[0063] The water tank of the present disclosure, on the one hand, the sealing performance of the welded connection portion 4 is better than that of the sealing ring, so that the sealing performance of the water tank is better and is not easy to leak; on the other hand, since the metal ring 3 is provided, the welded connection portion 4 can be formed by high-frequency induction welding process, using the high-frequency induction heating technology based on electromagnetic induction principle to produce induction heating on the metal ring 3 embedded in the first shell 1 and / or the second shell 2, the first shell 1 and the second shell 2 near the metal ring 3 are heated and melted, and after cooling, a joint is formed, the heating speed is fast, and the first shell 1 and the second shell 2 are less affected, so as to ensure that the outer surface of the first shell 1 and the second shell 2 basically will not produce welding marks, so that the roughness of the outer surface of the first shell 1 and the second shell 2 meets the requirements.

[0064] In the present example embodiment, the material of the first shell 1 is an organic material, for example, the material of the first shell 1 can be PP (Polypropylene), PC (Polycarbonate), ABS (Acrylonitrile Butadiene Styrene plastic, which is a ternary copolymer of three monomers of acrylonitrile (A), butadiene (B) and styrene (S)), nylon and other thermoplastic plastics, and glass fiber-containing plastics, etc. The first shell 1 can be formed by injection molding process.

[0066] The first recess 12 can be used to hold clean water.

[0067] In some exemplary embodiments of this disclosure, the second housing 2 is made of an organic material. For example, the material of the second housing 2 can be thermoplastic plastics such as PP (Polypropylene), PC (Polycarbonate), ABS (Acrylonitrile Butadiene Styrene plastic, a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S), nylon, and plastics containing glass fibers. The second housing 2 can be formed by injection molding.

[0068] Optionally, refer to Figure 1 and Figure 3 , Figure 4 As shown, the second housing 2 has a second recess 24, and a second annular end face 25 is provided on one side of the second housing 2 where the second recess 24 is provided. The second annular end face 25 is provided around the second recess 24. Specifically, the second housing 2 may include a top plate 27 and a plurality of second side plates 28. The plurality of second side plates 28 are all connected to the top plate 27. The plurality of second side plates 28 are connected end to end in sequence to form an annular shape.

The side of the plurality of second side plates 28 facing away from the top plate 27 is connected to form the second annular end face 25, so that the second annular end face 25 is provided around the second recess 24.

[0069] Reference Figure 1 and Figure 4As shown, the second shell 2 and the first shell 1 are mutually covered, that is, the second annular end face 25 and the first annular end face 13 are connected to form a clean water cavity, specifically, the shape of the second annular end face 25 is the same as that of the first annular end face 13, and the size of each part of the second annular end face 25 is also the same as that of each part of the first annular end face 13, so that the second annular end face 25 and the first annular end face 13 can be mutually closed together; so that the first recess 12 and the second recess 24 are used together to accommodate clean water.

[0070] The first shell 1 can be used as a lower shell of a water tank, and the first shell 1 can be mounted on the cleaning part. The first outlet 161 is arranged on the bottom plate 16 of the first shell 1, and the first outlet 161 is arranged opposite to the first recess 12, so that the clean water in the clean water cavity can flow out to the cleaning part through the first outlet 161 to provide water source for the cleaning part.

[0071] The second shell 2 can be used as an upper shell of the water tank. The first inlet 271 is arranged on the top plate 27 of the second shell 2, and the first inlet 271 is arranged opposite to the second recess 24, so that clean water can be injected into the clean water cavity through the first inlet 271.

[0072] Of course, in some other example embodiments of the present disclosure, the first shell 1 as the lower shell of the water tank can be arranged in a flat plate shape, and only the second recess 24 of the second shell 2 is used to accommodate clean water; in this case, the first shell 1 can include the first annular end face 13, which can be a part of the plane of the flat plate-shaped first shell 1. The second shell 2 as the upper shell of the water tank can also be arranged in a flat plate shape, and only the first recess 12 of the first shell 1 is used to accommodate clean water.

[0073] It should be noted that the first shell 1 can be used as a lower shell of a water tank, and the second shell 2 can be used as an upper shell of the water tank, which is determined by the installation and placement of the water tank, and does not constitute a limitation on the present disclosure.

[0074] At least one of the first shell 1 and the second shell 2 is provided with an annular groove 11, for example, referring to Figure 2 and Figure 4 As shown, the annular groove 11 can be arranged on the first shell 1, but not on the second shell 2; the annular groove 11 can be arranged on the second shell 2, but not on the first shell 1; the annular groove 11 can be arranged on the first shell 1 and the second shell 2.

[0075] Referring to Figures 4-8As shown, the metal ring 3 is located in the annular groove 11, and the material of the metal ring 3 can be various metals, for example, the material of the metal ring 3 can be copper, iron, gold, silver, etc. The shape of the metal ring 3 is matched with the shape of the annular groove 11, for example, the annular groove 11 is set as a circular ring, and the metal ring 3 is also set as a circular ring; the annular groove 11 is set as a rectangular ring, and the metal ring 3 is also set as a rectangular ring; the annular groove 11 is set as an irregular ring, and the metal ring 3 is also set as the same irregular ring. So that there is a metal ring 3 at each part of the annular groove 11.

[0076] Referring to Figures 4-8 As shown, the welding connection part 4 is connected between the metal ring 3 and the first shell 1 and the second shell 2, so as to seal and connect the first shell 1 and the second shell 2, and the sealing performance of the welding connection part 4 is better than that of the sealing ring, so that the sealing performance of the water tank is better and is not easy to leak. In addition, due to the arrangement of the metal ring 3, the welding connection part 4 can be formed by a high-frequency induction welding process, and the high-frequency induction heating technology based on electromagnetic induction principle is used to produce induction heating on the metal ring 3 embedded in the first shell 1 and / or the second shell 2. The first shell 1 and the second shell 2 near the metal ring 3 are heated and melted, and after cooling, a joint is formed. The heating speed is fast, and the first shell 1 and the second shell 2 are less affected, so as to ensure that the outer surface of the first shell 1 and the second shell 2 is basically free of welding marks, and the roughness of the outer surface of the first shell 1 and the second shell 2 meets the requirements.

[0077] In the example embodiment, referring to Figure 2 As shown, the annular groove 11 is arranged on the first annular end face 13, that is, the annular groove 11 is arranged on the end face of the shell wall of the first shell 1; and the annular groove 11 is arranged around the first recess 12. The metal ring 3 arranged in the annular groove 11 can be used to abut and seal connect the second annular end face 25 and the first annular end face 13 to form a sealed clean water cavity, so as to avoid leakage of clean water in the sealed clean water cavity, and the outer surface of the first shell 1 and the second shell 2 is basically free of welding marks, so that the roughness of the outer surface of the first shell 1 and the second shell 2 meets the requirements.

[0078] In some example embodiments of the present disclosure, referring to Figure 3As shown, the second shell 2 can further include an annular baffle 26 connected to the second shell 2, the annular baffle 26 is substantially vertically arranged with the top plate 27, the annular baffle 26 and the second shell 2 can be formed by the same injection molding process, so that the sealing between the annular baffle 26 and the second shell 2 can be guaranteed. Specifically, the annular baffle 26 can include four rectangular baffles and an arc-shaped baffle, the four rectangular baffles and the arc-shaped baffle are sequentially connected end to end to form the annular baffle 26, and the adjacent two rectangular baffles and the adjacent rectangular baffle and the arc-shaped baffle are connected by a circular arc surface.

[0079] The annular baffle 26 is used to accommodate the cleaning agent or disinfectant, and the annular baffle 26 is located in the second recess 24, that is, the chamber for accommodating the cleaning agent or disinfectant is located in the chamber for accommodating clean water. If the sealing between the annular baffle 26 and the first shell 1 is poor, the cleaning agent or disinfectant will leak into the clean water, and the cleaning agent or disinfectant will be dissolved in the clean water for a long time, which will cause the effectiveness of the cleaning agent or disinfectant to decrease or even fail.

[0080] The second outlet 162 is arranged on the bottom plate 16 of the first shell 1, and the second outlet 162 is arranged opposite to the first recess 12, so that the cleaning agent or disinfectant can flow out to the cleaning part through the second outlet 162.

[0081] The second inlet 272 is arranged on the top plate 27 of the second shell 2, and the second inlet 272 is arranged opposite to the second recess 24, so that the cleaning agent or disinfectant can be injected through the second inlet 272.

[0082] The annular grooves 11 are arranged in the first recess 12, that is, two annular grooves 11 are arranged on the first shell 1; one annular groove 11 surrounds the other annular groove 11, one metal ring 3 surrounds the other metal ring 3, and one welding connection part 4 surrounds the other welding connection part 4.

[0083] The metal rings 3 cannot be connected to each other, and the connection between the metal rings 3 will cause short circuit and cannot realize the welding function.

[0084] Alternatively, the minimum space distance between the adjacent two metal rings 3 is greater than or equal to 10 mm, for example, the minimum space distance between the adjacent two metal rings 3 can be 12 mm, 15 mm, 17 mm, 20 mm, 23 mm, 25 mm, 28 mm, 30 mm, etc. In this way, the adjacent two metal rings 3 are prevented from interfering with each other, and specifically, if the distance between the adjacent two metal rings 3 is too close, the energy of one metal ring 3 will be transferred to the other metal ring 3, thereby causing excessive welding (glue overflow) at the part where the distance between the adjacent two metal rings 3 is too close, and even causing carbonization.

[0085] The end of the annular baffle 26 facing away from the second housing 2 extends at least to the opening of the annular groove 11. Similarly, a metal ring 3 is provided in the annular groove 11. Therefore, the welded connection 4 can be formed by a high-frequency induced welding process. Using the high-frequency induction heating technology based on the electromagnetic induction principle, the metal ring 3 embedded between the annular baffle 26 and the first housing 1 is inductively heated. A portion of the annular baffle 26 and the first housing 1 near the metal ring 3 is heated and melted. After cooling, a joint is formed, so that the welded connection 4 is connected to the metal ring 3, the annular baffle 26, and the first housing 1, thereby sealing the connection between the annular baffle 26 and the first housing 1 and preventing the cleaning agent or disinfectant from leaking into the clean water, so as to ensure the effectiveness of the cleaning agent or disinfectant.

[0086] Optionally, refer to Figure 2 As shown, the first housing 1 may further include a first annular baffle 14 and a second annular baffle 15; the first annular baffle 14 is connected to the first housing 1 and is located within the first recess 12; the second annular baffle 15 is connected to the first housing 1 and is located within the first recess 12; the first annular baffle 14 and the second annular baffle 15 are substantially perpendicular to the base plate 16, and the first annular baffle 14 and the second annular baffle 15 can be formed with the first housing 1 through the same injection molding process, thus ensuring the sealing between the first annular baffle 14 and the second annular baffle 15 and the first housing 1. The second annular baffle 15 surrounds the first annular baffle 14, and the second annular baffle 15 and the first annular baffle 14 are spaced apart, so that an annular groove 11 is provided between the second annular baffle 15 and the first annular baffle 14.

[0087] The annular baffle 26 extends from the end opposite to the second housing 2 into the annular groove 11. A metal ring 3 is also disposed within the annular groove 11. Therefore, the welded connection 4 can be formed using a high-frequency induced welding process. Utilizing high-frequency induction heating technology based on the principle of electromagnetic induction, the metal ring 3 embedded between the annular baffle 26, the first annular baffle 14, and the second annular baffle 15 is inductively heated.

[0105] In this case, the welded connection part 4 is connected between the metal ring 3 and the groove bottom wall and the groove side wall of the first annular groove 11a, and is connected between the metal ring 3 and the groove bottom wall and the groove side wall of the second annular groove 23, and is also connected between the connecting surface of the second shell 2 provided with the second annular groove 23 and the connecting surface of the first shell 1 provided with the first annular groove 11a.

[0109] The cross section of the metal ring 3 along the first direction X is circular, in which case, in the absence of welding, the maximum size of the metal ring 3 is arranged to be tangent to the annular groove 11, and the metal ring 3 and the corner portion of the polygon can form a containing space for containing the material of the first shell 1 or the second shell 2 after melting, so that the welding connection portion 4 formed after cooling and solidification is connected between the metal ring 3 and the first shell 1 and the second shell 2, to seal and connect the first shell 1 and the second shell 2.

[0110] Of course, in some other example embodiments of the present disclosure, the cross-sectional shape of the annular groove 11 along the first direction X can be the same as the cross-sectional shape of the metal ring 3 along the first direction X, for example, referring to Figure 8 As shown, the cross-sectional shape of the annular groove 11 along the first direction X can be rectangular, and the cross-sectional shape of the metal ring 3 along the first direction X can also be rectangular.

[0112] For example, the cross-sectional shape of the annular groove 11 along the first direction X can be semicircular, and the cross-sectional shape of the metal ring 3 along the first direction X can also be semicircular. In this case, the radius of the metal ring 3 can be smaller than the radius of the annular groove 11 when there is no welding, so that the metal ring 3 and the annular groove 11 can form a containing space for containing the molten material of the first shell 1 or the second shell 2, so that the welding connection 4 formed after cooling and solidification is connected between the metal ring 3 and the first shell 1 and the second shell 2, to seal and connect the first shell 1 and the second shell 2.
