A mounting plate 62 is installed on the outer side of the floating ball 61. Both sides of the mounting plate 62 are fixedly connected with floating plates 63. A first through groove 68 is opened on the floating ball 61. A multi-telescopic sleeve 64 is fixedly sleeved inside the first through groove 68. One end of the multi-telescopic sleeve 64 is connected to the water supply pipe 4. By setting the floating mechanism 6, the replenished water can be directly introduced into the remaining water in the main body 1 of the mixed water direct supply unit, so as to avoid the situation in which the potential energy of the water flow impacts the main body 1 of the mixed water direct supply unit and causes damage to it during the direct replenishment process. By setting the disassembly and assembly mechanism 7, it is convenient to disassemble and replace the floating ball 61.

[0026] Reference Figure 2 , Figure 3 and Figure 4The disassembly and assembly mechanism 7 includes a through groove 71 and two clamping grooves 72. The through groove 71 and the two clamping grooves 72 are both provided on the upper surface of the mounting plate 62. The through groove 71 and the two clamping grooves 72 are mutually connected. The two sides of the floating ball 61 are fixedly connected with clamping blocks 73. The clamping groove 72 matches the clamping block 73. A telescopic groove 74 is provided on the inner wall of the clamping groove 72. A positioning groove 75 is provided at the bottom end of the telescopic groove 74. A cavity rod 76 is fixed inside the positioning groove 75. A spring 77 and a linkage plate 78 are provided inside the cavity rod 76.

When the linkage plate 78 moves, it will drive the positioning rod 79 to move synchronously and compress the cavity rod 76 until the positioning rod 79 is released from the second through groove 791 and The inside of the locking groove 792 is extended out, and then the floating ball 61 is pulled upward, and the floating ball 61 can be disassembled from the mounting plate 62; if installation is required, after repeating the above steps, the floating ball 61 is inserted into the through groove 71, so that the two locking blocks 73 are correspondingly inserted into the inside of the two locking grooves 72, and then the toggle block 783 is released. At this time, under the action of the restoring force of the spring 77, the positioning rod 79 can pass through the second through groove 791 and be inserted into the inside of the locking groove 792, thereby completing the quick installation between the floating ball 61 and the mounting plate 62.

[0027] Reference Figure 2 Limiting grooves 65 are provided on both sides of the inner wall of the main body 1 of the mixed water direct supply unit, one end of the floating plate 63 is slidably connected to the inside of the limiting groove 65, and a fixing plate 67 is fixedly connected to the outer side of the multiple telescopic sleeve 64, and one end of the fixing plate 67 is connected to the inner wall of the main body 1 of the mixed water direct supply unit. By setting the limiting groove 65, the floating plate 63 can be limited, and then when the water level rises or falls, the floating ball 61, the mounting plate 62 and the floating plate 63 can move vertically. By setting the fixing plate 67, the top of the multiple telescopic sleeve 64 can be limited, thereby increasing its stability.

[0028] Reference Figure 2 A mounting groove is provided on the lower surface of the floating plate 63, and an air bag 66 is fixedly sleeved inside the mounting groove. By providing the air bag 66, the buoyancy of the floating plate 63 can be increased, so that the floating plate 63 contacts the liquid surface in the mixed water direct supply unit body 1.

[0029] Reference Figure 3 and Figure 4 A sealing plate 784 is fixedly connected to one side of the toggle block 783. The cross-sectional area of ​​the sealing plate 784 when viewed from above is larger than the cross-sectional area of ​​the track groove 782 when viewed from above. The sealing plate 784 can shield the track groove 782, thereby achieving a waterproof effect.

[0030] Reference Figure 3 There are two sealing plates 784, and the bottoms of the two sealing plates 784 are fixedly connected with a pulling plate 785, and the upper surface of the pulling plate 785 is fixedly connected with a handle 786. By setting the pulling plate 785, when the pulling plate 785 is pulled, the two positioning rods 79 can be driven to move synchronously, thereby facilitating the disassembly of the floating ball 61 and the mounting plate 62. By setting the handle 786, it is convenient to pull the pulling plate 785.

[0031] Working principle: During use, the water inside the mixed water direct supply unit body 1 decreases, causing the water level to drop. When the water level drops, the floating plate 63 can always keep in contact with the water surface through the expansion and contraction of the multiple telescopic sleeves 64. When the water level drops to a certain value, the water level inside the mixed water direct supply unit body 1 is monitored in real time by setting the sensor 2, and the water supply pump 3 and the control valve 5 can be automatically opened. Then, under the action of the water supply pipe 4, water can be transported to the inside of the mixed water direct supply unit body 1. When water is transported through the water supply pipe 4, the water is directly transported to the mixed water direct supply unit body 1 through the multiple telescopic sleeves 64 and the floating ball 61. The water inside the bottom of the direct-supply unit body 1 can play a certain buffering role through the remaining water in the mixed water direct-supply unit body 1, so as to avoid the situation where the water directly replenishes into the mixed water direct-supply unit body 1 and causes impact on the mixed water direct-supply unit body 1 under the influence of the water flow potential energy, causing damage to the mixed water direct-supply unit body 1. As more and more water is replenished, the water level also rises accordingly. When the water level rises, the floating plate 63 will be lifted, thereby driving the floating ball 61 to move upward synchronously, causing the multiple telescopic sleeves 64 to shrink. When the water level reaches a certain height, the water replenishment pump 3 and the control valve 5 can be automatically closed by setting the sensor 2.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
