1. A foam tank structure improvement, including: a foam tank, in which a manhole and a hole cover is individually placed at one or two side tank walls thereof, and a foam injection hole, an inlet opening, and a drain opening are individually placed at the upper and lower tank walls of the foam tank;
1. A foam tank structure improvement, including: a foam tank, in which a manhole and a hole cover is individually placed at one or two side tank walls thereof, and a foam injection hole, an inlet opening, and a drain opening are individually placed at the upper and lower tank walls of the foam tank;a bag, which is a cross shape hollow bag body installed within the foam tank, and include upper and lower ends which individually connect with the foam injection holes, and the bag has double bag walls forming interlayer space therebetween, and plural anti-wear floating items integrate within the interlayer space;a foam tube, which defines a cross form tube body, and integrated within the bag, in which the upper and lower ends individually connect to the foam injection holes of the foam tank, and the tube wall is installed with plural open-apertures. 2. The foam tank structure improvement as claimed in claim 1, in which a shunt ring is installed at the inside tank wall of the inlet opening of the foam tank, the shunt ring matches the ring body at the inside tank wall of the foam tank, a retaining ring is individually outwardly installed at each of two sides thereof, a flume is formed between the two retaining rings, and plural weep holes are placed at the retaining ring. 3. The foam tank structure improvement as claimed in claim 2, in which a spreader plate is individually installed at each of two sides of the top of the shunt ring near the inlet opening, and plural notches are placed at two sides of the spreader plate. 4. The foam tank structure improvement as claimed in claim 1, in which the foam tube includes plural segments of tubes and annular tube fittings, the tube wall of every segment of the tube are installed with plural open-apertures, the foam tube uses a four-way connector to define a cross component form, the upper and lower ends individually fix at the foam injection holes placed at the upper and lower tank walls of the foam tank, and two side ends individually extend at the inner side of one or two sides of the hole cover. 5. The foam tank structure improvement as claimed in claim 4, in which a convex bushing is installed at the inside center of the hole cover, and the bushing fits with one side end of the foam tube. 6. The foam tank structure improvement as claimed in claim 1, in which the foam tube includes plural tubes connected through directly screwing each other, wherein external thread is installed at one end of each tube, and internal thread is installed at another end, through the external thread and the internal thread screwing each other, the foam tube uses a four-way connector to define a cross component form, and plural open-apertures are placed at the tube wall of every segment of the tube, thus the upper and lower ends are fixed at the foam injection holes placed at the upper and lower tank walls of the foam tank, and the two side ends individually extend at the inner side of one or two sides of the hole cover. 7. The foam tank structure improvement as claimed in claim 6, in which the convex bushing is installed at the inside center of the hole cover, and the bushing fits with one side end of the foam tube. 8. The foam tank structure improvement as claimed in claim 1, in which a complement tank is installed at the outside of the foam tank, a pump integrates with the complement tank, and the pump integrates with a transit tube connecting with the foam injection hole. 9. The foam tank structure improvement as claimed in claim 8, in which a sensor is installed at the foam tank, and the sensor controls the starting and stop for the pump. 10. The foam tank structure improvement as claimed in claim 9, in which the foam tank is installed with a distribution device for controlling the flow ratio of the foam liquid, the distribution device is a multi-hole connector, and the two end holes individually connect with a water supply pipe and a mixed liquid feed tube, through the mixed liquid feed tube integrating with the sensor, the sensor is used for the flow sensor to detect the flow. 11. The foam tank structure improvement as claimed in claim 10, in which the mixed liquid feed tube integrates with a non-return valve.
