Description

Technical Field

[0001] The utility model relates to the technical field of flow switches, and more specifically, to a flow switch capable of cleaning a probe. Background Art

[0002] Flow switches are mainly installed online or plug-in in water, gas, oil and other medium pipelines to monitor the water flow rate in the water system. When the flow switch is in use, it is installed on the pipeline, and the detection probe at the bottom is inserted into the pipeline. Since there are many impurities inside the pipeline, it will affect the detection efficiency of the detection probe. However, when the existing flow switch is in use, when it encounters a small pipeline, it is easy to cause the detection probe to be squeezed and damaged, which will affect the normal use of the detection probe.

[0003] The utility model patent with patent publication number CN216050089U discloses a highly sensitive thermal flow switch. The advantage of this structure is that by setting up two heating sensors, the thermal flow switch body can be installed without paying attention to the direction of the heating sensors, and the flow rate can be detected without affecting the detection effect, thereby improving the sensitivity of the thermal flow switch body detection. At the same time, the anti-collision pad can prevent the probe rod from being damaged due to collision, and prevent the probe rod from being squeezed when the length of the probe rod is greater than the pipeline depth, thereby causing damage, thereby playing a protective buffering role.

[0004] However, in actual use, although this structure can protect the probe rod, since the probe is in direct contact with the water inside the pipe, and the water contains more impurities, the impurities are easily adsorbed on the probe surface, which will cause the accuracy of the probe detection to decrease.
