Description
Technical Field
[0001] The invention relates to the technical field of sweeping robots, and in particular to a novel automatic water-adding mechanism with an anti-drip function. Background Art
[0002] With the development of science and technology, sweeping robots have entered thousands of households. However, the sweeping robots currently on the market are usually robots for vacuuming and cleaning dry garbage. There are fewer sweeping robots that need to clean and mop the floor. In the sweeping robots that clean and mop the floor, clean water needs to be added. The clean water of some sweeping robots needs to be added manually, which is time-consuming and labor-intensive. For this reason, some sweeping robots that can automatically add clean water have appeared on the market. However, when adding clean water, such robots often cause the residual water in the water adding pipe to drip onto the robot when the sweeping robot leaves. After the robot leaves, the water drips onto the ground or the water adding seat. Over time, the water adding seat will be wetted, and the water will enter the electrical main board, causing damage to the main board. For this reason, according to the needs of such robots, the applicant has designed and produced a new automatic water adding mechanism with anti-drip function. This mechanism can realize the full-automatic water adding of the sweeping robot, and can effectively prevent the leakage of clean water during the water adding process, providing comprehensive protection and ensuring the normal use of the sweeping robot.

[0010] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: like Figure 1-2 As shown, a new automatic water adding mechanism with anti-drip function is shown, including a water adding seat shell 1, a water adding nozzle 2, a water receiving tank 3, a spring 4, a guide flange pipe 5, a limit switch 6, an electric push rod 7 and a water adding pipe 8, as shown Figure 1 As shown, the new automatic water-adding mechanism with anti-drip function is provided with a water-adding seat shell 1, and the water-adding seat shell 1 is made of environmentally friendly plastic injection molding. The water-adding seat shell 1 is a square structure, and a buckle installed with the base of the sweeping robot is provided at the tail end. A drainage groove 1-1 is provided at the lower part of the water-adding seat shell 1, and a drain port 1-2 is provided at the lower tail of the water-adding seat shell 1. A water-adding nozzle 2 and a water receiving trough 3 are installed in the water-adding seat shell 1. A limiting bolt 2-1 and a drain hole 2-2 are provided at the front end of the water-adding nozzle 2. The limiting bolt 2-1 can be limited and pulled back by connecting to the water trough 3, and the drain hole 2-2 can realize the discharge of excess water in the water-adding nozzle 2. 3 is provided with an inclined groove 3-1 at the lower part, and the inclined groove 3-1 can accelerate the discharge of water flow; a guide flange pipe 5 is provided in the middle part of the water adding nozzle 2, and the water adding nozzle 2 is arranged inside the guide flange pipe 5. A spring 4 is provided outside the guide flange pipe 5, and the spring 4 is in a compressed state to provide an outward thrust to the water receiving groove 3; the water receiving groove 3 is located outside the guide flange pipe 5, and a limit switch 6 and an electric push rod 7 are provided at the rear part of the water adding nozzle 2. The limit switch 6 controls the extension and retraction length of the water adding nozzle 2, and the electric push rod 7 provides the water adding nozzle 2 with the power of extension and retraction. The rear end of the water adding nozzle 2 is connected to the water adding pipe 8, and the water adding nozzle 2 can move in the guide flange pipe 5.
[0011] like Figure 3-6 As shown, when the new automatic water-adding mechanism with anti-drip function is in standby state, the water-adding nozzle 2 and the water receiving tank 3 are retracted into the water-adding seat shell 1, and the water-adding nozzle 2 and the water receiving tank 3 are hidden in the water-adding seat shell 1; when the sweeping robot reaches the water-adding base of the sweeping robot, the sweeping robot determines through communication that water needs to be added, and the control panel of the sweeping robot base applies an electric signal and current to the electric push rod 7 of the new automatic water-adding mechanism with anti-drip function, at which time the electric push rod 7 pushes the water-adding nozzle 2 forward, and at this time the water receiving tank 3 is pushed out synchronously with the water-adding nozzle 2 under the action of the spring 4, and the process state is as shown in FIG. Figure 4As shown, after the water adding nozzle 2 reaches the water adding port of the sweeping robot, the water adding nozzle 2 continues to move forward and extends into the water adding port of the sweeping robot. At this time, the front end of the water receiving tank 2 is close to the water adding port of the sweeping robot under the obstruction of the external structure of the water inlet of the sweeping robot, and the limit switch 6 at the rear end of the water adding nozzle 2 controls the extension length of the water adding nozzle 2. The schematic diagram is shown in FIG. Figure 6 When the water filling nozzle 2 is fully extended, as shown in Figure 3 As shown, after the docking is completed, the water filling pipe at the rear end of the water filling nozzle 2 supplies water to the sweeping robot. After the sweeping robot detects that the water is full, a signal is given to the base of the sweeping robot to activate the solenoid valve installed on the water filling pipe 8 to stop the water supply. Then the control board of the base of the sweeping robot gives an electrical signal and current to the electric push rod 7, and the electric push rod 7 retracts backward. At this time, the water filling nozzle 2 is retracted backward. When the water filling nozzle 2 is separated from the water filling port of the sweeping robot, the limit bolt 2-1 on the water filling nozzle 2 docks the water tank 3 to provide a limiting force, so that it retracts backward synchronously with the water filling nozzle. At this time, the residual water in the water filling nozzle 2 flows into the inclined groove 3-1 of the water receiving tank 3 through the drain hole 2-2, and then flows into the drainage groove 1-1 at the bottom of the water filling seat shell 1, and finally is discharged through the drain port 1-2. When the water filling nozzle 2 is completely retracted into the water filling seat shell 1, the limit switch 6 is triggered, and the electric push rod 7 stops and completes the retraction. Figure 5 shown.
