In one embodiment, the joint comprises at least two mounting rings.
In one embodiment, the four coatings are two red and two white in color.
In one embodiment, the rear part of the main cylinder body is provided with a viewing hole and a glass window which are symmetrical with the front part, and the rear panel of the impeller is provided with a coating which is symmetrical with the front panel.
The invention has the advantages and beneficial effects that: the invention is arranged at the foremost end of the household gas pipe when in use. The gas pipeline is slightly broken, when small leakage is generated, the gas impacts the impeller to enable the impeller to slowly rotate, the color of the coating can be continuously switched through the observation hole, namely the color is a flickering effect, and the slight leakage of the gas pipeline is prompted so as to be timely disposed.

Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "disposed" on another element, it can be directly disposed or attached to the other element or intervening elements may also be present. The terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, but do not indicate or imply that the referenced device or element must have a particular orientation, be constructed in a particular orientation, and be operated.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Example 1
As shown in fig. 1-4, a household gas pipeline leakage protection device comprises a main cylinder 1 and connectors 2 arranged at two ends of the main cylinder 1, wherein an impeller 3 is arranged in the main cylinder 1, an observation hole 4 is arranged at the front part of the main cylinder 1, a glass window 5 is arranged in the observation hole 4, the impeller 3 comprises a front panel 6, a rear panel 7 and a plurality of fan blades 8 arranged between the front panel 6 and the rear panel 7, the fan blades 8 are arc-shaped and are distributed in a divergent annular shape, a central hole 9 penetrating through the front panel 6, the fan blades 8 and the rear panel 7 is also arranged, a rotating shaft 10 is arranged at the axis of the main cylinder 1, the central hole 9 of the impeller 3 is sleeved on the rotating shaft 10, four 90-degree fan-shaped coatings 11 are arranged on the front panel 6, the opposite coatings 11 are the same in color, the adjacent coatings 11 are different in color, the front panel 6 faces the front part of the main cylinder 1, the joint 2 is connected with the main cylinder 1 in a hollow mode, the hollow part of the joint faces the lower portion of the impeller 3, an indicating arrow 12 is further arranged on the front portion of the main cylinder 1, and the direction of the indicating arrow 12 is back to the side, where the circle center of the fan blade 8 on the lower portion of the impeller 3 is located. Indicating the correct flow direction of the gas in use.
The joint comprises three mounting rings 13 for improving the reliability of connection with the gas pipe.
The four coatings 11 are two red and two white in color, two red being opposite and two white being opposite.
The rear part of the main cylinder body can be provided with an observation hole and a glass window which are symmetrical with the front part, and the rear panel of the impeller is provided with a coating which is symmetrical with the front panel. So that both sides of the main cylinder can be observed.
When the gas burner is used, the gas burner is arranged at the foremost end of a household gas pipe, generally in a prominent position of a kitchen, and the arrow direction indicates the correct flow direction of gas. If the gas pipeline is normal, when generally using, the gas strikes impeller fast revolution, sees from the observation window, and the vision embodies the colour mixture of four coatings, is single colour, and the impeller stops when not using, also embodies no color change. When the gas turbine is not used, if the pipeline generates small leakage, the impeller is impacted by gas to rotate slowly, and the two colors are switched continuously visually, namely, a flicker effect is generated, so that people can find the two colors easily. Obviously, the invention only alarms the slight leakage of the gas pipe, if the large leakage occurs, people can easily find out through sound or smell, and if the large leakage occurs, people can also find out whether the impeller rotates.
The invention has simple structure, high stability and low cost, and is a pure mechanical part.
