The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example 1
Referring to fig. 1 to 5, the invention provides an air volume adjusting device, which comprises an air duct cover plate 1, a baffle plate 2, a connecting plate 3, a first slider 4 and a second slider 5, wherein a chute 1-1 and an air outlet 1-2 are respectively arranged on two sides of the air duct cover plate 1, a first end 2-1 of the baffle plate 2 is rotatably connected with the air duct cover plate 1, an arc-shaped groove 2-3 is arranged in the middle of the baffle plate 2, the first slider 4 and the second slider 5 are respectively slidably embedded in the chute 1-1 and the arc-shaped groove 2-3, the first slider 4 is connected with the second slider 5 through the connecting plate 3, and the length of the baffle plate 2 is such that the second end 2-2 of the baffle plate 2 can shield the air outlet 1-2 when the first slider 4 moves a specified distance in the chute 1-1.
When the air volume needs to be increased, a user can directly push the first slider 4 rightwards, namely towards the direction of the air outlet 1-2, and the first slider 4 is connected with the second slider 5 through the connecting plate 4, so that the pushing force can drive the second slider 5 to horizontally move rightwards for the same distance after being transmitted through the first slider 4 and the connecting plate 3, meanwhile, the second slider 5 is embedded in the arc-shaped groove 2-3, the linear motion of the second slider 5 can drive the baffle 2 to rotate downwards under the action of the arc-shaped groove 2-3, namely, the second end 2-2 of the baffle 2 performs circular motion by taking the first end 2-1 as a circle center to gradually keep away from the air outlet 1-2, and then the air outlet 1-2 can be gradually opened along with the continuous downward rotation of the second end 2-2 of the baffle 2.
When the air volume needs to be reduced, a user can directly push the first slider 4 leftwards, namely, the first slider 4 is pushed in the direction away from the air outlet 1-2, and the first slider 4 is connected with the second slider 5 through the connecting plate 4, so that the pushing force can drive the second slider 5 to horizontally move leftwards for the same distance after being transmitted through the first slider 4 and the connecting plate 3, meanwhile, the second slider 5 is embedded in the arc-shaped groove 2-3, the linear motion of the second slider 5 can drive the baffle 2 to start to rotate upwards under the action of the arc-shaped groove 2-3, namely, the second end 2-2 of the baffle 2 performs circular motion by taking the first end 2-1 as the circle center to gradually approach the air outlet 1-2, and then the air outlet 1-2 can be gradually shielded by the baffle 2 along with the continuous upward rotation of the second end 2-2 of the baffle 2.
Therefore, the connecting plate 3, the first slider 4 and the second slider 5 move synchronously, the first slider 4 is pushed manually to indirectly drive the second slider 5 to drive the baffle 2 to rotate, so that the linear motion of the first slider 4 can be converted into the rotation of the baffle 2, and the horizontal movement distance of the first slider 4 is in direct proportion to the rotation angle of the baffle 2, so that the stepless regulation of the air volume can be realized by regulating the horizontal movement distance of the first slider 4, namely, the continuous regulation of the air volume can be realized according to the area of the baffle 2 for shielding the air outlets 1-2. In addition, the actual experience of the user can be obviously improved through man-machine interaction, so that the selling point is displayed.
Preferably, the first slider 4 and/or the second slider 5 are integrally formed with the connecting plate 3. For example, the first slider 4 and/or the second slider 5 are protrusions punched on the connecting plate 3.
Preferably, the width of the baffle 2 is adapted to the height of the air outlet 1-2, that is, the width of the baffle 2 is equal to or slightly greater than the height of the air outlet 1-2, so that the material can be saved, the horizontal movement distance of the first sliding block 4 can be ensured to be in one-to-one correspondence with the opening degree of the air outlet 1-2, and the adjusting efficiency is improved.
