[0018] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0019] Figure 2 This is a cross-sectional view of the ejector tube structure and the furnace plate structure of this utility model. Detailed Implementation

[0020] like Figures 1-2 The swirl mixing gas furnace shown includes an ejector tube structure and a furnace plate structure. The furnace plate structure includes an upper furnace plate 1 and a lower furnace plate 8. The upper furnace plate 1 is housed in the lower furnace plate 8, and the upper furnace plate 1 serves as the upper end face of the furnace plate structure for flameout.

[0021] The surface of the upper furnace tray 1 is provided with a hole groove 12, which is arrayed along the center of the upper furnace tray 1, preferably 8, and each hole groove 12 is connected with a rotary cutting blade 13, which is inclined downward, and the gas is transported upward from the injection pipe structure, and the rotary cutting blade 13 at the bottom of the upper furnace tray 1 forms a rotating gas flow upward from the hole groove 12.

[0022] Referring to Figure 1 and Figure 2 , the rotary cutting blade 13 is the cutting residue in the hole machining of the hole groove 12, and the rotary cutting blade 13 has a connecting edge with the hole groove 12, which is folded downward by an angle A to form, and the angle A is between 25°-40°, preferably 30°. The rotary cutting blade 13 is a right trapezoidal structure, and the other corners of the rotary cutting blade 13 except the right angle are circular arc transition structures, and the long side of the right angle is the connecting edge of the rotary cutting blade 13 and the hole groove 12. This structure is easier to process, and can keep the stability of the angle A, and has better contact blocking effect with the gas flow, and can efficiently produce the rotating flow effect.

[0023] On the basis of the design of the rotary cutting blade 13, the injection pipe structure and the furnace tray structure of the embodiment also have the following designs:

[0024] Referring to Figure 2 , the inner wall of the furnace tray 8 and the upper furnace tray 1 surround a speed reduction chamber 82, which is a structure of wide at the top and narrow at the bottom, the inner wall of the speed reduction chamber 82 is a bevel structure, the bottom inner diameter of the speed reduction chamber 82 is between 10mm-20mm, preferably 15mm, the top inner diameter of the speed reduction chamber 82 is between 20mm-30mm, preferably 25mm, and the longitudinal depth of the speed reduction chamber 82 is between 4mm-6mm, preferably 5mm.

[0025] Continuing to refer to Figure 2 , the injection pipe structure includes an upper injection pipe 5 and a lower injection pipe 2, the inner diameter of the lower injection pipe 2 is larger than that of the upper injection pipe 5, the bottom of the lower injection pipe 2 is provided with a gas connection valve 6, and the peripheral wall of the lower injection pipe 2 is provided with an air inlet hole 7, and the butt joint of the upper injection pipe 5 and the lower furnace tray 8 is provided with an expanding chamber 51, which is a structure of wide at the top and narrow at the bottom.

[0026] The size of the air inlet hole 7 is between 4mm-6mm, preferably 5mm, the inner diameter of the lower injection pipe 2 is between 7mm-9mm, preferably 8mm, the inner diameter of the upper injection pipe 5 is between 5mm-7mm, preferably 6mm, and the overall length of the upper injection pipe 5 and the lower injection pipe 2 in the assembled state is between 30mm-40mm, preferably 35.5mm.

[0027] Referring to Figure 2As shown, the gas enters the lower injection pipe 2 from the bottom gas connection valve 6, and the air enters the lower injection pipe 2 from the air inlet hole 7 to mix. When entering, due to the increase in space, a first-stage airflow deceleration effect is formed, and the mixed gas continues to go upwards, passes through the flared cavity 51 and the slow-speed cavity 82, and under the structure of the upper wide and lower narrow, a second-stage airflow deceleration effect is formed, and continues to go upwards and impact the swirl vane 13 to generate resistance reflection, forming a third-stage airflow deceleration effect. After the mixed gas passes through the three deceleration effects under the action of the specially sized injection pipe structure and the furnace plate structure, the mixing time is prolonged, and the mixed gas continues to cooperate with the swirl vane 13 to form a rotating airflow upwards, further improving the sufficiency of the mixing, and avoiding the phenomenon of off-flame to the maximum extent.

[0028] On the basis of the above, the support structure is also improved, and the traditional support structure is shown in the figure, and can also refer to the utility model patent CN214406163U applied by the applicant in 2021. The bottom of the support 4 is hinged on the connecting piece 3 installed on the injection pipe structure, and the support 4 can rotate along the hinge shaft and has at least two states, an unfolded state and a storage state. In the unfolded state, the top of the support 4 is rotated above the furnace plate structure as a platform for supporting the pot. The main improvement of the embodiment is that the longitudinal distance between the top of the support 4 and the top of the furnace plate structure is between 18mm-25mm in the unfolded state, and is preferably 21mm. Referring to Figure 1 and Figure 2 As shown, the upper edge 81 of the lower furnace plate 8 is higher than the upper furnace plate by a distance, and the longitudinal distance between the top of the support 4 and the top of the furnace plate structure is the distance between the top of the support 4 and the upper edge 81 of the lower furnace plate 8. The upper edge 81 can guide the rotating airflow to a certain extent to ensure the stable upward movement of the rotating airflow (the upper edge 81 has a certain height for wind protection, protects the flame of the upper furnace plate 1, and has a certain wind resistance). By limiting the longitudinal distance between the top of the support 4 and the furnace plate structure, that is, limiting the distance between the pot and the furnace plate structure when in use, the combustion effect can be improved by reasonably configuring the distance.

[0029] The utility model has been described above in conjunction with the drawings, and obviously the specific implementation of the utility model is not limited by the above method, as long as various improvements are made by adopting the method concept and technical scheme of the utility model, or direct application in other fields without improvement, which all fall within the protection scope of the utility model.
