[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0025] See also Figure 1-4The utility model discloses a nozzle, including a nozzle body 1, wherein the nozzle body 1 is provided with an air inlet surface and an air spray surface 12, the air inlet surface is provided with an air inlet 11, the air spray surface 12 is provided with a spray hole 121, a spray cavity 13 is provided in the nozzle body 1, and the air inlet 11 is connected with the spray hole 121 through the spray cavity 13.

[0026] The spray hole 121 is provided with an air guide ring 122 . The air guide ring 122 is formed by extending from the edge of the spray hole 121 into the spray cavity 13 , and the air guide ring 122 is protruding into the spray hole 121 .

[0027] The nozzle of the utility model is provided with an air guide ring on the spray hole. The air guide ring can guide the wind on one hand, and on the other hand, the hot wind is sprayed out of the spray hole along the convex surface of the air guide ring, which has small wind resistance and small wind pressure loss, so that the hot wind can be blown to the cloth at a large flow rate, and the heat loss is also reduced, thereby effectively improving the drying speed of the cloth. Secondly, there are no protruding objects on the spray surface, which will not interfere with the cloth, thereby effectively protecting the cloth during the drying process. Moreover, the structure is simple, reliable and low in cost.

[0028] Specifically, the cross-section of the air guide ring 122 is arc-shaped. The arc-shaped surface guides the hot air and reduces the wind resistance of the hot air, so that the hot air can flow out of the spray hole quickly with a high wind speed, and also reduces the heat loss.

[0029] Preferably, the air-spraying surface 12 and the air-guiding ring 122 are integrally formed, which has a simple and reliable structure and low manufacturing cost.

[0030] Preferably, if Figure 2 As shown, the longitudinal cross-section of the nozzle body 1 is a right triangle. The air inlet surface and the air ejection surface 12 are vertically connected to each other. The nozzle body 1 is also provided with an air guide surface 14, which is respectively connected to the air inlet surface and the air ejection surface 12, and the angle α between the air guide surface 14 and the air ejection surface 12 is 5°-30°. More preferably, the angle α between the air guide surface 14 and the air ejection surface 12 is 10°-20°.

[0031] Hot air flows into the spray chamber from the air inlet at a relatively high speed, and is ejected from the nozzle outside the nozzle along the air guide ring and the arc surface of its inner wall, thereby blowing toward the surface of the fabric. The setting of the air guide surface can gradually reduce the volume of the spray chamber, so that the wind speed flowing into the spray chamber gradually increases from the air inlet to the part away from the air inlet, thereby avoiding uneven wind speed flowing into the spray chamber, which causes different wind speeds at different positions on the nozzle, affecting the drying effect. Specifically, the cross-sectional area of ​​the spray chamber gradually decreases from the air inlet to the opposite side of the air inlet surface.

[0032] Furthermore, the number of the nozzle bodies 1 is at least two and they are arranged side by side. The arrangement of multiple nozzle bodies can increase the hot air volume and speed up the drying speed.

[0033] Preferably, the nozzle bodies 1 are arranged at intervals to reduce wind resistance and prevent wind from rebounding back to the nozzle and exerting a huge wind pressure on the nozzle, which affects the normal air output of the nozzle and also causes a lot of noise.

[0034] Furthermore, the utility model also includes a connection assembly, which includes at least two connection frames 2, and the two ends of the nozzle body 1 are respectively fixedly connected to the connection frames 2. The two ends of multiple nozzle bodies are fixed by the connection frames to form a whole, which is convenient for subsequent installation.

[0035] Accordingly, see Figure 5 The utility model also discloses a drying device, which is provided with the above-mentioned nozzle. The specific structure of the nozzle is as described above, and will not be repeated here.

[0036] like Figure 5 As shown, the two nozzle bodies 1 are axially symmetrical and spaced apart, wherein the air jet surfaces 12 are arranged opposite to each other, and a cloth passing channel 3 is formed between the two air jet surfaces 12. The cloth moves in the cloth passing channel, and the nozzles spray hot air toward the cloth to dry the cloth.

[0037] In summary, the utility model provides a nozzle and a drying device equipped with the nozzle, which effectively protects fabrics while having high wind speed and low heat loss.

[0038] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
