[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Example:

[0035] See also Figure 1-6 A water tank structure with automatic filtering and sewage discharge functions includes a tank body 1, a water supply pipe 2 is provided on the top of the tank body 1, the bottom end of the water supply pipe 2 extends to the middle and lower part of the tank body 1, and a horizontal filter 3 is provided. A sewage discharge pipe 4 is provided at one end of the filter 3, and one end of the sewage discharge pipe 4 extends to the outside of the tank body 1;

[0036] The filter 304 is provided with a filter screen 304 between the mounting seat 303 and the drain interface 302. The outer periphery and inner side of the filter screen 304 are fixedly mounted with an outer square hole mesh 305 and an inner square hole mesh 306 respectively to increase the strength of the filter screen 304 and ensure the strength requirements of the filter 3 under both filtering and backwashing conditions. In addition, the outer square hole mesh 305 and the inner square hole mesh 306 are selected with specifications greater than the filtering accuracy to ensure the flow rate of the filter screen 304. The plug 301 and the drain interface 302 are connected to the water supply pipe 2 and the drain pipe 4 respectively. When in use, the filter 3 is placed horizontally, the filter screen 304 is concentrated in the smallest horizontal space, and the filter 3 is placed in the middle and lower part of the box body 1. The filter screen 304 can be backwashed by the water stored in the box body 1 to improve the cleaning effect.

[0037] See Figure 3 and Figure 4 The filter screen 304 adopts a single-layer structure, which does not affect the water storage space of the box 1, and has a cylindrical shape with a diameter several times that of the water supply pipe 2. The filtering area is much larger than the water supply port area.

[0038] See Figure 4 The cross section of the filter 304 is a wave-shaped structure and is made of stainless steel wire. When in use, the filter 304 is woven from stainless steel wires of different diameters. It has the characteristics of high porosity, high dirt holding capacity, good strength, not easy to fall off, and easy to clean.

[0039] See Figure 2 A water supply port is provided at the top of the plug 301, and a sewage outlet is provided at one end of the sewage interface 302.

[0040] See Figure 2 The water supply port on the plug 301 and the sewage outlet on the sewage interface 302 are respectively connected to the water supply pipe 2 and the sewage pipe 4 with flat thin flanges and fixed by a clamp 5, which is simple to disassemble and convenient for maintenance.

[0041] See Figure 1 A water supply valve 6 is installed on the periphery of one end of the water supply pipe 2 located outside the box body 1, and a sewage valve 7 is installed on the periphery of one end of the sewage pipe 4 located outside the box body 1.

[0042] Working principle:

[0043] Filtration working condition: Raw water containing foreign matter enters the filter screen 304 of the filter 3 through the water supply pipe 2. The diameter of the filter screen 304 is larger than that of the water supply pipe 2, which greatly reduces the water flow speed and is conducive to improving the filtration effect. At this time, foreign matter larger than the gaps in the woven mesh is intercepted inside the filter screen 304, and clean water enters the box body 1 through the filter screen 304 and the outer square hole mesh 305. At this time, the clean water source stored in the box body 1 meets the requirements of the pressure pump, completing the automatic filtration of the replenished water source;

[0044] Sewage discharge working condition: As the water replenishment and filtration are continuously carried out, the filtered foreign matter accumulates, and the filter 304 needs to be discharged and flushed. The sewage valve 7 is opened, and the foreign matter is discharged from the filter 3 along the sewage pipe 4 under the action of water pressure. Water is replenished during sewage discharge, and the replenishment water flow can be used to flush the inside of the filter 304; if water is not replenished during sewage discharge, the water stored in the box 1 can be used to achieve a backwashing effect, which greatly improves the convenience of cleaning the inside of the box 1.

[0045] The sewage discharge time should be selected when the water replenishment is completed. Within the preset time, first open the sewage discharge valve 7, then open the water replenishment valve 6, then close the sewage discharge valve 7, and then close the water replenishment valve 6 to complete a sewage discharge cycle;

[0046] Maintenance: During maintenance, loosen the two clamps 5 on the water supply pipe 2 and the sewage pipe 4, and the water filter 3 can be taken out from the box 1 for cleaning. After cleaning, reinstall the water filter 3 into the box 1 and fix the two clamps 5.

[0047] Finally, it should be noted that in the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0048] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components.
