[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the tabletop air duct switching device and the piano-style ironing table of the present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] The utility model provides a table air duct switching device, combined with Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, it includes table air duct 1, arm ironing air duct 2, and negative pressure channel 3. Figure 5 、 Figure 6As shown, the negative pressure channel 3 is connected to a negative pressure device 8, which can be an exhaust fan, to create a negative pressure in the negative pressure channel 3. The negative pressure channel 3 acts as a relay and is connected to the table air duct 1 and the arm ironing air duct 2, respectively. Air can flow between the negative pressure channel 3 and the table air duct 1, and between the negative pressure channel 3 and the arm ironing air duct 2.

[0034] A rotating baffle 4 is provided at the connection between the countertop air duct 1 and the negative pressure channel 3 to control air flow. The baffle 4 is rotatable, allowing the connection and disconnection between the countertop air duct 1 and the negative pressure channel 3. When the countertop air duct 1 and the negative pressure channel 3 are connected, negative pressure can exist within the countertop air duct 1; when they are disconnected, negative pressure disappears. An arm ironing baffle 5 is provided at the connection between the arm ironing duct 2 and the negative pressure channel 3 to control air flow. The baffle 5 is rotatable, allowing the connection and disconnection between the arm ironing duct 2 and the negative pressure channel 3. When the arm ironing duct 2 and the negative pressure channel 3 are connected, negative pressure can exist within the arm ironing duct 2; when they are disconnected, negative pressure disappears. The countertop air duct 1 is connected to the ironing surface and, when negative pressure is present, negative pressure can be applied to clothing placed thereon. The arm ironing duct 2 is connected to the ironing surface and, when negative pressure is present, negative pressure can be applied to clothing placed thereon. Both the ironing table and the ironing arm table can be used for ironing. The ironing table has a larger area and is suitable for ironing large areas of fabrics, while the ironing arm table has a smaller area and is suitable for ironing smaller areas such as sleeves.

[0035] The table baffle 4 and the ironing arm baffle 5 each have a rotating shaft that opens or closes their respective air ducts by rotating. The rotating shaft of the table baffle 4 and the rotating shaft of the ironing arm baffle 5 are parallel. A switching link 6 is hinged at one end to the table baffle 4 and at the other end to the ironing arm baffle 5, acting as an intermediate transmission. The rotating shaft of the table baffle 4 itself and the connecting axis between the table baffle 4 and the switching link 6 do not coincide. Similarly, the rotating shaft of the ironing arm baffle 5 and the connecting axis between the ironing arm baffle 5 and the switching link 6 do not coincide.

[0036] When either the table baffle 4 or the ironing arm baffle 5 rotates, the other is driven to rotate via the switching link 6. In other words, one of the table baffle 4 and the ironing arm baffle 5 rotates actively, while the other rotates passively via the switching link 6. When the table baffle 4 rotates actively, the ironing arm baffle 5 is driven to rotate passively by the switching link 6. When the ironing arm baffle 5 rotates actively, the table baffle 4 is driven to rotate passively by the switching link 6.

[0037] The arm ironing baffle 5 and the table baffle 4 rotate synchronously via the switching connecting rod 6. When the table air duct 1 forms a negative pressure, the arm ironing air duct 2 is automatically cut off. When the arm ironing air duct 2 forms a negative pressure, the table air duct 1 is automatically cut off. Only one of the table air duct 1 and the arm ironing air duct 2 forms a negative pressure by suction, cutting off the negative pressure of the unused table, ensuring that more sufficient suction is formed when the table or the arm ironing air duct is used alone.

[0038] On the basis of the above scheme, combined with Figure 2 As shown, the table baffle 4 and the arm baffle 5 are perpendicular to each other and are respectively mounted on two perpendicular side walls. The rotating axis of the table baffle 4 is parallel to the surface of the table baffle 4, while the rotating axis of the arm baffle 5 is perpendicular to the surface of the arm baffle 5. The bottom edge of the table baffle 4 is fixed parallel to its rotating axis, while the lower portion of the arm baffle 5 is perpendicular to the rotating axis. Of course, the present invention does not exclude the possibility of the table baffle 4 and arm baffle 5 being arranged parallel to each other; the effect of opening one channel while closing the other can still be achieved.

[0039] The rotating shafts of the table baffle 4 and the ironing arm baffle 5 are both arranged horizontally. Figure 1 、 Figure 3 As shown, the rotation axis of the table baffle 4 is arranged along the Y-axis, and the ironing arm baffle 5 is arranged along the Y-axis. The table baffle 4 is parallel to the YZ plane, and the ironing arm baffle 5 is parallel to the XZ plane. If the air duct structure is different, the rotation axes of the table baffle 4 and the ironing arm baffle 5 can also be arranged vertically.

[0040] Combine Figure 2 、 Figure 3 As shown, a switching handle 7 is provided at the rotating shaft of the table baffle 4, and the switching handle 7 is used to drive the table baffle 4 to swing.

[0041] Specifically, the switching handle 7 is configured as a handle for hand manipulation, and the table baffle 4 can be actively rotated by hand manipulation.

[0042] The switch handle 7 can also be provided with a driving link mechanism for foot-driven operation, thereby achieving foot-operated switching.

[0043] In a specific embodiment, a drive assembly is provided at the rotating shaft of the table baffle 4 or the rotating shaft of the ironing arm baffle 5; the drive assembly is a motor or a drive connecting rod. When the drive assembly is a motor, the motor outputs torque to drive the table baffle 4 to rotate. When the drive assembly is a drive connecting rod, the drive connecting rod can be an electric cylinder or a gas lever, and the rotation of the table baffle 4 is achieved by the extension and retraction of the gas lever. When the motor or drive connecting rod is used for active drive, a position sensor can be provided to detect the position of the table baffle 4 or the ironing arm baffle 5, and the drive can be stopped when the position is switched into place.

[0044] Furthermore, the present invention can incorporate sensors on the table and / or the ironing arm to automatically open the corresponding table baffle 4 or ironing arm baffle 5 when clothing is placed on the table or ironing arm. Since only one of the table or ironing arm is in use, when clothing is placed on the table, the sensor detects the presence of clothing, causing the table baffle 4 to open and the ironing arm baffle 5 to close, creating negative pressure on the table. Similarly, when clothing is placed on the ironing arm, the sensor detects the presence of clothing, causing the ironing arm baffle 5 to open and the table baffle 4 to close, creating negative pressure on the ironing arm. This achieves a level of automated operation.

[0045] Combine Figure 2 As shown, a bending section 61 for achieving elastic buffering is provided in the middle of the switching link 6. The switching link 6 is a flat plate structure with a bending section 61 formed in the middle. Therefore, the switching link 6 is not in the same plane. The bending section 61 can undergo elastic deformation, thereby avoiding impact when the table baffle 4 and the ironing arm baffle 5 move out of sync.

[0046] The table baffle 4 and / or the ironing arm baffle 5 are provided with elastic return elements, such as torsion springs disposed on the rotating shafts of the table baffle 4 and / or the ironing arm baffle 5. The elastic return elements are used to return the table baffle 4 or the ironing arm baffle 5 to a closed state. Depending on the frequency of use of the table and the ironing arm, one of them can be kept in a normally open state. For example, when the table is frequently used, the table baffle 4 can be kept in a normally open state, creating a negative pressure on the table. When the table is switched to the ironing arm baffle 5, the switching handle 7 is actively actuated. When the external force is released, the table baffle 4 automatically switches to the normally open state under the action of the elastic return element.

[0047] The present invention further provides a piano-style ironing table, comprising the above-mentioned tabletop air duct switching device. The piano-style ironing table can achieve the above-mentioned technical effects. For other parts of the ironing table structure, please refer to the existing technology, and the present invention will not repeat them here.

[0048] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
