According to an embodiment of the present invention, as shown in fig. 1 and 2, it can be seen that the nozzle device includes:
a nozzle front case 110 having a middle portion in a ring shape and a height greater than a width;
a nozzle rear case 120 symmetrically distributed in a radial direction with the nozzle front case 110; and
at least one liner plate 30 disposed within the nozzle front shell 110;
the front nozzle shell 110 and the rear nozzle shell 120 are closely attached to form an airflow channel 121, so that the airflow entering the airflow channel is not leaked, and the strength of the discharged airflow is ensured.
The nozzle front shell 110 is provided with air outlet frames 111 at intervals;
the air outlet frames 111 are symmetrically distributed on the front nozzle shell 110.
The nozzle front case 110 and the nozzle rear case 120 each include two vertical sections 113 and one curved section 114;
the curved section 114 connects the upper ends of the two vertical sections 113, and the lower ends of every two vertical sections 113 extend downward and inward to form a hollow protrusion, so as to form a receiving space in a wrapping manner, where the receiving space is used for storing the splitter 20 of the bladeless fan, so as to save a structural space, and also enable the splitter 20 to be tightly attached to the nozzle device 10, thereby ensuring that an air flow smoothly enters the nozzle device 10.
The connection part of the curved section 114 and the vertical section 113 is provided with a blocking baffle 112, the curved section 114 and the vertical section 113 are integrally formed, the blocking baffle 112 can effectively prevent the airflow from being transmitted upwards to the top end of the spray head, and the problem that the airflow is in a ring shape in the curved section 140 to cause airflow collision, so that the airflow is not uniformly distributed in the channel, and the uniformity of airflow injection is further influenced is solved.
Referring to fig. 3, 4 and 5, it can be seen that a concave-convex structure 130 is disposed between the front nozzle shell 110 and the rear nozzle shell 120, a protrusion 131 is disposed on a surface of the front nozzle shell 110 facing the rear nozzle shell 120, a groove 132 is disposed on a surface of the rear nozzle shell 120 facing the front nozzle shell 110, wherein the groove 132 is matched with the protrusion 131, and the concave-convex structure 130 is assembled with the convex structure 130 by using glue, so as to enhance the sealing property between the front nozzle shell 110 and the rear nozzle shell 120.
In a specific embodiment, the positions of the protrusions 131 and the grooves 132 may be interchanged or crossed.
As shown in fig. 1, the liner plate 30 is in the formed airflow channel 121, and the liner plate 30 is in a v shape as a whole;
the angle formed by the liner plate 30 is smaller than the angle formed by the nozzle front shell 110, and at least partially overlaps with the nozzle front shell 110.
Referring now to fig. 6 and 7, the liner plate 30 is formed by joining one end of a wide plate 310 and one end of a narrow plate 320.
the number, shape and position of the air outlet 350 are consistent with those of the air outlet frame 111.
In a specific embodiment, when an external air flow enters the interior of the bladeless fan through the lower filtering device 20 of the bladeless fan, the driving device inside the bladeless fan drives the air flow to flow upwards into the air flow channel 121 formed by the front nozzle shell 110 and the rear nozzle shell 120, when the air flow flows into the spray head device 10 from the flow divider 20, the air flow is rushed towards the curved section 114 due to the large wind force of the air flow, the blocking baffle 112 blocks the air flow and returns downwards into the vertical section 113, so that the energy loss of the air flow is reduced, the air flow collides in the vertical section 113, and the air flow is ejected from the air outlet frame 111 due to the fact that only the front nozzle shell 110 of the spray head device 10 is provided with the air outlet frame 111; only preceding shell 110 of nozzle is provided with it has guaranteed to go out wind frame 111, the air current is discharging the power of wind-force during the bladeless fan, it is just for the rectangle to go out wind frame 111 sets up with interval on two vertical sections 113, make the air current is discharging during the bladeless fan, it is more smooth and easy, and its simple structure, the installation of being convenient for has reduced the wearing and tearing in dismantlement or installation, has improved its life.
Since the lining plate 30 is disposed in the vertical section 114 of the nozzle front housing 110 and has a V-shape, the air flow enters from a large opening of the V-shape and is discharged from a small opening, and the lining plate 30 is disposed to prevent the problem of noise caused by the unsmooth air flow due to the roughness and noise of the nozzle front housing 110.
Since the angle of the lining plate 30 is smaller than that of the nozzle front case 110, the inner space of the airflow channel 121 is reduced, and when the airflow enters the airflow channel 121 from the lower filter device 20 of the bladeless fan at a very high speed, a pressure difference is generated, so that the airflow discharged from the bladeless fan is strong in rheology, and the discharge of the airflow is accelerated.
