Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a butt sealing device for a water nozzle of a cleaning machine. Background Art

[0002] In order to clean the inside of the workpiece, a water nozzle can be installed on the workpiece. After the workpiece is positioned in the cleaning machine, it is connected to the water nozzle through a docking device, and the cleaning water flow is introduced into the workpiece to flush the inside of the workpiece. After cleaning is completed, compressed air can also be introduced into the workpiece to blow out the residual cleaning liquid inside the workpiece to achieve rapid drying.

[0003] In the process of connecting the docking device and the faucet, a sealing ring needs to be installed for sealing, and the sealing ring and the faucet must fit tightly to achieve sealing of high-pressure water flow. This makes it difficult to plug the docking device and the faucet together, and the sealing ring is easily pulled out during disassembly. Repeated plugging and unplugging will accelerate the damage of the sealing ring, resulting in sealing failure, which needs to be improved. Utility Model Content

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1~Figure 2 , the embodiments of the present utility model include:

[0018] like Figure 1 The cleaning machine shown uses a water nozzle docking and sealing device to achieve docking and sealing with the water nozzle 10, including: a driving mechanism and a docking assembly, the driving mechanism is connected to the docking assembly, drives the docking assembly to rise and fall and / or swing, and docks or disassembles the docking assembly with the water nozzle 10.

[0019] The docking assembly includes a piston 7, a cylinder 3, a spring 13, an end cover 6, a first sealing ring 9 and a trachea connector 5. The end cover 6 is arranged on the top of the cylinder 3. In this embodiment, a screw 16 connected to the cylinder 3 is provided on the end cover 6, and the structure is stable and easy to disassemble and assemble.

[0020] The trachea connector 5 is arranged on the end cap 6, and a connection port 15 corresponding to the trachea connector 5 and communicating with the interior of the cylinder 3 is provided on the end cap 6, which facilitates the assembly of the trachea connector 5. The trachea connector 5 is externally connected to a compressed air hose, which can be controlled by a solenoid valve.

[0021] like Figure 1 As shown, the piston 7 is set in the cylinder 3, and a second sealing ring 14 is set on the outer circle of the piston 7, which has good air tightness and can drive the piston 7 downward through air flow. After the solenoid valve opens the air supply path, compressed air enters the cylinder 3 through the air pipe joint 5 to achieve the downward drive of the piston 7. Figure 2 As shown, the spring 13 is arranged in the cylinder 3 and is located below the piston 7, which elastically supports the piston 7 and drives it to rise and reset. After the solenoid valve opens the exhaust passage, the piston 7 rises under the action of the spring 13, and the air above the piston 7 is discharged through the air pipe joint 5.

[0022] A water pipe connector 4 is located on top of the piston 7 and extends upward through the end cap 6. In this embodiment, this connector is connected to an external water supply line, delivering cleaning water to the nozzle 10. A guide hole corresponding to the water pipe connector 4 is provided in the end cap 6 to guide the lifting and lowering of the water pipe connector 4. A third sealing ring 17 is installed in the guide hole to prevent air leakage.

[0023] A stepped hole 12 corresponding to the water nozzle 10 is provided at the bottom of the cylinder 3, and the first sealing ring 9 is provided on the upper part of the stepped hole 12. The inner hole of the first sealing ring 9 is larger in the natural state, which does not affect the insertion and removal of the water nozzle 10 and is easy to operate.

[0024] like Figure 2 As shown, a stepped shaft 11 pointing downward to the first sealing ring 9 is provided at the bottom of the piston 7. In this embodiment, the piston 7, the stepped shaft 11 and the water pipe connector 4 can adopt an integrated structure, so that the stepped shaft 11 and the water pipe connector 4 can be raised and lowered with the piston 7. Figure 1 As shown, after the stepped shaft 11 descends, it compresses the first sealing ring 9, ensuring close contact between the inner ring of the first sealing ring 9 and the outer wall of the faucet 10, thereby improving the sealing performance. In addition, the bottom surface of the inner cavity of the cylinder 3 is used to limit the descent of the stepped shaft 11, thereby preventing the first sealing ring 9 from being subjected to excessive force.

[0025] In this embodiment, the drive mechanism includes a rotary cylinder 1 and a swing arm 2. The swing arm 2 is positioned between the top of the rotary cylinder 1 and the end cap 6. The water nozzle 10 is mounted on the workpiece. The rotary cylinder 1 drives the swing arm 2 and the end cap 6 to rotate above the water nozzle 10 and then descend, causing the stepped hole 12 to move downward and fit over the water nozzle 10, completing the docking. Compressed air is then introduced through the air pipe connector 5 to drive the piston 7 downward, driving the stepped shaft 11 downward to compress and seal the first sealing ring 9. A through hole 8 is provided in the stepped shaft 11, extending upward through the piston 7 and communicating with the water pipe connector 4. This allows water to be fed into the water nozzle 10 for cleaning the workpiece. After cleaning, the workpiece can be ventilated for dewatering and drying.

[0026] In summary, the utility model provides a sealing device for docking a water nozzle of a cleaning machine, which realizes rapid docking and automatic sealing with the water nozzle, thereby improving the sealing effect and sealing reliability.

[0027] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
