[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown:

[0024] A gas filling hose for compressed natural gas comprises a gas filling pipe 1.

[0025] In this embodiment: the existing announcement number: CN220506099U discloses a gas filling hose for compressed natural gas. This patent discloses a hose. The gas filling pipe 1 in this application document adopts the same technical means in this existing technology. This technical means will not be described here one by one. For details about the improvement of this existing technology, please refer to the technology disclosed below; in order to solve the technical problems existing in this existing technology, as disclosed in the background technology above, "when the device is not in use, its two ends are open, then the dust and impurities in the outside air are likely to enter the interior of the pipeline, and in the subsequent gas filling and transmission process, the cleanliness of the natural gas is affected." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problem, an A connector 2 and an exhaust nozzle 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In combination with the above content: it also includes an A connector 2, an exhaust nozzle 3, a B connector 4, a positioning ring 5, a baffle 6, a guide strip 7, a vent plate 8 and a spring 9 arranged on one side of the gas filling pipe 1. One end of the gas filling pipe 1 is fixedly connected to the inner surface of the A connector 2, and the inner surface of the A connector 2 is also fixedly installed with the exhaust nozzle 3, and a B connector 4 is also provided on one side of the exhaust nozzle 3. The B connector 4 is threadedly connected to the inner surface of the A connector 2, and the inner surface of the B connector 4 is also fixedly installed with a positioning ring 5 that is surface-fitted with the baffle 6, and the baffle 6 is also slidingly connected to the guide strip 7 fixedly installed on the surface of the vent plate 8. At the same time, the vent plate 8 is fixedly installed on the inner surface of the A connector 2, and a spring 9 is also sleeved on the outside of the guide strip 7, and one end of the spring 9 is fixedly connected to the surface of the vent plate 8, and the other end of the spring 9 is fixedly connected to the surface of the baffle 6.

[0029] In this embodiment: when natural gas needs to be refilled through the gas filling pipe 1, the A connector 2 and the B connector 4 can be rotated to connect. At this time, the exhaust nozzle 3 will gradually approach the baffle 6 and form a connection with the baffle 6. As the B connector 4 and the A connector 2 gradually rotate, the exhaust nozzle 3 will gradually push the baffle 6 and cause it to slide between the guide bar 7. At this time, the baffle 6 will separate from the positioning ring 5, and the baffle 6 compresses the spring 9 arranged on its inner side. At the same time, the guide bar 7 gradually extends into the interior of the exhaust nozzle 3. After a tight connection is formed between the A connector 2 and the B connector 4, natural gas can be refilled and transmitted to the B connector 4 and the gas filling pipe 1 on the side of the B connector 4 through the gas filling pipe 1 on the side of the exhaust nozzle 3, and the natural gas will be transmitted to the B connector through the through hole opened on the surface of the exhaust nozzle 3. The inside of the joint 4 is then transmitted through the gap between the positioning ring 5 and the baffle 6 to the position of the vent plate 8, and then transmitted to the gas filling pipe 1 through the hollow vent plate 8. When the gas filling work is completed, the A connector 2 and the B connector 4 can be separated. As the A connector 2 and the exhaust nozzle 3 gradually move away, the baffle 6 will slide between the guide bar 7 again under the reset action of the spring 9, and move toward the direction of the positioning ring 5 to form a closure with the positioning ring 5. At this time, the two ends of the B connector 4 are in a closed state, thereby ensuring the sealing inside the B connector 4, and ensuring that external dust and impurities will not enter the B connector 4 and the gas filling pipe 1 when they are not in use, thereby ensuring the cleanliness of the natural gas filling work and preventing impurities from entering the gas tank or during use.

[0030] It should be noted that the B connectors 4 are provided at both ends of the gas filling pipe 1 .

[0031] Going further:

[0032] In an optional embodiment, the exhaust nozzle 3 is cylindrical in shape, and circular through holes are opened at equal angles on the surface of the exhaust nozzle 3 .

[0033] In this embodiment: the cylindrical exhaust nozzle 3 can form a connection between the baffle 6 and push the baffle 6 when the A connector 2 and the B connector 4 are closed, and can also transmit gas to the inside of the B connector 4 and the gas filling pipe 1 connected to one side of the B connector 4 through the through hole opened on its surface.

[0034] Going further:

[0035] In an optional embodiment, the positioning ring 5 is in the shape of a circular ring, and the surface of the positioning ring 5 close to the blocking piece 6 is an inclined surface.

[0036] In this embodiment, the annular positioning ring 5 can stabilize the baffle 6 under the action of the spring 9, so that it can effectively block the opening of the B connector 4, thereby stably achieving dust prevention work for the gas pipe 1.

[0037] Going further:

[0038] In an optional embodiment, the blocking piece 6 is shaped like a truncated cone, and a circular through hole is formed on the surface of the blocking piece 6 .

[0039] In this embodiment, the frustum-shaped baffle 6 can form a stable closure with the positioning ring 5, and the through hole opened on the surface of the baffle 6 can also form a stable sliding relationship with the guide bar 7, thereby stably performing dust prevention work through the baffle 6.

[0040] Going further:

[0041] In an optional embodiment, the axes of the guide bar 7 and the B connector 4 are on the same straight line.

[0042] In this embodiment: the guide strip 7 arranged on the same axis as the B connector 4 can enable the baffle 6 to slide smoothly along its surface, and thus can ensure that the baffle 6 can be separated from the positioning ring 5 under the push of the exhaust nozzle 3 when a closure is formed between the A connector 2 and the B connector 4.

[0043] Going further:

[0044] In an optional embodiment, through holes are formed on the surface of the vent plate 8 at equal angles.

[0045] In this embodiment, the through holes formed on the surface of the vent sheet 8 enable natural gas to be smoothly injected into the gas filling pipe 1 through the A connector 2 and stably transported through the gas filling pipe 1. Furthermore, the vent sheet 8 can provide effective support for the spring 9 under the stability of the vent sheet 8, thereby providing basic conditions for the movement of the baffle 6.

[0046] The working principle and usage process of the present invention: When it is necessary to refuel natural gas through the gas filling pipe 1, the A connector 2 and the B connector 4 can be rotated to connect. At this time, the exhaust nozzle 3 will gradually approach the baffle 6 and form a connection with the baffle 6. As the B connector 4 and the A connector 2 gradually rotate, the exhaust nozzle 3 will gradually push the baffle 6 and cause it to slide between the baffle 6 and the guide bar 7. At this time, the baffle 6 will separate from the positioning ring 5, and the baffle 6 compresses the spring 9 arranged on its inner side. At the same time, the guide bar 7 gradually extends into the interior of the exhaust nozzle 3. After a tight connection is formed between the A connector 2 and the B connector 4, natural gas can be refueled and transmitted to the B connector 4 and the gas pipe 1 on the side of the B connector 4 through the gas filling pipe 1 on one side of the exhaust nozzle 3, and the natural gas will pass through the through hole opened on the surface of the exhaust nozzle 3. It is transmitted to the inside of the B connector 4, and then transmitted to the position of the vent plate 8 through the gap between the positioning ring 5 and the baffle 6, and then transmitted to the gas filling pipe 1 through the hollow vent plate 8. When the gas filling work is completed, the A connector 2 and the B connector 4 can be separated. As the A connector 2 and the exhaust nozzle 3 gradually move away, the baffle 6 will slide between the guide bar 7 again under the reset action of the spring 9, and move toward the direction of the positioning ring 5 to form a closure with the positioning ring 5. At this time, the two ends of the B connector 4 are in a closed state, thereby ensuring the sealing inside the B connector 4, and ensuring that external dust and impurities will not enter the B connector 4 and the gas filling pipe 1 when they are not in use, thereby ensuring the cleanliness of the natural gas filling work and preventing impurities from entering the gas tank or during use.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
