[0036] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0037] Reference Figures 1 to 2 As shown, this embodiment of the utility model provides an air guiding mechanism.

[0038] The air guide mechanism is used in gas heaters, see reference. Figure 3 and Figure 4 As shown, the gas heater is equipped with an air outlet 10, and an air outlet 11 is provided at the front end of the air outlet 10.

[0039] The air guiding mechanism includes an outer cylinder 100, a mounting bracket 200, and multiple air guiding plates 300.

[0040] The outer cylinder 100 has an air guide 110 that runs through the front and rear directions in the middle. When the outer cylinder 100 is installed at the front end of the air outlet 10 of the gas heater, the air guide 110 is directly opposite the air outlet 11 of the air outlet 10.

[0041] The mounting bracket 200 is installed in the air duct 110 of the outer cylinder 100. The mounting bracket 200 is hinged to the outer cylinder 100. The rotation axis of the mounting bracket 200 can be set according to requirements; for example, the mounting bracket 200 can rotate about a horizontal axis or about a vertical axis. Taking the plane where the air outlet 11 of the air outlet duct 10 is located as the reference plane, the rotation axis of the mounting bracket 200 can be any straight line parallel to the reference plane. In this embodiment, the mounting bracket 200 rotates about an axis extending in the left-right direction.

[0042] The mounting bracket 200 connects to multiple air guide plates 300. The mounting bracket 200 drives the multiple air guide plates 300 to rotate. The multiple air guide plates 300 are located in the air guide port 110 so that the multiple air guide plates 300 can guide the hot air blown out of the air guide port 110.

[0043] The outer cylinder 100 of the air guide mechanism is installed on the air outlet duct 10 of the gas heater. Then, by rotating the mounting bracket 200, the angle of the mounting bracket 200 relative to the outer cylinder 100 is changed, so that the multiple air guide plates 300 guide the direction of the hot air blown out of the air outlet 11 of the air outlet duct 10, thereby changing the air outlet direction of the gas heater. This eliminates the need to move the gas heater, making the adjustment of the air outlet direction of the gas heater more convenient.

[0044] In some embodiments, refer to Figure 1 and Figure 2 As shown, multiple air guide plates 300 are parallel to each other.

[0045] Multiple parallel air guide plates 300 guide the hot air blown out of the air guide 110 in a unified manner, ensuring that the hot air blown out of the air guide 110 is delivered to a greater distance.

[0046] In some embodiments, the outer cylinder 100, the mounting bracket 200, and the plurality of air guide plates 300 are all made of metal components.

[0047] The hot air blown out by the gas heater is at a high temperature, and the metal components can work in high-temperature environments, ensuring that the shape of the air guide plate 300 is not affected by temperature and thus ensuring the air guiding effect.

[0048] In some embodiments, refer to Figure 1 and Figure 2 As shown, the outer cylinder 100 is a cylindrical shape extending from front to back. The air guide 110 is a channel in the middle of the outer cylinder 100. The air guide 110 is a circular hole. The mounting frame 200 is a circular ring component. The mounting frame 200 is set in the air guide 110 of the outer cylinder 100. The middle part of the mounting frame 200 is provided with a circular inner hole 210. Multiple air guide plates 300 are set in the inner hole 210 of the mounting frame 200. The multiple air guide plates 300 are distributed at intervals from top to bottom.

[0049] The outer cylinder 100 and mounting bracket 200 are set to match the shape of the existing gas heater air outlet duct 10, so that the outer cylinder 100 can be installed more compactly on the air outlet duct 10, and the shape of the mounting bracket 200 matches the shape of the air outlet 11, ensuring that the multiple air guide plates 300 can form an air guiding effect in front of the air outlet 11.

[0050] In some embodiments, refer to Figure 1 and Figure 2 As shown, one of the air guide plates 300 is provided with a lever 310, which is located at the front end of the air guide plate 300 and extends forward.

[0051] When it is necessary to adjust the angle of the mounting bracket 200 relative to the outer cylinder 100, the user can swing the lever 310 to make multiple air guide plates 300 turn simultaneously.

[0052] In some embodiments, refer to Figure 1 and Figure 2 As shown, the rear side of the outer cylinder 100 is connected to the front end of the air outlet duct 10, and the front side of the outer cylinder 100 is hinged to the mounting bracket 200.

[0053] The air outlet duct 10 and the mounting bracket 200 are separated by the length of the outer cylinder 100 in the front and rear directions, which ensures the rotation angle of the mounting bracket 200 and reduces the interference of the air outlet duct 10 on the mounting bracket 200.

[0054] In some embodiments, refer to Figure 1 and Figure 2 As shown, the outer wall of the outer cylinder 100 is provided with multiple through holes, and the air guide mechanism is provided with multiple fasteners. The multiple fasteners are provided one-to-one in the multiple through holes of the outer cylinder 100, and the multiple fasteners are used to detachably connect the air outlet duct 10.

[0055] Fasteners are used to connect to the air outlet duct 10 through the through hole of the outer cylinder 100, making the installation and disassembly of the air guide mechanism more convenient.

[0056] In some embodiments, refer to Figure 1 and Figure 2 As shown, the mounting bracket 200 rotates about an axis extending in the left-right direction.

[0057] Existing gas heaters typically blow hot air forward from the air outlet duct 10. By adjusting the tilt angle of the air outlet duct 10, the distance from which the hot air is blown can be changed to ensure that the hot air can be blown to a farther location. Therefore, by setting the mounting bracket 200 to rotate around the left and right axis, it is not necessary to adjust the tilt angle of the air outlet duct 10. The distance from which the hot air is blown out by the gas heater can be adjusted by having multiple air guide plates 300 swing up or down with the mounting bracket 200.

[0058] Reference Figure 3 and Figure 7 As shown in the figure, this utility model embodiment also provides a gas heater.

[0059] The gas heater includes the air guiding mechanism as described in the above embodiments. The gas heater also includes an air outlet 10, with an air outlet 11 provided at the front end of the air outlet 10. The air guiding mechanism is detachably installed at the front end of the air outlet 10.

[0060] In some embodiments, refer to Figure 3 and Figure 4 As shown, the air outlet duct 10 gradually tilts upwards from back to front.

[0061] Existing gas heaters typically blow hot air forward through their air outlet duct 10. The air outlet duct 10 is tilted upwards, which helps to deliver the hot air to a more distant location.

[0062] Reference Figures 4 to 7As shown, the gas heater also includes a burner assembly 400, a front cover 430, a rear cover 440, and an ejector tube 450.

[0063] The burner assembly 400 is provided with a plurality of first annular plates 410 and a plurality of second annular plates 420. Each first annular plate 410 is provided with a plurality of pleats 411 arranged sequentially along the circumference. The pleats 411 make the first annular plate 410 wavy. The plurality of first annular plates 410 and the plurality of second annular plates 420 are arranged alternately in the front-back direction. A first annular plate 410 is provided between every two second annular plates 420. The pleats 411 of the first annular plate 410 form a plurality of ventilation holes on the outer periphery of the burner assembly 400.

[0064] The front cover 430 is located on the front side of the burner assembly 400. A forward-protruding cone-shaped section is provided in the center of the front cover 430. (Refer to...) Figure 7 As shown, the gas in the middle of the burner assembly 400 is blown toward the cone and blocked by the cone. The cone protrudes forward, and the gas blocked by the cone flows backward along the inclined side wall of the cone, which helps the gas to spread evenly to the periphery of the burner assembly 400.

[0065] The rear cover 440 is located on the rear side of the burner assembly 400. The middle of the rear cover 440 is provided with an air inlet 441 that runs through the front and rear directions. The ejector tube 450 is connected to the air inlet 441 of the rear cover 440 so that the ejector tube 450 can spray gas into the burner assembly 400 through the air inlet 441.

[0066] The burner assembly 400 helps the gas to diffuse evenly to the outer periphery along the gap formed between the first annular plate 410 folds 411 and the second annular plate 420, which helps to form a uniform combustion effect around the burner assembly 400 and improve the combustion efficiency of the burner assembly 400.

[0067] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
