DETAILED DESCRIPTION

[0020] 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.

[0021] The present invention provides a high-efficiency cooling needle barrel. Figure 1-4 As shown, the syringe comprises a syringe 1, a cooling pump 6, a circulation mechanism 11, an air inlet pipe 5, and an air outlet pipe 8. A spiral channel 13 is provided within the syringe 1, and an air inlet channel 15 and an air outlet channel 14 are provided on one side of the syringe 1. The air inlet channel 15 and the air outlet channel 14 are connected to the ends of the spiral channel 13, respectively. The cooling pump 6 is connected to the air outlet channel 14 and the air inlet channel 15, respectively, via the air outlet pipe 8 and the air inlet pipe 5. The circulation mechanism 11 is provided on the air outlet pipe 8.

[0022] It also includes a plurality of heat sinks 7 , which are arranged on the air outlet pipe 8 at equal intervals.

[0023] The circulation mechanism 11 includes a connecting seat 12, a branching guide seat 9, an electric valve 10, and two conduits 4. The branching guide seat 9 is arranged on the outlet pipe 8, and the connecting seat 12 is arranged on top of the branching guide seat 9. The electric valve 10 is arranged on top of the connecting seat 12, and the conduits 4 are arranged at the bottom of the connecting seat 12.

[0024] The circulation mechanism 11 also includes a connecting seat 3, an air jet connector 2, and two auxiliary conduits 21. The air jet connector 2 is mounted on the air inlet pipe 5, and the connecting seat 3 is connected to the conduit 4. The air jet connector 2 is connected to the connecting seat 3 through the auxiliary conduits 21, and the air outlet of the air jet connector 2 is aligned with the length of the air inlet pipe 5.

[0025] The system further includes two valves 22 , which are respectively disposed in the air outlet channel 14 and the air inlet channel 15 .

[0026] The assembly also includes a guide rail 17, a slider 18, a baffle 19, a spring 20, and a paddle 16. The guide rail 17 is positioned on one side of the connecting base 3, and the slider 18 slides within the guide rail 17. The baffle 19 is flexibly mounted on the air inlet pipe 5, corresponding to the air outlet of the air jet connector 2 and connected to the slider 18. The paddle 16 is positioned on top of the slider 18 and contacts the guide rail 17. One end of the spring 20 is connected to the slider 18, and the other end is fixed to the connecting base 3.

[0027] Working principle: When in use, first connect the outlet channel 14 and the inlet channel 15 of the syringe to the inlet pipe 5 and the outlet pipe 8 on the cooling pump 6. Then the cooling pump 6 sends cold air from the inlet pipe 5 into the syringe 1. The cold air flows along the spiral channel 13 and flows into the branch guide seat 9. At the same time, the branch guide seat 9 is equipped with a temperature detection device. If the exhaust gas temperature is lower than the room temperature, it is sent to the cooling pump 6 for circulation. If it is higher than the ambient temperature, it is discharged through the electric valve 10 on the connecting seat 12.

[0028] At the same time, exhaust gas can be controlled to flow from connector 12 along conduit 4, connecting base 3, and auxiliary conduit 21 into jet connector 2. Jet connector 2 then forms an insulating layer on the surface of intake pipe 5. In this way, if the temperature of the circulated exhaust gas is lower than the ambient temperature, the exhaust gas will be sprayed onto intake pipe 5, preventing the unused gas in intake pipe 5 from heating up too quickly. At the same time, baffle 19 moves under the jet from jet connector 2, allowing paddle 16 to pry the heat sink 7, which was originally used for heat dissipation, thereby cleaning the heat sink 7.

[0029] In summary, the high-efficiency cooling syringe, through the cooperation of the syringe 1, cooling pump 6, circulation mechanism 11, air inlet pipe 5 and air outlet pipe 8, enables the present invention to dissipate heat from the entire syringe by feeding cold and warm gas into the syringe. At the same time, in order to prevent the temperature in some factories from being too low, thereby causing deformation of the syringe metal due to heat exchange, the present invention can also preheat the pipeline with the heated exhaust gas to reduce the situation where the temperature difference between the cooling gas and the ambient temperature is too large and the gas temperature rises too quickly.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
