[0011] The following is a clear and detailed description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0012] Below, embodiments of the present invention will be described in detail. However, the present invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments illustrated herein. Rather, these exemplary embodiments are provided to provide a thorough and detailed understanding of the present invention to those skilled in the art.

[0013] Please refer to Figures 1 to 4 The present invention provides a nozzle 100, which is suitable for an external device 200 such as a fog machine, and is used to change the spray shape of the gas sprayed by the external device 200. In this embodiment, the gas may also include mist sprayed by the fog machine, which is not limited here.

[0014] The nozzle 100 of the present invention sequentially defines an air inlet 10, a gas passage 20, and an exhaust port 30. The air inlet 10 and the exhaust port 30 have different shapes. By configuring the air inlet 10 and the exhaust port 30 differently, the gas ejected from the external device 200 can be ejected in a predetermined shape, such as a fan, a line, or an arc. In this embodiment, the nozzle 100 is positioned within the external device 200, so that the gas ejected from the external device 200 is ejected in a line-like shape.

[0015] Furthermore, the nozzle 100 includes an air inlet portion 40 , a flow guide portion 50 and an air exhaust portion 60 , which are sequentially arranged.

[0016] Specifically, the air intake portion 40 is fixedly connected to the external device 200, and an air inlet 10 is provided at one end of the air intake portion 40 away from the exhaust portion 60. The air inlet 10 is connected to the air outlet (not shown) of the external device 200, so that the gas ejected from the external device 200 can sequentially enter the air inlet 10 and the gas channel 20, and finally be discharged through the exhaust port 30.

[0017] In this embodiment, the air inlet 10 is circular in shape. Of course, in other embodiments, the air inlet 10 may also be in other approximately circular shapes, such as an elliptical shape, which is not limited here.

[0018] In this embodiment, a first gas channel 41 is provided inside the air inlet portion 40, one end of the first gas channel 41 (i.e., the air inlet 10) is connected to the air outlet of the external device 200, and the other end is connected to multiple branch channels of the guide portion 50 described later. The first gas channel 41 is part of the gas channel 20.

[0019] In this embodiment, the cross-section of the first gas channel 41 along the width of the nozzle 100 is rectangular, and the width of the first gas channel 41 along the thickness of the nozzle 100 decreases as it approaches the flow guide 50. It will be appreciated that the width of the first gas channel 41 decreases as it approaches the flow guide 50, thereby matching the width of the second gas channel 61 of the exhaust portion 60 described later.

[0020] From the cross section along the width direction of the nozzle 100 , the air inlet portion 40 includes two first side walls 43 opposite to each other. The two first side walls 43 are arranged in parallel, and the first gas channel 41 is formed between the two first side walls 43 .

[0021] Furthermore, the air inlet portion 40 is provided with a connecting portion 44 , which is used to connect with the external device 200 , so that the nozzle 100 is detachably fixed to the external device 200 .

[0022] One end of the guide portion 50 is connected to the air intake portion 40, and the other end is connected to the exhaust portion 60, that is, the guide portion 50 is arranged between the air intake portion 40 and the exhaust portion 60, and a guide structure 51 is arranged in the guide portion 50, which is used to guide the gas entering from the air intake portion 40 to the exhaust portion 60.

[0023] It can be understood that in this embodiment, the width of the first gas channel 41 in the air intake section 40 is much smaller than the width of the second gas channel 61 in the exhaust section 60. By providing the guide structure 51, the gas in the air intake section 40 can be effectively and evenly guided to the entire width of the second gas channel 61, so that the gas is discharged in a linear and uniform manner.

[0024] Specifically, the flow guide structure 51 includes a first flow guide member 511 and a second flow guide member 512. The first flow guide member 511 is disposed approximately in the center of the flow guide portion 50, thereby forming at least two branch channels 53 within the flow guide portion 50. The two ends of each branch channel 53 are respectively connected to the first gas channel 41 of the air inlet portion 40 and the second gas channel 61 of the exhaust portion 60, which will be described later. It will be understood that the first gas channel 41 of the air inlet portion 40, the at least two branch channels 53 within the flow guide portion 50, and the second gas channel 61 of the exhaust portion 60 collectively form the gas channel 20 within the nozzle 100.

[0025] In this embodiment, the at least two branch channels 53 include a first branch channel 531 and a second branch channel 532 . The first branch channel 531 and the second branch channel 532 are arranged on both sides of the first flow guide 511 and are symmetrically arranged relative to the center line L of the nozzle 100 .

[0026] Furthermore, the extension direction of at least a portion of each branch channel is inclined relative to the extension direction of the first gas channel 41 of the air inlet 40 , and the distance between each branch channel and the center line L of the nozzle 100 increases as the distance from the air inlet 40 increases.

[0027] The guide portion 50 includes two first guide walls 54 formed on the outside and two second guide walls 55 formed on both sides of the first guide member 511. A first branch channel 531 is formed between one first guide wall 54 and the corresponding second guide wall 55, and a second branch channel 532 is formed between the other first guide wall 54 and the other second guide wall 55. The distance between the first branch channel 531 and the second branch channel 532 increases as they move away from the air intake portion 40. In this way, the gas flowing in from the air intake portion 40 can be guided to both sides of the exhaust portion 60. It can be understood that the first branch channel 531 and the second branch channel 532 are formed by the first guide member 511 dividing the first gas channel 41.

[0028] In this embodiment, the first guide wall 54 is arranged at an angle relative to the first side wall 43 of the air inlet portion 40. The second guide wall 55 includes, from top to bottom, a first wall 551, a second wall 552, and a third wall 553. The first wall 551 is arranged parallel to the first side wall 43, and the second wall 552 is arranged parallel to the first guide wall 54. In this way, the first branch channel 531 is arranged at an angle relative to the first gas channel 41. The third wall 553 is arranged on the side of the second wall 552 close to the exhaust portion 60 and is arranged flush with the first side wall 43.

[0029] It should be noted that by providing the first wall 551 and the second wall 552, the gas in the first gas channel 41 can be effectively guided to the first branch channel 531, and the gas can flow along the first branch channel 531 between the second wall 552 and the first guide wall 54 to one side of the second gas channel 61 of the exhaust portion 60. Furthermore, at least a portion of the first guide member 511 protrudes from the first gas channel 41, which facilitates the flow of gas from the first gas channel 41 into the first branch channel 531 and the second branch channel 532.

[0030] Although two branch channels 53 are shown in the present embodiment, three, four or more branch channels 53 may be formed in other embodiments, and the present invention is not limited thereto. In the present embodiment, the first flow guide 511 is funnel-shaped.

[0031] The second air guide 512 is a protrusion formed between the first air guide wall 54 of the air guide portion 50 and the second side wall 62 of the exhaust portion 60 for guiding airflow.

[0032] Furthermore, the second air guide 512 is located closer to the exhaust portion 60 than the first air guide 511 .

[0033] The exhaust portion 60 is disposed on a side of the nozzle 100 away from the air inlet 40. An exhaust port 30 is provided in the exhaust portion 60 for discharging mist. In this embodiment, the exhaust port 30 is slit-shaped so that the gas ejected from the exhaust port 30 is linear, thereby achieving a uniform discharge effect in the form of linear sheets.

[0034] Of course, in other embodiments, the exhaust port 30 may also be in other shapes, such as a fan shape, an arc shape, etc., which is not limited here.

[0035] Furthermore, the exhaust portion 60 is provided with a second gas channel 61 for discharging the gas flowing into the guide portion 50. In this embodiment, the cross section of the second gas channel 61 along the width direction of the nozzle 100 is funnel-shaped.

[0036] In this embodiment, the width of the second gas channel 61 is greater than the width of the first gas channel 41. By setting the guide structure 51, the first guide member 511 can guide the gas in the first gas channel 41 to the side of the second gas channel 61, and the second guide member 512 can guide the gas in each branch channel to the center of the second gas channel 61, so that the gas can be discharged in a linear and uniform manner.

[0037] Furthermore, in the cross section along the thickness direction of the nozzle 100 , the width of the second gas channel 61 at one end close to the exhaust port 30 is greater than the width of the second gas channel 61 at one end close to the guide portion 50 , so as to facilitate demolding during the molding process and facilitate manufacturing.

[0038] In this embodiment, the exhaust portion 60 includes two second side walls 62 on both sides. The two side walls are arc-shaped, and the distance between the two side walls increases as the distance from the guide portion 50 increases, thereby making the second gas channel 61 fan-shaped.

[0039] In this embodiment, the second guide member 512 is a protrusion formed by the end of the second side wall 62 of the exhaust portion 60 close to the guide portion 50 protruding toward the center line L of the nozzle 100 compared to the end of the first guide wall 54 of the guide portion 50.

[0040] Furthermore, the exhaust portion 60 further includes third side walls 63 located on both sides. The two third side walls 61 are arranged in parallel, and the exhaust port 30 is formed between the two third side walls 63 .

[0041] In this embodiment, the nozzle 100 is an integrally formed component. It is understood that the nozzle 100 can be formed by a one-step injection molding method, which has a simple structure and a simple manufacturing method, which is conducive to reducing the number of process steps and thus reducing costs.

[0042] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
