[0016] Referring to Figure 1A constant-pressure, flow-regulating burner injector includes an injector housing 1, with a spring 2 installed inside. The injector housing 1 also has an installation groove 3 for heavy oil flow. The front end of the installation groove 3 is an outlet 4 through which the heavy oil, after being filtered and atomized, is sprayed out. A hollow connecting post 5, a swirling fluid 6, and an atomizing plate 7 are installed within the installation groove 3. The output port of the atomizing plate 7 corresponds to the outlet 4, allowing the heavy oil to be atomized and sprayed out through the outlet 4. The swirling fluid 6 is hollow in the middle and communicates with the middle of the connecting post 5, allowing the heavy oil to flow back through the middle of the swirling fluid 6. An installation post 8 is located at the top of the injector housing 1, with an overflow hole 9 in the middle that communicates with the installation groove 3, allowing the heavy oil to be discharged through the overflow hole 9. The overflow hole 9 is used to discharge pressure and heavy oil, relieving pressure within the injector. The bottom of the oil nozzle housing 1 is provided with a handle 10. A filter element 11 is installed in the middle of the handle 10 and communicates with the mounting groove 3. The filter element 11 is used to filter heavy oil. The bottom of the handle 10 is provided with an oil inlet 12 for inputting heavy oil.

[0017] In one embodiment of this utility model, a circular groove 14 is provided in the middle of both sides of the swirling fluid 6. A protrusion is provided in the circular groove 14, and the protrusion abuts against the atomizing plate 7. The heavy oil rotates in the circular groove 14 and flows through the protrusion into the atomizing plate 7.
