The annular water distribution ring 2 is hollow inside and forms an annular water channel. The annular water distribution ring 2 is provided with a water inlet interface that is connected to the annular water channel.

[0037] Connecting cover plate 3 covers the annular water distribution ring 2, and connecting cover plate 3 connects the vessel body 1 and the upper cover respectively;

[0038] Drive mechanism 4 is mounted on the upper cover. Drive mechanism 4 has a drive end and a drive gear that is suitable for meshing with the internal meshing teeth of the annular water distribution ring 2.

[0039] The cleaning assembly includes multiple cleaning spray bars 51 and multiple nozzles 52. The cleaning spray bars 51 are evenly spaced along the lower end of the annular water distribution ring 2 and are connected to the annular water channel. The nozzles 52 are detachably and spaced along the length of the cleaning spray bars 51 on the corresponding cleaning spray bars 51.

[0040] In this embodiment, as Figures 1-2 As shown, the top cover is first installed on the vessel body 1. Then, a rotatable annular water distribution ring 2 is set on the vessel body 1. The driving mechanism 4 drives the annular water distribution ring 2 to rotate back and forth within a certain angle range. At this time, the cleaning spray bar 51 and nozzle 52, which are uniformly arranged circumferentially at the lower end of the annular water distribution ring 2 and connected to the annular water channel of the annular water distribution ring 2, start to work. Water enters the annular water channel through the water inlet and is then sprayed onto the inner wall of the vessel body 1 through the cleaning spray bar 51 and nozzle 52. During the rotation of the annular water distribution ring 2, the inner wall of the vessel body 1 can be cleaned without dead angles, which significantly improves the cleaning effect and cleaning efficiency.

[0041] Specifically, such as Figures 3-5 As shown, the cleaning spray bar 51 includes:

[0042] The outer tube 511 is a hollow cylinder. The inner wall of the outer tube 511 is provided with a semi-circular groove extending along the axis. The semi-circular groove extends axially and terminates at the lower end face of the outer tube 511. The outer tube 511 is connected to the annular water channel.

[0043] The inner tube 512 is a hollow cylinder and is slidably disposed inside the outer tube 511. The outer wall of the inner tube 512 is provided with a semi-circular protrusion that matches the semi-circular groove.

[0044] The outer tube 511 has multiple first radial holes arranged at equal intervals along the axial direction on its wall surface, and the inner tube 512 has multiple second radial holes arranged at equal intervals along the axial direction on its wall surface. Both the first radial holes and the second radial holes are connected to the annular water passage.

[0045] The inner tube body 512 is adapted to be fixed relative to the outer tube body 511 by sequentially passing through the first radial hole of the outer tube body 511 and the second radial hole of the inner tube body 512 through the fixing member.

[0046] Specifically, as shown in Figure 3 the nozzle 52 is a fan-shaped nozzle.

[0047] In the present embodiment, as shown in Figure 1 and Figures 3-5 when it is necessary to adjust the height position of the nozzle 52, it can be achieved by adjusting the sliding position of the inner tube body 512 in the outer tube body 511, by aligning the corresponding first radial hole and second radial hole, and then fixing by using the fixing member, so as to meet the cleaning requirements of different height positions. The remaining first radial holes and second radial holes are installed with the nozzle 52.

[0048] In the working process of the cleaning spray rod 51, the cleaning liquid first enters the inside of the outer tube body 511 from the annular waterway, then enters the inner tube body 512 through the communication path of the outer tube body 511 and the inner tube body 512, and finally is sprayed out from the fan-shaped nozzle 52. The design of the fan-shaped nozzle 52 can produce a fan-shaped water flow, provide a larger cleaning coverage area, and at the same time can also increase the water flow impact force, improve the cleaning effect. During the reciprocating rotation of the annular water distribution ring 2, the plurality of fan-shaped nozzles 52 can realize omnidirectional cleaning of the inner wall of the kettle body 1. In addition, the fan-shaped spray surface of the fan-shaped nozzle 52 extends in the vertical direction. The cleaning liquid can be water or other solutions that can dissolve residues.

[0049] Secondly, a sealing member is also arranged at the connection between the lower end of the inner tube body 512 and the outer tube body 511, which can be a sealing ring.

[0050] In addition, in some embodiments, a fastener can also be used to pass through the first radial hole of the outer tube body 511 and abut against the outer wall of the inner tube body 512 to limit the movement of the inner tube body 512.

[0051] Specifically, as shown in Figure 1 the driving mechanism 4 comprises:

[0052] a driving source, the driving source being mounted on the upper cover;

[0053] a speed reducer, the input end of the speed reducer being connected with the output shaft of the driving source, and a driving gear being fixedly installed on the output shaft of the speed reducer.

[0054] Specifically, as shown in Figures 1-2 the driving source is a motor.

[0055] In the present embodiment, as shown in Figure 2As shown, after the driving source is started, the high-speed low-torque movement is converted into low-speed high-torque output through the speed reducer, and then the annular water distribution ring 2 is driven to reciprocate by the driving gear.

[0056] Secondly, in other embodiments, a frequency converter can be additionally arranged between the driving source and the controller, and the movement speed of the annular water distribution ring 2 is controlled by adjusting the motor speed to adapt to different cleaning working conditions.

[0057] Specifically, the water inlet interface is provided with an adjusting valve (not shown in the figure).

[0058] In the embodiment, the adjusting valve adopts a manual operation mode, and the water amount entering the annular waterway can be controlled according to the actual cleaning needs. In the use process, the operator can adjust the water inlet pressure according to the pollution degree of the inner wall of the kettle body 1. For slight pollution, the adjusting valve opening can be adjusted to be small, and a smaller water flow is used for cleaning. For stubborn stains, the adjusting valve opening can be adjusted to be large, and a larger impact force is used for cleaning. The setting of the adjusting valve also has a safety protection effect. When an abnormality occurs, the water source can be quickly cut off through the adjusting valve to prevent accidents.

[0059] Secondly, in other embodiments, an electric adjusting valve can be used to replace the manual adjusting valve and be connected with the controller to realize automatic control. In addition, a pressure gauge and a flowmeter can be additionally arranged at the front end of the adjusting valve to monitor the water inlet parameters in real time and provide intuitive reference data for the operator.

[0060] Specifically, as shown in the figure, Figures 1-2 The connecting cover plate 3 has a U-shaped structure, the lower end of the connecting cover plate 3 is provided with an annular groove suitable for accommodating the annular water distribution ring 2, and the opening part of the U-shaped structure of the connecting cover plate 3 corresponds to the position of the water inlet interface of the annular water distribution ring 2.
