[0026] Please refer to Figures 1 to 4 , the water level sensing control box 31 is also provided with a delay circuit 38, the delay circuit 38 is connected with the signal core column 32 and the control circuit of the water pump 21, in the drainage system, the water level may change due to some temporary fluctuations or interference, resulting in instantaneous change of the signal of the signal core column 32, the delay circuit 38 can filter these instantaneous signal changes, only when the water level continuously decreases to a certain extent and reaches the set delay time, the signal of stopping the water pump 21 will be triggered, so as to avoid the water pump 21 from being frequently started and stopped due to accidental fluctuations of the water level, improve the stability and reliability of the system, reduce the wear and tear of the equipment and energy consumption.
[0027] Please refer to Figures 1 to 4 , the water pump 21 is provided with an expansion disc 6 at the bottom, the expansion disc 6 is provided with a through cavity around the periphery, the expansion disc 6 is provided with a connecting column 61 at the center, the expansion disc 6 is installed at the bottom of the water pump 21 in a screw manner through the connecting column 61 at the upper end, by virtue of the large lateral support area of the expansion disc 6, the contact range of the bottom of the water pump 21 and the placement plane is significantly increased, the gravity of the water pump 21 and the reaction force generated during work are effectively dispersed, so that the water pump 21 can keep balance during operation, reduce the risk of tilting caused by unstable gravity center, at the same time, through the screw installation, the subsequent disassembly work of the expansion disc 6 is facilitated.
[0028] When the pool body 1 is used without water or with less water, the floating block 34 is in a lower position, the top core 33 does not contact the triggering end of the signal core column 32 (micro switch), and the water pump 21 is in a closed state. When the water level in the pool body 1 gradually rises, the floating block 34 is affected by the water buoyancy and moves upward along the guide rod 35. Because the guide rod 35 is vertically fixedly installed on both sides of the water level sensing control box 31 and penetrates the guide holes on both sides of the floating block 34, the guide rod 35 can guide the movement of the floating block 34. With the rising of the floating block 34, the top core 33 on the upper end thereof gradually approaches and finally triggers the triggering end of the signal core column 32 (micro switch). At this time, the micro switch is triggered to generate an electrical signal, and the electrical signal generated by the signal core column 32 is transmitted to the delay circuit 38 in the water level sensing control box 31. The delay circuit 38 starts to work. The function of the delay circuit 38 is to prevent the water pump 21 from being frequently started due to temporary fluctuation of the water level. After a certain delay time, if the water level still remains at a high position, that is, the top core 33 still triggers the micro switch, the delay circuit 38 will only send a start signal. When the delay circuit 38 sends a start signal, the signal is transmitted to the control circuit of the water pump 21 through the wire 5. The water pump 21 is started. The water inlet port 23 of the water pump 21 is downwardly arranged, which can suck the water in the pool body 1 through the water inlet port 23. The water inlet port 23 is provided with a filter screen. The filter screen is made of stainless steel and has a mesh diameter of 2-5 mm, which can effectively filter impurities in the water to prevent the impurities from entering the water pump 21 and causing blockage and damage. Then the water is discharged out of the pool body 1 through the drain pipe 22. Because the water pump 21 is provided with the expansion disc 6 at the bottom, the expansion disc 6 is provided with a through cavity around the expansion disc 6, which is helpful to expand the water pumping range and improve the water pumping efficiency. With the water pumping of the water pump 21, the water level in the pool body 1 gradually decreases, and the floating block 34 also decreases. When the floating block 34 decreases to a certain extent, the top core 33 is separated from the triggering end of the signal core column 32, the micro switch returns to the initial state, and the electrical signal disappears. After the electrical signal disappears, if the water level remains at a low position for a certain time, the delay circuit 38 will send a stop signal to the control circuit of the water pump 21 through the wire 5, and the water pump 21 stops working, completing a water discharge process. The technology of the delay circuit 38 for controlling the water pump 21 to stop working is based on the common signal delay and judgment principle in the existing electronic circuit field. Through the time monitoring after the electrical signal disappears, the logic judgment function is realized. This technology has been widely used in the start-stop control of various equipment in the automatic control field and is a mature technical means familiar to those skilled in the art, which will not be described in detail here.
[0029] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
