The utility model is further described with reference to the drawings and the specific embodiments in the following description.

Example 1:

as shown in fig. 1, a water tank comprises a tank body, wherein a cavity is arranged in the tank body, the tank body comprises an upper water tank shell 1 and a lower water tank shell 2, a water tank cover 11 is arranged on the upper water tank shell 1, a water outlet 21 is arranged on the lower water tank shell 2, a filter element 22 is arranged on the water outlet 21, and a mop cloth is arranged at the lower end of the lower water tank shell 2. Open tank lid 11 and can add water in to the box cavity, when water in the box cavity passes through delivery port 21, the filter core filters it, and the filter core makes the water tension grow of here in addition, has certain effect of blocking water, prevents that water from directly revealing from delivery port 21, and the rivers that delivery port 21 came out are to the mop for the mop keeps moist, thereby can drag ground work.

As shown in fig. 2 and 4, an extrusion cavity 3 (dotted line area) is arranged at the bottom of the box body, a water through hole 33 is arranged at the lower part of the side wall of the extrusion cavity 3, the cross sectional area of the water through hole 33 is smaller than that of the water outlet 21, the inner space of the extrusion cavity 3 is communicated with the box body cavity outside the extrusion cavity 3 through the water through hole 33, an extrusion piece 4 is arranged on the extrusion cavity 3, the water outlet 21 and the filter element 22 are both positioned in the range of the extrusion cavity 3, and water in the extrusion cavity 3 is extruded out of the box body through the water outlet 21 when the extrusion piece 4 is deformed under pressure.

Integrative injection moulding has last cavity 31 in water tank epitheca 1, and the structure on the water tank epitheca 1 is regarded as the partly of last cavity 31 simultaneously, and integrative injection moulding has lower cavity 32 on the water tank inferior valve 2, and the structure on the water tank inferior valve 2 is regarded as the partly of cavity 32 down simultaneously also, and when water tank epitheca 1 and water tank inferior valve 2 lid, go up cavity 31 and lower cavity 32 and enclose to close and form extrusion cavity 3. The upper cavity 31 and the lower cavity 32 are hermetically connected at the butt joint part, so that water leakage of the extrusion cavity 3 is avoided. The water through hole 33 can be arranged on the upper cavity 31, the lower cavity 32 or both, a complete water through hole 33 is formed in a butt joint mode, the optimal position of the water through hole 33 is also arranged on the lower cavity 32, and therefore the water through hole 33 can be guaranteed to be at a lower position on the extrusion cavity 3, and when the water level in the cavity of the box body is lower, the extrusion cavity 3 can also be kept in a full water state.

When the tank body is assembled, the upper cavity 31 and the upper water tank shell 1, and the lower cavity 32 and the lower water tank shell 2 form a whole assembly, the upper water tank shell 1 and the upper cavity 31 form an upper assembly, the lower water tank shell 2 and the lower cavity 32 form a lower assembly, the integrally formed structure can reduce the number of assembled parts, the assembly difficulty is reduced, meanwhile, the layout on the tank body is fully utilized by the upper cavity 31 and the lower cavity 32, namely, a part of structure is shared between the upper water tank shell 1 and the upper cavity 31 or between the lower water tank shell 2 and the lower cavity 32, the structure is simplified, and materials are saved. When going up subassembly and lower subassembly equipment, water tank epitheca 1 and water tank inferior valve 2 dock mutually and form the box, go up cavity 31 and cavity 32 and also just in time dock mutually and form extrusion cavity 3, only need one step just in place the mountable, need not independent installation, reduce the equipment degree of difficulty, design into the components of a whole that can function independently structure of subassembly and lower subassembly simultaneously, conveniently install and remove, can install or change other parts such as extruded article 4, filter core 22 on box or extrusion cavity 3 conveniently like this.

In the embodiment, an extrusion cavity 3 with a smaller volume relative to the box body is separately arranged in the box body, the extrusion cavity 3 is positioned at a lower position in the box body, the position of a water through hole 33 on the extrusion cavity 3 is arranged at the lowest height on the extrusion cavity 3, water in a cavity of the box body flows into the extrusion cavity 3 through the water through hole 33, and extrusion rubber is adopted as the extrusion piece 4. Through doing extrusion spare 4, delivery port 21, filter core 22 in an extrusion cavity 3, extrusion cavity water 3 is pushed out the back, and the water in the box cavity can supply into, so 3 inside water of extrusion cavity is full, extrudees the extrusion rubber of water tank bottom, can keep unanimous around the pressure change in the extrusion cavity 3, and the pressure that filter core 22 department bore is also the same to delivery port 21 department goes out water evenly. The pressure change in the extrusion cavity 3 mainly comes from the extrusion force of the extrusion piece 4, and when the extrusion piece 4 extrudes, because the limber hole 33 is smaller, the instantaneous pressure generated by the extrusion piece 4 makes water flow out from the larger water outlet 21 preferentially, and the water tank normally discharges water. Because the extrusion cavity 3 is a relatively independent structure and is filled with water, the water level or water pressure change in the cavity of the box body has little influence on the pressure change in the extrusion cavity 3, and when the water level in the cavity of the box body gradually becomes low, the pressure change generated by the extrusion of the extrusion cavity 3 by the extrusion piece 4 can basically keep consistent front and back, thereby ensuring that the water outlet at the water outlet 21 is even.
