[0014] According to another aspect of the present invention, a method for cleaning a pipeline of a milk tea machine is provided, comprising the following steps:

[0015] S01: Add cleaning liquid into the liquid storage tank through the liquid adding pipe, and the motor works to rotate the shaft and the stirring rod to mix the cleaning liquid;

[0016] S02: By rotating the connector, the connecting pipe can be connected and fixed to the liquid storage tank and the input end of the device body under the action of the thread engagement between the connector and the connector, and the sealing ring cooperates with the sealing groove for sealing. Repeat the above operation to connect and seal the two ends of the discharge pipe with the output end of the device body and the pipeline inlet of the milk tea machine body, and the two ends of the discharge pipe with the pipeline outlet of the milk tea machine body and the collection box;

[0017] S03: Through the operation of the device body, the cleaning liquid in the liquid storage tank can be drawn into the pipeline of the milk tea machine body through the connecting pipe and the liquid inlet pipe. At this time, the electric control valve 1 is in a closed state, the electric control valve 2 is in an open state, and the compressed air pump works to pass the compressed air through the aeration head on the inflation pipe to generate fine bubbles into the cleaning pipeline of the milk tea machine body. The aeration head and the impeller can be rotated to stir the cleaning liquid in the cleaning pipeline.

The sealing plate and the installation frame can be pulled out to clean the filter.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The auxiliary aeration mechanism can cooperate with the main body of the device, which can facilitate the introduction of fine bubbles when using traditional cleaning liquid for cleaning. At the same time, it can drive the impeller on the aeration head to rotate, and can drive the cleaning liquid in the pipeline to stir, so that the bubbles can rise in the water and finally burst, which will generate tiny turbulence and shock waves. These shock waves can effectively break the dirt layer on the pipe wall, loosen it and fall off. The presence of bubbles increases the fluidity and turbulence of water, making the water flow more active, which helps to better cover and flush the pipe wall, thereby enhancing the cleaning effect. After cleaning, the auxiliary aeration mechanism can be used to dry the inside of the pipeline for subsequent use.

[0023] 2. The provided mixing assembly can be used to assist in mixing and stirring the cleaning liquid inside the liquid storage tank to ensure its uniform distribution, which is convenient for subsequent extraction and cleaning of the pipeline.

The connecting mechanism between the liquid storage box 3 and the connecting pipe 4 is taken as an example. The mechanism includes a connector 13 welded on the side wall of the liquid storage tank 3, and a connector 11 is welded on the end of the connecting pipe 4 and is threadedly engaged with the connector 13. The outer portion of the connector 11 is a hexagonal prism, similar to a hexagonal nut, which can be easily loosened and tightened. It can also be other shapes. It is a relatively mature technology and will not be described in detail here. A sealing ring 12 is bonded to the inner wall of the connector 11, and a sealing groove 14 with an interference fit with the sealing ring 12 is provided on the peripheral side of the connector 13. The sealing ring 12 and the sealing groove 14 can be one group or two groups, etc., to ensure the sealing effect during connection;

[0037] Among them, for the liquid storage tank 3, a liquid adding tube 10 is installed on one side of its top end, which can facilitate the addition of liquid, and a sealing plug can be plugged or threaded at the top end to facilitate the sealing operation. A motor 9 of a mixing assembly is installed in the middle of the liquid storage tank 3. The motor 9 is assembled on the liquid storage tank 3 for cleaning liquid, but not assembled on the liquid storage tank 3 for water. A rotating shaft 16 is fixedly installed on the output end of the motor 9 through a coupling. The rotating shaft 16 passes through the liquid storage tank 3 and extends to the inside where stirring rods 15 are equidistantly welded, which can also be blades, etc., which can facilitate the mixing and stirring of the cleaning liquid in the liquid storage tank 3 to ensure uniform distribution, so as to facilitate subsequent extraction and cleaning.

[0038] See also Figure 1-Figure 9 In order to ensure the cleaning effect and to facilitate drying of the inside of the pipeline without affecting the subsequent use, the end of the drainage pipe 8 close to the pipeline of the milk tea machine body 1 is connected to the inflation pipe 28 of the auxiliary inflation mechanism, which runs through the drainage pipe 8 and extends to the inside through a rotary joint 36 (a relatively mature technology, which will not be described in detail here) to install an aeration head 31 (made of porous materials, such as ceramics, plastics or metals, or other devices that can generate small bubbles, which is a relatively mature technology, which will not be described in detail here), and the aeration holes 38 are equidistantly inclined on the side of the aeration head 31, which can generate thrust with the airflow ejected from the aeration holes 38 after the compressed gas is introduced, and can carry the aeration head 31 It rotates on the rotary joint 36, and at the same time, an impeller 37 is welded on the side of the aeration head 31 below the aeration hole 38.

The inner wall of the top of the discharge pipe 8 is symmetrically welded with a vibration plate 39 close to one end of the pipeline. When the impeller 37 rotates, it contacts the vibration plate 39 and knocks it, so that the inner wall of the pipeline can be vibrated to assist in cleaning, and the top of the aeration head 31 The end of the aeration tube 28 can be bonded with a magnet 40, which can facilitate the adsorption of debris generated by the contact between the impeller 37 and the vibration plate 39, and the part rises with the air flow, while the rest is discharged through the drain pipe 8 when the subsequent cleaning liquid is discharged. The end of the inflation tube 28, the end away from the aeration head 31, is connected and fixed to the output end of the compressed air pump 6 (or other equipment), which can facilitate the compression of air and produce tiny bubbles in cooperation with the aeration head 31. When the bubbles rise in the water and finally burst, tiny turbulence and shock waves will be generated. These shock waves can effectively break the dirt layer on the tube wall, loosen it and fall off, and the presence of bubbles increases the fluidity and turbulence of the water, making the water flow more active.

For the collection box 5, a discharge pipe can be provided on its bottom end or side wall to facilitate the discharge of the filtered liquid. In order to ensure the stability of the filter screen 21 when in use, a mounting plate 18 of the mounting mechanism is welded on the inner side wall of the collection box 5, wherein the card plate 18 is provided with a card groove for convenient engagement and positioning of the mounting frame 17, and a sealing plate 19 is welded on the end of the mounting frame 17 away from the card plate 18, and a sealing plate 19 is welded on the outer wall thereof. A pulling groove is provided on the part, not shown in the figure, which can facilitate the pulling operation. A sealing groove adapted to the sealing plate 19 is provided on the side wall of the collection box 5. In order to ensure the sealing effect, a sealing gasket can be bonded to the inner peripheral side of the sealing groove, and the plug-in blocks 20 of the plug-in assembly are symmetrically welded at the top and bottom ends of the sealing plate 19.
