[0039] Reference Figure 1-Figure 4 The symmetrical structure of the air nozzle comprises a long strip-shaped shell 1, a partition 2 is provided in the middle of the shell 1 along the height direction of the shell 1, and the inner cavity of the shell 1 is divided into a left cavity 3 and a right cavity 4 by the partition 2;

[0040] The left cavity 3 is provided with a left air inlet cavity 31 arranged along the length direction of the housing 1, and the left side of the housing 1 is provided with a left air inlet port 311 connected with the left air inlet cavity 31; the left air inlet cavity 31 is provided with a left air cavity outlet port 312 toward the top of the housing 1;

[0041] A first left air mixing chamber 32 is provided in the left chamber 3 and above the left air inlet chamber 31; a second left air mixing chamber 33 is provided in the left chamber 3 and below the left air inlet chamber 31;

[0042] A left air outlet channel 34 is provided between the side wall of the left air inlet chamber 31 and the inner wall of the housing 1 , and the left air outlet channel 34 is connected to the first left air mixing chamber 32 and the second left air mixing chamber 33 ;

[0043] The right cavity 4 is provided with a right air inlet cavity 41 arranged along the length direction of the housing 1, and the right side of the housing 1 is provided with a right air inlet port 411 connected with the right air inlet cavity 41; the right air inlet cavity 41 is provided with a right air cavity outlet port 412 toward the top of the housing 1;

[0044] A first right air mixing chamber 42 is provided in the right chamber 4 and above the right air inlet chamber 41; a second right air mixing chamber 43 is provided in the right chamber 4 and below the right air inlet chamber 41;

[0045] A right air outlet channel 44 is provided between the right air inlet chamber 41 and the inner wall of the housing 1 , and the right air outlet channel 44 is connected to the first right air mixing chamber 42 and the second right air mixing chamber 43 ;

[0046] An air outlet 11 communicating with the left chamber 3 and the right chamber 4 is provided on one side of the bottom of the housing 1 close to the second left air mixing chamber 33 and the second right air mixing chamber 43 .

[0047] In the present invention, the left air inlet 311 and the right air inlet 411 simultaneously take in air from both sides, which can improve the overall temperature uniformity of the air nozzle compared to the existing single-sided air inlet; wherein the partition 2 can effectively prevent the mixing of the fluids on both sides of the left cavity 3 and the right cavity 4, which causes the internal fluids of the air nozzle to interfere with each other, thereby avoiding uneven wind speed inside the air nozzle; the left cavity 3 and the right cavity 4 have the same working principle. Taking the left cavity 3 as an example, the left air cavity outlet 312 is arranged toward the top of the shell 1. When the hot fluid enters the left air inlet cavity 31 from the left air inlet 311, it is mixed for the first time in the first left air mixing cavity 32, and then flows to the second left air mixing cavity 3 through the left air outlet channel 34. 3, the temperature of the hot fluids is mutually transferred, and they flow out from the air outlet 11 after the temperature is uniform. In this process, since the left air inlet cavity 31 has no contact with the inner wall of the shell 1, the hot fluid enters the left air inlet cavity 31, so that a heat preservation layer is formed between the left air inlet cavity 31 and the outside of the air nozzle, thereby reducing the temperature loss of the air nozzle. Compared with the existing air nozzle structure with single-side air inlet, the hot air flows out of the air nozzle directly after entering the air cavity, resulting in a large temperature loss of the air nozzle. The utility model improves the air outlet method and sets a hot fluid mixing structure. Therefore, the air outlet speed and air outlet temperature between each point of the air outlet 11 are uniform, and the air outlet effect is good.

[0048] Furthermore, the cross-sectional area of ​​the left air inlet cavity 31 is gradually reduced from the left air inlet 311 side to the partition 2 side;

[0049] The cross-sectional area of ​​the right air inlet cavity 41 is gradually reduced from the right air inlet 411 side to the partition plate 2 side.

[0050] Taking the left chamber 3 as an example, when the hot fluid flows from the left air inlet 311 to the partition 2, the inner wall of the left air inlet chamber 31 generates resistance to the hot fluid, causing the hot fluid to lose kinetic energy, reduce the flow rate, and reduce the unit cross-sectional area of ​​the hot fluid, so that the speed of the hot fluid flowing out from each point of the left air chamber outlet 312 tends to be consistent, thereby improving the uniformity of the wind speed discharged to the first left mixing chamber 32.

[0051] Specifically, the bottom wall of the left air inlet cavity 31 is arranged parallel to the bottom wall of the housing 1; the bottom wall of the right air inlet cavity 41 is arranged parallel to the bottom wall of the housing 1;

[0052] The cross-sectional area of ​​the first left air mixing chamber 32 is gradually increased from the left air inlet 311 to the partition 2;

[0053] The cross-sectional area of ​​the first right air mixing chamber 42 is gradually increased from the right air inlet 411 to the partition plate 2 .

[0054] It is equivalent to that when the hot fluid enters the left air inlet chamber 31 and the right air inlet chamber 41, the resistance formed to the hot fluid is mainly caused by the inner wall of the left air inlet chamber 31 close to the first left mixing chamber 32 and the inner wall of the right air inlet chamber 41 close to the first right mixing chamber 42; taking the left chamber 3 as an example, after the hot fluid comes out of the left air chamber outlet 312, the hot fluid close to the left air inlet 311 has a higher temperature than the hot fluid close to the partition 2, so the hot fluid close to the partition 2 will flow to the partition 2 for mixing, thereby causing the temperature of the hot fluid close to the left air inlet 311 and the hot fluid close to the partition 2 to tend to be balanced during the mixing process.

[0055] Further, a left wavy guide plate 5 is provided on the left air cavity outlet 312, and the left wavy guide plate 5 is fixedly connected to the left air inlet cavity 31, and is spaced apart from the left wavy guide plate 5 and the inner wall of the housing 1; the left wavy guide plate 5 can be used to guide the wind flowing out of the left air cavity outlet 312 to the left inner wall of the housing 1 and the right inner wall of the housing 1;

[0056] A right wavy guide plate 6 is provided on the right air cavity outlet 412, and the right wavy guide plate 6 is fixedly connected to the right air inlet cavity 41 and is spaced apart from the inner wall of the outer shell 1; the right wavy guide plate 6 can be used to guide the wind flowing out of the right air cavity outlet 412 to the right inner wall of the outer shell 1 and the right inner wall of the outer shell 1.

[0057] The left wavy guide plate 5 and the right wavy guide plate 6 evenly distribute the hot fluid wind flowing out of the left air cavity outlet 312 and the right air cavity outlet 412 to each space of the left cavity 3 and the right cavity 4, reorganize the irregular fluid, improve the overall uniformity of the fluid in the air nozzle before entering the air outlet 11, and improve the uniformity of the air outlet temperature.

[0058] Specifically, the guide direction of the left wavy guide plate 5 is perpendicular to the air outlet direction of the left air cavity outlet 312;

[0059] The flow guiding direction of the right wavy guide plate 6 is perpendicular to the air outlet direction of the right air cavity outlet 412 .

[0060] Taking the left chamber 3 as an example, after the hot fluid flows out from the left air chamber outlet 312, it turns 90 degrees under the action of the left wavy guide plate 5 and flows out from the left wavy guide plate 5 to contact the inner wall of the shell 1, that is, the air outlet center of the left wavy guide plate 5 is perpendicular to the inner wall of the shell 1, so that the hot fluid is more easily and evenly distributed to all corners of the first left mixing chamber 32, which helps to ensure that the temperature or pressure distribution of the first left mixing chamber 32 is more uniform, avoiding local overheating or excessive pressure.

[0061] Furthermore, the partition plate 2 is arranged in the middle of the inner cavity of the shell 1, and the air nozzle in this embodiment is symmetrically arranged with the partition plate 2 as the center, so that the air outlet on both sides of the air nozzle is uniform.

[0062] Furthermore, the left air chamber outlet 312, the right air chamber outlet 412 and the air outlet 11 are strip-shaped and arranged along the length direction of the shell 1. Specifically, the air outlet 11 is a slender slit, and the air outlet at each point in the length direction of the air outlet 11 is continuous and the air outlet speed is uniform, thereby improving the drying quality.

[0063] Specifically, the air outlet 11 is provided in the middle of the housing 1;

[0064] The left air cavity air outlet 312 is located in the middle of the left cavity 3;

[0065] The right air cavity air outlet 412 is located in the middle of the right cavity 4 .

[0066] The air outlet 11, the left air cavity air outlet 312 and the right air cavity air outlet 412 are located on the same vertical plane, so that the hot fluids on both sides of the vertical plane are evenly mixed.

[0067] Furthermore, the housing 1 is also provided with a front deflector 7 and a rear deflector 8;

[0068] The front guide plate 7 is arranged at one end of the air outlet 11 facing the outside of the shell 1; the rear guide plate 8 is arranged at one end of the air outlet 11 facing the outside of the shell 1; the front guide plate 7 and the rear guide plate 8 are arranged parallel to each other to concentrate the wind force and direct the air outlet, so that the hot fluid can accurately act on the material to be dried, thereby improving the drying effect.

[0069] Since the air outlet 11 is narrow and the air outlet pressure is high, the front deflector 7 and the rear deflector 8 may shake and deform during the air outlet process; specifically, the front deflector 7 is provided with a front air nozzle reinforcement strip 81 arranged on the side facing away from the rear deflector 8; the rear deflector 8 is provided with a rear air nozzle reinforcement strip 82 arranged on the side facing away from the front deflector 7, which can strengthen the strength of the front deflector 7 and the rear deflector 8 to avoid bending and shaking of the front deflector 7 and the rear deflector 8, which affects the uniformity of the air outlet from the air nozzle.

[0070] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
