[0020] The following will be combined with the accompanying 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.

[0021] Reference Figure 1-Figure 3The tire pressure flash warning device includes a transparent shell 1, a flash lamp 2 is installed on the top of the inner part of the transparent shell 1, and a circuit board 3 is placed on the upper inner side of the transparent shell 1. A scattered light area 101 is provided on the outer side of the transparent shell 1. The scattered light area 101 is a truncated cone structure. When the flash lamp 2 flashes, it can perform scattered light operation through the scattered light area 101, so that the scattered light covers a large range, which is convenient for people to observe and know. A battery pack frame 4 is placed on the inner side of the transparent shell 1, and the bottom end of the battery pack frame 4 is connected to an elastic sheet 5. A fixed frame 6 is installed on the inner side of the transparent shell 1, and the bottom of the fixed frame 6 There is a rubber ring 8 in contact with the fixing frame 6. A through hole is provided on the inner side of the fixing frame 6 to match the rubber ring 8, so that a part of the rubber ring 8 can pass through the through hole at the fixing frame 6 and push the elastic sheet 5 to disconnect it from the connecting sheet 12. Only when the tire pressure is less than 2.2 kg, the rubber ring 8 is reset, the elastic sheet 5 is connected to the connecting sheet 12, so that the circuit is turned on and the flashlight 2 can perform a flash alarm. The bottom end of the rubber ring 8 is connected to the top block 7, the inner side of the transparent shell 1 is connected to the valve nut area 10, and the inner side of the valve nut area 10 is provided with a valve core 11, and between the valve core 11 and the top block 7 is The abutment setting is different, and the air pressure of the valve core 11 entering the rubber ring 8 is different. Therefore, when the tire pressure is at a normal value, after the valve core 11 abuts against the top block 7, the air pressure entering the rubber ring 8 is larger, which can support the elastic sheet 5 so that it does not contact the connecting piece 12, and the flash light 2 is in a disconnected state. Otherwise, on the contrary, one side of the fixed frame 6 is connected with the connecting piece 12, and the inner side of the top block 7 is a hollow structure, and is connected to the inner side of the rubber ring 8. The airflow discharged after the valve core 11 is squeezed can enter the inner side of the rubber ring 8 through the top block 7, making the rubber ring 8 convex, which can support the elastic sheet 5. The sheet 5 is pushed to disconnect it from the connecting sheet 12. On the contrary, the connecting sheet 12 is electrically connected to the elastic sheet 5, and the connecting sheet 12 is connected to the circuit board 3 through a wire. The connecting sheet 12 is a circular ring structure, and the connecting sheet 12 is connected to the positive pole of the circuit board 3. The battery pack frame 4 is connected to the negative pole of the circuit board 3, so that after the connecting sheet 12 connected to the positive pole of the circuit board 3 contacts the elastic sheet 5, the flashlight 2 is in a passage state and can perform a flash alarm. A sealing gasket 9 is placed on the inner side of the transparent shell 1. The sealing gasket 9 mainly serves to seal the device when it is connected to the valve nut area 10.

[0022] Working principle: When in use, the staff first threadedly connects the device to the valve nut area 10. After connection, the top block 7 and the valve core 11 are in abutment. When the tire is at normal tire pressure, the gas passes through the top block 7 and enters the rubber ring 8, causing it to push the elastic sheet 5. The elastic sheet 5 and the connecting sheet 12 are disconnected, so that the device does not flash. Only when the tire pressure is less than 2.2 kg, the airflow pressure of the airflow at the valve core 11 entering the rubber ring 8 decreases, the rubber ring 8 resets, and the elastic sheet 5 is connected to the connecting sheet 12, so that the circuit is turned on, and the flash light 2 can perform a flash alarm, thereby completing the flash alarm work in real time according to the tire pressure situation (it should be noted that the specific model specifications of the electrical parts involved in this scheme need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail).

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
