DETAILED DESCRIPTION

[0019] like Figures 1-4 As shown, the utility model provides a technical solution: a simulated airflow control device that is convenient for air intake, including a device body 1, a base 2 is fixedly installed at the bottom of the device body 1, an air inlet 3 is fixedly installed on the outer wall of the device body 1, a cover plate 4 is hinged on the outer wall of the device body 1, an observation window 5 is arranged on the outer wall of the device body 1, an air outlet 6 is opened on the side wall of the device body 1, an adjustment mechanism 7 is arranged on the inner wall of the device body 1, and an auxiliary mechanism 8 is arranged on the inner wall of the device body 1.

[0020] The above-mentioned adjustment mechanism 7 includes: a hexagonal groove 701, a slider 702, a triangular sealing plate 703, a hollow disc 704, a through groove 705, a resistance rod 706, and a groove rod 707. The hexagonal groove 701 is provided on the inner wall of the device body 1, and the slider 702 is slidably installed on the inner wall of the hexagonal groove 701. The outer wall of the slider 702 is fixedly installed with a triangular sealing plate 703. The slider 702 is provided with six groups, which are arranged in a circular array on the inner wall of the hexagonal groove 701, and the outer walls of the six groups of sliders 702 are all fixedly installed with triangular sealing plates 703. The inner wall of the device body 1 is rotatably installed with a hollow disc 704, and the inner wall of the hollow disc 704 is provided with a through groove 705. The outer wall of the triangular sealing plate 703 A resistance rod 706 is fixedly installed, one end of the resistance rod 706 is fixedly installed on the outer wall of the triangular sealing plate 703, and the outer wall of the other end of the resistance rod 706 is fitted with the inner wall of the through groove 705. A groove rod 707 is fixedly installed on the outer wall of the hollow disc 704. When the device body 1 needs to be used, the cover plate 4 is opened and the groove rod 707 is bent to make the groove rod 707 drive the hollow disc 704 to rotate. While the hollow disc 704 rotates, the through groove 705 will squeeze the resistance rod 706 to make the resistance rod 706 drive the triangular sealing plate 703 to open. The air intake of the air inlet 3 is controlled by controlling the size of the opening of the triangular sealing plate 703. When it is adjusted to a suitable size, the bending of the groove rod 707 is stopped.

[0021] The auxiliary mechanism 8 comprises: a baffle 801, a streamline groove 802, and a round rod 803. The baffle 801 is slidably mounted on the inner wall of the device body 1. The baffle 801 is made of transparent acrylic material. The inner wall of the baffle 801 is provided with a streamline groove 802. The outer wall of the baffle 801 is fixedly mounted with a round rod 803. The baffle 801 is provided with two groups, which are mirror-set with the center line of the device body 1 in the vertical direction as the axis of symmetry. The outer walls of the two groups of baffles 801 are fixedly mounted with round rods 803. One end of the round rod 803 is fixedly mounted on the outer wall of the baffle 801, and the other end of the round rod 803 is fixedly mounted on the outer wall of the baffle 801. The outer wall is in contact with the inner wall of the groove rod 707. When the groove rod 707 is bent, the groove rod 707 will squeeze the round rod 803 to make the two groups of baffles 801 move away from each other. The distance that the baffles 801 move away from each other is related to the size of the opening of the triangular sealing plate 703. The larger the air inlet 3 leaking out through the triangular sealing plate 703 is, the farther the baffles 801 move away from each other. If the air inlet 3 leaking out through the triangular sealing plate 703 is smaller, the distance that the baffles 801 move away from each other is smaller. The flow speed of the airflow on the streamline groove 802 can be observed through the observation window 5.

[0022] Working principle: when the device body 1 needs to be used, the cover plate 4 is opened and the slot rod 707 is moved to make the slot rod 707 drive the hollow disc 704 to rotate. While the hollow disc 704 rotates, the through slot 705 will squeeze the resistance rod 706 to make the resistance rod 706 drive the triangular sealing plate 703 to open. The air intake of the air inlet 3 is controlled by controlling the opening size of the triangular sealing plate 703. When the opening size is adjusted to a suitable size, the slot rod 707 is stopped from being moved. While the slot rod 707 is being moved, the slot rod 707 will squeeze the round rod 803 to make the two sets of baffles 801 move away from each other. The distance that the baffles 801 move away from each other is related to the opening size of the triangular sealing plate 703. The larger the air inlet 3 is opened through the triangular sealing plate 703, the more air is leaked out. , the farther the baffles 801 are from each other, if the triangular sealing plate 703 is opened and the leaking air inlet 3 is smaller, the smaller the baffles 801 are from each other, at this time, close the cover plate 4, and send air to the inner wall of the device body 1 through the air inlet 3. At this time, observe the flow speed of the airflow on the streamline groove 802 through the observation window 5. After the simulation experiment, open the cover plate 4, bend the groove rod 707 to reverse the hollow disc 704. At this time, the through groove 705 will squeeze the resistance rod 706 so that the resistance rod 706 drives the triangular sealing plate 703 to reverse and reset and close the air inlet 3. While bending the groove rod 707, the groove rod 707 will squeeze the round rod 803 to make the two groups of baffles 801 close to each other and reset.

[0023] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and concept of the present utility model are all within the protection scope of the present utility model.
