Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the present utility model provides a water tank sealing structure 10 of a floor washing machine, comprising: the water tank body 100, the water tank upper cover 200 and the sealing assembly 300. The sealing assembly 300 is provided between the connection positions of the tank body 100 and the tank upper cover 200, fills the gap at the connection position of the tank body 100 and the tank upper cover 200, and seals the tank.

Referring to fig. 1 and 5, a receiving groove 110 is formed at an upper end of the tank body 100, an annular pressing bar 210 is disposed on the tank upper cover 200, the annular pressing bar 210 is matched with the receiving groove 110, when the tank upper cover 200 is covered on the tank body 100, the annular pressing bar 210 is embedded into the receiving groove 110, a sealing cavity is defined by the annular pressing bar 210 and an inner wall of the receiving groove 110, and the sealing assembly 300 is accommodated in the sealing cavity.

Referring to fig. 4 and 5, the sealing assembly 300 includes a soft rubber ring 310 and a curable filler layer 320, the soft rubber ring 310 is accommodated in the sealing cavity, the curable filler layer 320 is filled in a gap between the soft rubber ring 310 and the sealing cavity, and the curable filler layer 320 is latex-shaped and has fluidity before curing. The curable filler layer 320 may be made of a room temperature curable adhesive such as white latex.

Referring to fig. 4 and 5, when the upper tank cover 200 is covered on the tank body 100, the soft rubber ring 310 is placed in the accommodating groove 110, the curable filler layer 320 is filled in the accommodating groove 110, the upper tank cover 200 is covered on the tank body 100 before the curable filler layer 320 is cured, and the annular pressing strip 210 can squeeze the curable filler layer 320 to the vacant part in the sealing cavity due to the flowability of the uncured curable filler layer 320, so that the curable filler layer 320 can compensate the gap between the sealing cavity and the soft rubber ring 310 due to the injection defect, thereby solving the air tightness problem caused by the fact that the annular pressing strip 210 cannot normally press the soft rubber ring 310 due to the injection defect. In this state, the annular bead 210 cannot contact the soft rubber ring 310, and the curable filler layer 320 fills in the gap between the annular bead 210 and the soft rubber ring 310 to provide a seal.

Further, the curable filler layer 320 has tackiness to adhere the tank body 100 to the tank top cover 200.

Referring to fig. 4 and 6, the soft rubber ring 310 is provided with an extension portion 311 and a plurality of overflow portions 312, the extension portion 311 is located on a side surface of the soft rubber ring 310, which is close to the contact of the annular pressing bar 210, and the width of the extension portion 311 is smaller than the width of the sealing cavity. When the extension part 311 and the soft rubber ring 310 are positioned in the accommodating groove 110, an interval is formed between the extension part 311 and the inner wall of the accommodating groove 110, so that a space is provided for the soft rubber ring 310 to deform under pressure, and the soft rubber ring 310 has better contraction capability in the pressing direction of the annular pressing bar 210. Therefore, the problem of air tightness caused by the fact that the upper cover 200 of the water tank and the main body 100 of the water tank cannot be completely closed due to the overlong annular pressing strip 210 (or the too shallow depth of the accommodating groove 110) caused by the injection defect is solved. In this state, the annular bead 210 presses the extension 311 and makes it concave such as the soft rubber ring 310 itself, and the curable filler at this site is extruded into the overflow 312 and the site where the annular bead 210 and the receiving groove 110 are normal in size.

Referring to fig. 5, preferably, a groove 314 is disposed at the junction between the soft rubber ring 310 and the extension 311.

Referring to fig. 4 and 5, the overflow portions 312 are equally spaced along the extending track of the soft rubber ring 310. The overflow portion 312 is configured to accommodate the excess curable filler layer 320, the uncured curable filler layer 320 has fluidity, and the excess curable filler layer 320 is extruded into the overflow portion 312 by the annular molding 210; when the annular bead 210 is prevented from being inserted into the receiving groove 110, the excessive curable filler layer 320 is extruded, and after curing, a pimple is formed at the junction of the tank body 100 and the tank cover 200, or is adhered to the peripheral part of the tank. The overflow 312 is circular, rectangular in cross-section or otherwise shaped depending on the amount of curable filler layer 320 that is filled during assembly. Preferably, the width of the overflow portion 312 is smaller than the width of the extension portion 311, and the overflow portion 312 extends from the top of the soft rubber ring 310 to the bottom of the soft rubber ring 310. The cross-sectional width of the overflow 312 is 1/3 of the width of the soft rubber ring 310.

Referring to fig. 7, in an embodiment, a plurality of overflow grooves 313 are formed on the outer wall of the soft rubber ring 310, the overflow grooves 313 on the outer wall of the soft rubber ring 310 make the soft rubber ring 310 easier to bend, and avoid the bending portion of the soft rubber ring 310 from swelling, and when the annular pressing strip 210 is embedded into the accommodating groove 110, the excessive curable filler is extruded into the overflow grooves 313 to form the curable filler layer 320, so as to further reduce the overflow amount of the curable filler.

Referring to fig. 1, in one embodiment, a space avoiding groove 120 is formed on the water tank body 100, and the space avoiding groove 120 is communicated with the accommodating groove 110.

In summary, the soft rubber ring 310 is used as a main sealing component to seal the joint of the water tank body 100 and the water tank upper cover 200, and the gap between the soft rubber ring 310 and the joint of the water tank body 100 and the water tank upper cover 200 is filled with the curable filler layer 320, so that the defect generated in the injection molding process is overcome, and the sealing performance of the water tank sealing structure 10 of the floor washing machine is improved.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model.
