Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The utility model embodiment discloses a suction control device, as shown in the attached Figure 1As shown, the connecting box 1 and the driving member 4 are included. The connecting box 1 can be a cubic structure surrounded by six side panels, and has a closed connecting cavity 11 therein. However, the structure of the connecting box 1 is not limited thereto. The two ends of the connecting cavity 11 are respectively connected to the first gas path 2 and the second gas path 3 in a straight line. The first gas path 2 is used to connect the high-pressure blower, and the second gas path 3 is used to connect the table.

[0033] The movable end of the driving member 4 is fixedly provided with a windshield 5, and the windshield 5 is located in the connecting chamber 11. The driving member 4 is used to drive the windshield 5 to move along the cross-sectional direction of the connecting chamber 11, so that the connecting chamber 11 is connected to or disconnected from the first gas path 2 and the second gas path 3 accordingly. When the windshield 5 does not cut off the connecting chamber 11, the windshield 5 does not work, and the two ends of the connecting chamber 11 are respectively connected to the first gas path 2 and the second gas path 3 in a straight line, so that the high-pressure fan is connected to the table, and the high-pressure fan is in a suction state; when the windshield 5 cuts off the connecting chamber 11, the windshield 5 works, cuts off the first gas path 2 and the second gas path 3, and disconnects the high-pressure fan from the table, and the high-pressure fan is in a non-suction state.

[0034] In summary, the utility model optimizes the structure of the air suction control device, so that the driving member 4 drives the wind shield 5 provided at its fixed end to move along the cross-sectional direction of the connecting box 1, and changes the connection state of the connecting cavity 11 by changing the opening of the connecting cavity 11 on the cross-sectional direction. Under the premise of not affecting the high-pressure blower to achieve two working states, the connecting box 1 in the utility model can make the first gas path 2 and the second gas path 3 connected in a straight line, eliminate the bend design between the two gas paths, and effectively reduce gas path loss.

[0035] The driving member 4 is specifically a cylinder, the cylinder barrel of the cylinder is fixedly arranged, and the piston rod 41 of the cylinder includes at least two, and all the piston rods 41 are fixedly connected to the windshield 5. The side wall of the connecting box 1 is provided with at least two guide holes, and all the piston rods 41 can slide through all the guide holes one by one, so that each guide hole guides the piston rod 41 therein to slide smoothly, and the arrangement of multiple piston rods 41 can prevent the windshield 5 from getting stuck due to the tilt of the movable end of the piston rod 41, ensuring the smooth movement of the windshield 5. The driving member 4 is specifically fixed with two piston rods 41, and the two piston rods 41 are linearly distributed. Of course, the type of the driving member 4 is not limited to the cylinder, and it can also be replaced by a linear driving member 4 such as a linear motor, which does not affect the purpose of achieving the present utility model.

[0036] The movable end of the piston rod 41 is fixed with a fixed plate 42 in an integral manner, and the fixed plate 42 is fixed with a connecting plate 43 in parallel. The connecting plate 43 is vertically connected to the windshield 5, so that the fixed plate 42 drives the windshield 5 to move synchronously through the connecting plate 43. The windshield 5 can be slidably inserted into the connection box 1 to ensure that the windshield 5 has a large enough moving space and prevent the windshield 5 from being completely drilled into the connection box 1 and getting stuck. Flexible pads 44 are respectively fixed on both sides of the connection plate 43. The flexible pads 44 are used to seal the gap between the piston rod 41 and the connection box 1 when the windshield 5 cuts off the connection cavity 11, ensuring that the connection box 1 has good sealing performance. The flexible pads 44 are also used to achieve shock absorption when the windshield 5 collides with the connection box 1, avoiding excessive impact when the windshield 5 collides with the connection box 1. The flexible pad 44 can be a rubber pad, but is not limited thereto. The length of the flexible pad 44 is close to the length of the connection cavity 11, and the widths of the flexible pad 44 and the windshield 5 are equal to the width of the connection cavity 11.

[0037] A guide hole is provided on the side of the connection box 1 for the windshield plate 5 to slide through, and a seal is provided between the windshield plate 5 and the guide hole and between the piston rod 41 and the guide hole, so that the connection box 1 has good sealing performance and prevents air leakage during the movement of the windshield plate 5. The seal can be a rubber seal ring, but is not limited thereto.

[0038] The above-mentioned air suction control device also includes a detection member and a controller. The detection member is used to detect whether the connecting plate 43 abuts against the side wall of the connecting box 1. Specifically, it can be a pressure sensor, a contact sensor or a travel switch. The controller is connected to the detection member and the driving member 4 respectively. When the detection member detects that the connecting plate 43 abuts against the side wall of the connecting box 1, the detection member feeds back a signal to the controller. After receiving the signal, the controller controls the driving member 4 to stop the action to prevent the fixing plate 42 from excessively moving and colliding with the connecting box 1.

[0039] It should be noted that the controller should include a signal receiving part, a signal judging part and a signal sending part. The signal receiving part is used to receive the electrical signal sent by the detection part. The signal judging part and the signal receiving part are electrically connected so that the signal judging part is used to judge whether the signal received by the signal receiving part is a trigger signal. The signal sending part and the signal judging part are electrically connected so that the signal sending part sends the judgment signal generated by the signal judging part to the driving part 4. The specific setting methods of the signal receiving part, the signal judging part and the signal sending part can refer to the prior art; in the present utility model, only the application scenarios of the above three are changed, and no substantial improvement is made thereto. Obviously, the controller with this structure is widely used in existing automatic control equipment, such as MCU, DSP or single-chip microcomputer. The key point of the present utility model is that the controller combines the detection part and the controller.

[0040] The first connection hole and the second connection hole are respectively provided on two opposite sides of the connection box 1. The first connection hole and the second connection hole are coaxially arranged to ensure that the first gas path 2 and the second gas path 3 are linearly connected through the connection cavity 11 to avoid excessive gas path loss. The first connection hole is sealed and connected to the first gas path 2, and the second connection hole is sealed and connected to the second gas path 3 to prevent air leakage. Specifically, a sealing ring or a sealant can be added between the first connection hole and the first gas path 2 and between the second connection hole and the second gas path 3.

[0041] A stop block is fixedly provided at one end of the windshield plate 5 , and the stop block is located outside the connection box 1 . The stop block is used to prevent the windshield plate 5 from completely drilling into the connection cavity 11 , so as to prevent the windshield plate 5 from getting stuck in the connection box 1 .

[0042] As attached Figure 2 and 3 As shown, the side wall of the connection box 1 is provided with an air suction port 12, and the air suction port 12 is connected to the connection chamber 11. The air suction port 12 is movably provided with an air volume adjustment plate 13, and the air volume adjustment plate 13 is used to adjust the opening of the air suction port 12, thereby adjusting the suction force of the connection box 1. When the air volume adjustment plate 13 moves to the left to the extreme position, the air suction port 12 is closed, and the suction force of the air suction port 12 reaches the maximum. When the air volume adjustment plate 13 moves to the right to the extreme position, the air suction port 12 is opened to the maximum, and the suction force of the air suction port 12 reaches the minimum.

[0043] The air volume adjustment plate 13 is provided with a waist-shaped hole 131, and the waist-shaped hole 131 is installed with an adjusting screw 14. When the air suction port 12 reaches the ideal opening, tighten the adjusting screw 14 to fix the air volume adjustment plate 13 on the side wall of the connection box 1. When the opening of the air suction port 12 needs to be adjusted, it is only necessary to loosen the adjusting screw 14. Specifically, a rectangular hole is provided in the center of the air volume adjustment plate 13, and the rectangular hole is the air suction port 12. The air volume adjustment plate 13 is rectangular, and each of its four corners is provided with a waist-shaped hole 131, and each waist-shaped hole 131 is equipped with an adjusting screw 14. The air volume adjustment plate 13 is integrally provided with a limit block for limiting the position of the air volume adjustment plate 13 to prevent the air volume adjustment plate 13 from excessive movement. Of course, the structure and fixing method of the air volume adjustment plate 13 are not limited to this.
