the pressure of the cleaning liquid sprayed from the first outlet 112.

Further, the nozzle 1 further comprises a transition flow channel 14, and two ends of the transition flow channel 14 are respectively communicated with the second outlet 132 and the first inlet 111, so that the flow channel length of the cleaning liquid in the nozzle 1 is prolonged, the pressure of the sprayed cleaning liquid is increased, and the cleaning liquid between adjacent nozzles 1 is at least partially overlapped. Specifically, the dimension of the second outlet 132 along the first direction is not smaller than the dimension of the first inlet 111 along the first direction, so as to avoid the pressure of the cleaning liquid flowing out of the second outlet 132 from the transition flow channel 14.

Optionally, the local protrusion first base 2 of nozzle 1 sets up to make the structure of nozzle 1 not receive the thickness restriction of first base 2, be favorable to improving nozzle 1 structural design's flexibility, be favorable to prolonging conflux runner 13, transition runner 14 and divergent runner 11 along the length of cleaning solution flow direction, thereby guarantee the atomization effect when cleaning solution sprays, and be favorable to guaranteeing the spraying width of cleaning solution along first direction, make the cleaning solution between the adjacent nozzle 1 at least partial coincidence.

As an alternative, when the spraying mechanism 100 sprays the cleaning solution to the ground, the spraying mechanism 100 further comprises a cover plate 3, a plurality of mounting holes are formed in the cover plate 3, a part of the nozzle 1 is located in the mounting holes, the cover plate 3 is connected with the housing 200 of the cleaning device, the spraying mechanism 100 is fixed on the housing 200 by using the cover plate 3, and the nozzle 1 is prevented from being blocked due to the fact that the nozzle 1 is exposed outside, so that the nozzle 1 is protected.

It will be understood by those skilled in the art that the present utility model is not limited to the foregoing embodiments, but rather, the foregoing embodiments and description illustrate the principles of the utility model, and that various changes and modifications may be effected therein without departing from the spirit and scope of the utility model as defined by the appended claims and their equivalents.
