Fig.14 The diagram shows that the regulating component is in a state where the pipeline is fully connected. The working principle of the regulating component 3 generally includes:
[0048] By operating the adjusting boss 333, the adjusting hole 332 of the adjusting block 33 can be misaligned with respect to the channel between the inlet 3121 of the upper cover 31 and the outlet 3222 of the lower cover 32, which can change the cross-sectional area of the liquid flowing through the adjusting hole 332, resulting in changing the cross-sectional area of the pipeline through which the adjusting liquid passes and changing the pressure in the pipeline, thereby ultimately changing the pressure of the liquid when it flows out of the outlet 3122 of the upper cover 31 and changing the speed of the ejected liquid.
[0049] See also Fig.12 When the adjustment indicator 334 is aligned with the first groove from the left of the scale 3113, the adjustment hole 332 is not completely located in the channel between the inlet 3121 of the upper cover 31 and the outlet 3222 of the lower cover 32, that is, the adjustment hole 332 is completely not aligned with the channel between the inlet 3121 of the upper cover 31 and the outlet 3222 of the lower cover 32.

[0050] See also Fig.13 When the adjustment indicator 334 is aligned with the second groove from the left of the scale 3113, a portion of the adjustment hole 332 is located in the channel between the inlet 3121 of the upper cover 31 and the outlet 3222 of the lower cover 32, that is, a portion of the adjustment hole 332 is aligned with the channel between the inlet 3121 of the upper cover 31 and the outlet 3222 of the lower cover 32.

[0051] See also Fig.14 When the adjustment indicator 334 is aligned with the third groove from the left of the scale 3113, the adjustment hole 332 is completely located in the channel between the inlet 3121 of the upper cover 31 and the outlet 3222 of the lower cover 32, that is, the entirety of the adjustment hole 332 is aligned with the channel between the inlet 3121 of the upper cover 31 and the outlet 3222 of the lower cover 32. At this time, the liquid can flow through the entirety of the adjustment hole 332, and the pipeline is in a fully conductive state.
