Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the utility model provides an air volume converter, as shown in fig. 1-4, including box 1, switching mechanism 2, one side of box 1 sets up air outlet 11, and the opposite side sets up two air intakes 12 and two air intakes 12 are the angle setting, switching mechanism 2 sets up and is used for opening an air intake 12 and closing an air intake 12 along with the control of opening mode between two air intakes 12, and like this, when opening the fan that one of them air intake 12 corresponds, switching mechanism 2 swings to opposite side air intake 12 under the wind-force effect, just opens the air intake 12 of opening, and another air intake 12 closes.
The switching mechanism 2 comprises a base 21, a rotating shaft 22 and a baffle 23, wherein the base 21 is located at the center of the two air inlets 12, and one end of the baffle 23 is rotatably arranged in the base 21 through the rotating shaft 22.
One end of the rotating shaft 22 extends to the outside of the cabinet 1 and is connected with a pointer 24 for visually determining to which side of the intake vent 12 the flap 23 is currently swung.
The cross section of the base 21 is convex, two sides of the base are fixed in the box body 1 through bolts, and a through hole in the middle of the base is connected with the rotating shaft 22 in a matching mode.
Arc-shaped slide ways 13 matched with the swing motion tracks of the baffle plates 23 are arranged on two side faces of the box body 1, and slide blocks matched with the arc-shaped slide ways 13 are arranged on two sides of each baffle plate 23, so that the stability of the baffle plates 23 in a swing mode is ensured.
Each two sides of the air inlet 12 are provided with an L-shaped sealing frame 121, a non-metal sealing strip 122 is arranged in the L-shaped sealing frame 121, and the non-metal sealing strip 122 is higher than the end surface of the air inlet 12, and is used for playing a role in buffering when the baffle 23 swings to the air inlet 12, and playing a role in sealing when the baffle 23 covers and presses the air inlet 12.
The back of the box body 1 is provided with a detection window 14 for maintaining and overhauling the switching mechanism 2.
The two air inlets 12 are arranged at 90 degrees.
The utility model discloses a work engineering:
the utility model discloses use in spouting the ammonia system, the ammonia dilution fan sets up two sets of fans, two air intakes 12 one are in the open mode, and another is in the closed mode, and two outlet air 12 need switch according to the operational aspect, baffle 23 lid is pressed on the air intake 12 of closing one side, and another air intake 12 is opened and normally works, because baffle 23 lid is pressed on the air intake 12 of closing one side, this side can not produce the negative pressure, and normal air current can not flow back to in the air intake 12; when the two air inlets 12 need to be switched, the air inlet 12 which is closed before generates wind power due to the action of the fan, and the baffle 23 swings to the air inlet 12 on the other side to cover and press the air inlet 12 under the pushing of the wind power, so that the switching of the two air inlets 12 is realized, and the air volume conversion is carried out.
