meanwhile, when the flame or heat moves in the combustion heat conduction cylinder in a rotating state, the flame or heat can move on the surface of the combustion heat conduction cylinder in a manner of being more attached to the surface of the combustion heat conduction cylinder under the action of centrifugal force, so that not only is the movement path long and the heat conduction effect good, but also the movement direction and the movement path of the flame or heat are regular in the rotating movement process, and the pressure fluctuation acting on the inner wall of the combustion heat conduction cylinder is small, so that the noise is reduced, and the silencing effect is achieved; in the prior art, flame or heat entering the combustion heat conduction cylinder has a plurality of irregular motions, and pressure fluctuation formed by collision of the flame or heat and the inner wall of the combustion heat conduction cylinder is large, so that noise is large, but the noise-eliminating and silencing effect is achieved through the rotary motion, the noise is reduced by 10dB-15dB, user experience is improved, and the application range of the parking heater is expanded;

in addition, when the combustion-supporting gas continuously and spirally rotates in the mixed combustion cavity, the combustion-supporting gas can carry the fuel to change a motion path and continuously rotate along with the rotation, and the atomization effect of the atomization net in the prior art can be achieved, so that the fuel atomization effect can be achieved without adding the atomization net, the structure is simplified, and the production and installation cost is reduced; meanwhile, the atomization net can be continuously reused and is matched with the rotational flow air outlet for use, so that a better atomization effect can be achieved, and the mixing speed of combustion air and fuel is further improved.

The analysis and the test are combined to obtain that the rotational flow air outlet can effectively improve the thermal efficiency of the heater by 15 to 25 percent, belongs to the prominent technical improvement in the field and overcomes the technical problem in the prior art.

In the prior art, as long as the air outlet of the distributor is a direct-current air outlet, no matter whether the cyclone device is additionally arranged at the air inlet of the distributor, the effect of generating rotating airflow cannot be realized or the airflow rotating effect is weak, and even if the cyclone device is not arranged, the airflow rotating effect can be realized due to the arrangement of the cyclone air outlet; in order to further improve the effect of airflow rotation, in this embodiment, the cyclone device 5 is correspondingly disposed at the air inlet of the distributor body 11, the direction of the rotating airflow formed by the cyclone device 5 is the same as the direction of the rotating airflow formed by the cyclone air outlet, and at this time, the cyclone device 5 is used in cooperation with the cyclone air outlet, so that the generated airflow rotation effect is better.

The cyclone air outlet is obliquely arranged on the distributor air guide sleeve 13 (the upper direction does not refer to the up-down direction here), and the extension line of the air outlet direction of the cyclone air outlet on the cross section of the distributor air guide sleeve 13 does not intersect with the center of the distributor air guide sleeve 13. Referring to fig. 3, F represents the wind outlet direction of the swirling outlet on the cross section of the distributor dome 13, the extension line of the straight-flow outlet does not intersect with the center of the distributor dome 13, and the extension line of the outlet direction of the dc outlet in the prior art shown in fig. 18 intersects with the center of the distributor dome 13, so that the outlet direction is radially discharged along the surface of the distributor when the outlet direction intersects with the center of the distributor dome 13, but the outlet direction is not radially discharged along the surface of the distributor as shown in fig. 18 in the present embodiment, because the extension line of the air outlet direction of the rotational flow air outlet does not intersect with the center of the distributor dome 13, therefore, the air outlet direction of the cyclone air outlet generates a tangential movement trend at this time, the rotating airflow shown in figure 3 is formed in the mixed combustion chamber, the rotating air flow is discharged by the air flow pressure toward the outlet, thereby creating a spiral path of motion as shown in fig. 1. In this embodiment, the air outlet direction of the swirling air outlet is not radially arranged along the surface of the distributor dome, and does not intersect with the center of the distributor dome 13, so that a swirling included angle for generating a rotating airflow is formed between the air outlet direction of the swirling air outlet and the tangential direction when viewed from the cross section of the distributor dome, the swirling included angle is less than 90 degrees and not less than 0 degree, and when the swirling included angle is 15 degrees to 45 degrees, a relatively stable rotating airflow can be generated, and the processing is also convenient.

The cyclone air outlet is an inclined air outlet slot which is obliquely arranged on the distributor air guide sleeve 13, in this embodiment, the inclined air outlet slot is a rectangular slot, as shown in fig. 2 and fig. 3, the length direction of the inclined air outlet slot extends along the axial direction of the distributor air guide sleeve 13 to form a long strip structure, and the inclined air outlet slots are uniformly arranged and have the same length.

In the prior art, since the fuel enters the mixing combustion chamber 14 from one position and gradually diffuses in the mixing combustion chamber 14, the concentration distribution of the fuel at each position in the mixing combustion chamber 14 is not uniform, and the combustion-supporting gas is discharged into the mixing combustion chamber 14 in a straight-flow manner, which results in different concentrations of the combustible mixture at each position in the mixing combustion chamber and poorer mixing uniformity, so that the opening size, the distance and the length of the straight-flow air outlets arranged on the distributor air guide sleeve 13 in the prior art are different (see fig. 17 and 18 for the arrangement effect of the straight-flow air outlets), so as to adjust the combustion-supporting air, so that the combustion-supporting air entering each position in the mixing combustion chamber 14 is different, so as to make the combustible mixture at each position after mixing as uniform as possible, but at this time, the processing of the distributor air guide sleeve 13, The manufacturing cost is relatively high, the processing difficulty is high, the error is high, the design and the actual use are deviated possibly, and the ideal use effect cannot be achieved; in the invention, even if the concentration distribution of the fuel in the mixed combustion chamber 14 is not uniform, the combustion-supporting gas enters the mixed combustion chamber 14 in a spiral rotating state and then can drive the fuel to rotate, so that the formed combustible mixed gas rotates, and the purpose of uniform mixing can be achieved in the rotating process of the combustible mixed gas in the mixed combustion chamber 14. Of course, the cyclone air outlet can be provided with openings with different widths, lengths and intervals according to actual needs.

In the embodiment, the cyclone distributor 1 is integrally formed and processed by powder metallurgy, so that the processing is convenient, the difficulty is reduced, the batch production can be realized, and the processing efficiency is improved; of course, the cyclone distributor 1 may also be machined, and any machining method is within the scope of the present invention as long as the cyclone air outlet structure of the present invention is adopted.
