Technical Field

[0001] This utility model relates to the field of garment ironing technology, and in particular to an air duct switching device and a garment ironing table. Background Technology

[0002] Traditional garment ironing tables use mechanical air duct switching to switch between the table surface air duct and the ironing arm air duct. However, due to the suction velocity, according to Bernoulli's theorem, the air duct baffle during mechanical air duct switching is prone to tilting, resulting in weakened sealing, reduced negative pressure, affecting the ironing experience, and reducing efficiency.

[0003] Therefore, how to improve the phenomenon that the air duct baffle is prone to tilting is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] The frame is used to connect with the base plate of the garment ironing table to form a ventilation cavity that connects the table air duct and the ironing arm air duct.

[0007] The damper is rotatably connected to the frame via a pivot. The damper can rotate around the axis of the pivot to a horizontal state parallel to the bottom plate, a vertical state perpendicular to the bottom plate, and an inclined state between the horizontal and vertical states. In the horizontal state, the ventilation cavity is not connected to the table air duct, and in the vertical state, the ventilation cavity is not connected to the ironing arm air duct.

[0008] A drive unit, located inside the ventilation cavity, is used to drive the damper, which is in an inclined state, to rotate to a vertical state and keep the damper in a vertical state.

[0009] In one possible implementation, the frame includes two parallel and spaced first plates, the first plates being perpendicular to the axis of the rotating shaft, and each first plate having a first through hole at its top. The rotating shaft is rotatably inserted through the first through hole, and the damper is fixedly connected to the rotating shaft, with the center of gravity of the damper offset from the axis of the rotating shaft.

[0010] In one possible implementation, there are multiple dampers arranged at equal intervals within the ventilation cavity. Each damper corresponds to a rotating shaft, and when all dampers are in a horizontal state, adjacent dampers are connected and lie in the same plane. Each rotating shaft includes an extension, and all extensions extend to the same first plate on the side away from the ventilation cavity. A transmission component is connected to all extensions to drive all rotating shafts to rotate synchronously.

[0011] In one possible implementation, the driving element includes:

[0012] A baffle is located at the connection between the ventilation cavity and the heating arm air duct. The baffle is perpendicular to the bottom plate and fixed relative to the bottom plate. The baffle is provided with a second through hole, which is used to allow gas to flow between the ventilation cavity and the heating arm air duct.

[0013] The magnetic suction element is installed at the bottom of the baffle. It is used to magnetically attract the damper and rotate the damper to a vertical position.

The first connecting end is fixedly connected to all the second connecting plates, and the second connecting end is movable toward the first connecting end to drive the second connecting plates to move.

[0018] In one possible implementation, the first shaft body is provided with a fourth through hole, and a limiting member is provided through the fourth through hole to restrict the second connecting plate from disengaging from the first shaft body along the axial direction of the first shaft body.

[0019] In one possible implementation, the magnetic element is a magnet or a solenoid valve.

[0020] Based on the above, this application also provides a garment ironing table, including any of the air duct switching devices.

The air damper of the air duct switching device is rotatably connected to the frame via a rotating shaft. When the air damper rotates around the axis of the rotating shaft to a horizontal state parallel to the bottom plate, the ventilation cavity is only connected to the ironing arm air duct. When the air damper rotates around the axis of the rotating shaft to a vertical state perpendicular to the bottom plate, the ventilation cavity is only connected to the table air duct.

[0036] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0038] The purpose of this invention is to provide an air duct switching device and a garment ironing board that can improve the phenomenon that the air duct baffle is prone to tilting.

[0039] Please see Figures 1 to 5 To achieve the above objectives, this utility model provides an air duct switching device for switching between the table surface air duct and the ironing arm air duct 110 in a garment ironing table 100. The garment ironing table 100 is used for the final shaping treatment of sewn garments. The garment ironing table 100 typically includes two working surfaces: one is the surface of the worktable, and the other is the surface of the rocker arm set on the ironing table. The two working surfaces do not work simultaneously. The garment ironing table 100 is equipped with a centrifugal fan. The air path of the centrifugal fan is connected to the rocker arm surface through the ironing arm air duct 110 and to the surface of the worktable through the table surface air duct. The air duct switching device in the garment ironing table 100 enables the connection and disconnection of the ironing arm air duct 110 and the table surface air duct with the air path of the centrifugal fan, so that only one centrifugal fan is needed for the operation of both working surfaces. Compared with setting two centrifugal fans, this helps to reduce equipment costs.

[0040] The air duct switching device includes a frame 200, an air damper 300, and a drive unit 500. The frame 200 is connected to the base plate 120 of the ironing table 100 to form a ventilation cavity 210 connecting the table air duct and the ironing arm air duct 110. A ventilation hole 121 is provided on the base plate 120 of the ironing table 100. The airflow inlet of a centrifugal fan is connected to the ventilation hole 121 to draw away the gas in the ventilation cavity 210 to create a negative pressure environment and guide the gas flow in the table air duct and the ironing arm air duct 110. The air damper 300 is rotatably connected to the frame 200 via a rotating shaft 400. The air damper 300 can rotate around the axis of the rotating shaft 400 to a horizontal state parallel to the base plate 120, a vertical state perpendicular to the base plate 120, and an inclined state between the horizontal and vertical states. When the air damper 300 is in the horizontal state, the ventilation cavity 210 is only connected to the ironing arm air duct 110, and the ventilation cavity 210 is not connected to the table air duct. When the damper 300 is in a vertical position, the ventilation cavity 210 is only connected to the table air duct, and is not connected to the ironing arm air duct 110. It should be noted that in the prior art, the damper 300 switches to the vertical position by rotating around the axis of the rotating shaft 400 under its own gravity. After the damper 300 switches to the vertical position, there is no limit device to restrict the damper 300 from leaving the vertical position. When the ventilation cavity 210 is drawing air, according to Bernoulli's theorem, the damper 300 is prone to being tilted, so that the ventilation cavity 210 is simultaneously connected to the ironing arm air duct 110 and the table air duct, resulting in weakened sealing. In this embodiment, the air duct switching device is also provided with a driving component 500, which is disposed in the ventilation cavity 210. The driving component 500 is used to drive the damper 300, which is in a tilted position, to rotate to the vertical position and keep the damper 300 in a vertical position, thus restricting the damper 300 from leaving the vertical position.

[0041] The frame 200 of the air duct switching device is connected to the base plate 120 of the garment ironing table 100 to form a ventilation cavity 210. The air damper 300 of the air duct switching device is rotatably connected to the frame 200 via a rotating shaft 400. When the air damper 300 rotates around the axis of the rotating shaft 400 to a horizontal state parallel to the base plate 120, the ventilation cavity 210 is only connected to the ironing arm air duct 110; when the air damper 300 rotates around the axis of the rotating shaft 400 to a vertical state perpendicular to the base plate 120, ventilation... The cavity 210 is only connected to the tabletop air duct. The drive unit 500 of the air duct switching device is used to drive the damper 300, which is in a tilted state between a horizontal and a vertical state, to rotate to a vertical state and keep the damper 300 in a vertical state, unaffected by the negative pressure flow rate. This allows the damper 300 to close the ironing arm air duct 110, effectively improving the phenomenon that the air duct baffle 510 is easily tilted, ensuring the sealing of the ventilation cavity 210 when connected to the tabletop air duct, and improving the user experience.

[0042] In one possible implementation, the frame 200 includes two parallel and spaced-apart first plates 220 and a second plate connected to the two first plates 220. Both the first plates 220 and the second plate are perpendicular to the base plate 120, making the ventilation cavity 210 have an overall cuboid structure. The first plates 220 are perpendicular to the axis of the rotating shaft 400, and each first plate 220 has a first through hole at its top. The rotating shaft 400 is rotatably inserted through the first through hole. The damper 300 is fixedly connected to the rotating shaft 400, such that when the rotating shaft 400 rotates relative to the first through hole, the damper 300 and the rotating shaft... The 400 rotates synchronously, thereby adjusting the state of the damper 300 through the rotation of the shaft 400. The center of gravity of the damper 300 is off-center from the axis of the shaft 400, that is, the center of gravity of the damper 300 is not set on the axis of the shaft 400. This allows the damper 300 to rotate around the axis of the shaft 400 to a vertical state perpendicular to the base plate 120 under its own weight, without any other external interference. In other words, the vertical state is the usual state of the damper 300. During the process of the damper 300 rotating from the tilted state to the vertical state, the drive unit 500 can accelerate this process.

[0043] In one possible implementation, there are multiple dampers 300, which are arranged at equal intervals within the ventilation cavity 210. Each damper 300 corresponds to a rotating shaft 400. When all dampers 300 are in a horizontal state, adjacent dampers 300 are connected and lie on the same plane. The dampers 300 adopt a plate structure. When the dampers 300 are in a vertical state, the bottom of the damper 300 is in contact with the base plate 120 or has a small gap. Airflow channels are formed between adjacent dampers 300, and different channels are independent of each other, which can effectively reduce turbulence. These phenomena allow the air in the airflow channel to smoothly enter the centrifugal fan. The number of dampers 300 is preferably four, and the number of dampers 300 can be adjusted according to actual needs and circumstances, as long as the above purpose can be achieved. Each rotating shaft 400 includes an extension, and all extensions extend to the same first plate 220 on the side away from the ventilation cavity 210. The transmission component is connected to all extensions to drive all rotating shafts 400 to rotate synchronously, so as to ensure that all dampers 300 are in the same state, that is, the included angle between all dampers 300 and the base plate 120 is the same.

[0044] In one possible implementation, the drive unit 500 includes a baffle 510 and a magnetic attractor 520. The baffle 510 is located at the connection between the ventilation cavity 210 and the ironing arm air duct 110. The baffle 510 is perpendicular to the base plate 120 and fixed relative to the base plate 120. The baffle 510 is provided with a second through hole for gas to flow between the ventilation cavity 210 and the ironing arm air duct 110. The magnetic attractor 520 is installed at the bottom of the baffle 510. The magnetic attractor 520 is used to magnetically attract the air damper 300 and rotate the air damper 300 to a vertical state. The magnetic attractor 520 can be, but is not limited to, a magnet or a solenoid valve.

[0045] Understandably, one function of the baffle 510 is for the installation of the magnetic component 520. By stabilizing the position of the baffle 510 relative to the base plate 120, the position of the magnetic component 520 is also stabilized relative to the base plate 120, allowing the magnetic component 520 to magnetically attract the damper 300 and rotate the damper 300 to a vertical position. Another function of the baffle 510 is to limit the rotation range of the damper 300. When the damper 300 rotates from an inclined state to a vertical state, the baffle 510 prevents the damper 300 from rotating further in the direction of rotation after it reaches the vertical position. In addition, the baffle 510 can be configured to fit against the nearest vertically positioned damper 300.

[0046] In one possible implementation, the transmission component includes a first connecting plate 610 and a second connecting plate 620. The first connecting plate 610 includes a connecting plate 611 vertically connected to the extension and a first shaft 612 connected to the connecting plate 611. The second connecting plate 620 is provided with at least two third through holes for the first shaft 612 to pass through. The second connecting plate 620 can drive the first shaft 612 to move and rotate through the third through holes, so that the first connecting plate 610 drives the rotating shaft 400 to rotate around the axis of the rotating shaft 400.

[0047] The axis of the first shaft 612 is parallel to the axis of the rotating shaft 400. The connecting plate 611 is fixedly connected to the extension so that the extension rotates synchronously when the connecting plate 611 rotates. The connecting plate 611 is fixedly connected to the first shaft 612 to prevent the first shaft 612 from disengaging from the connecting plate 611 and to ensure the transmission effect of the first shaft 612. The third through hole on the second connecting plate 620 is used to rotatably connect with the first shaft 612, and the same second connecting plate 620 is used to rotatably connect at least two first shafts 612 so as to simultaneously drive at least two rotating shafts 400 to rotate synchronously.

[0048] In one possible implementation, the transmission component further includes a first connecting rod 630, which includes a first connecting end and a second connecting end. The first connecting end is fixedly connected to all the second connecting plates 620, and the second connecting end is movable toward the first connecting end to drive the second connecting plates 620 to move. A fourth through hole 613 is provided on the first shaft 612, and a limiting member is detachably inserted through the fourth through hole 613 to limit the second connecting plate 620 from disengaging from the first shaft 612 along the axial direction of the first shaft 612. The bottom of the rocker arm of the garment ironing table 100 is provided with a pushing member 111, and the second connecting end of the first connecting rod 630 is provided with an abutment plate 640. The abutment plate 640 and the pushing member... There is a gap between the components 111, and when the pusher 111 rotates with the rocker arm, the pusher 111 can contact the pusher 111 and push the first connecting rod 630 and the second connecting plate 620 to move toward the second connecting end. During this movement, the first connecting rod 630 and the second connecting plate 620 will move up and down synchronously to drive the first connecting plate 610 to rotate around the axis of the rotating shaft 400, so that the rotating shaft 400 drives the damper 300 to rotate to a horizontal state. When the rocker arm returns to its original position, the damper 300, under its own gravity, drives the rotating shaft 400 and the first connecting plate 610 to rotate back to a vertical state, and causes the second connecting plate 620 and the first connecting rod 630 to return to their original positions.

[0049] Based on the above, this application also provides a garment ironing table 100, including the aforementioned air duct switching device. The garment ironing table 100 further includes a centrifugal fan, an ironing arm air duct 110, and a tabletop air duct. The air path of the centrifugal fan is connected to the ventilation chamber 210 of the air duct switching device. Under the action of the damper 300 of the air duct switching device, the ventilation chamber 210 can selectively connect to the ironing arm air duct 110 and / or the tabletop air duct, so that one centrifugal fan can achieve air intake for both the ironing arm air duct 110 and the tabletop air duct, which helps to reduce equipment costs. In addition, the air duct switching device is provided with a drive component 500 for driving the damper 300, which is in an inclined state, to rotate to a vertical state, effectively improving the phenomenon that the air duct baffle 510 is prone to being in an inclined state, so as to ensure the sealing when the ventilation chamber 210 is connected to the tabletop air duct, thereby improving the user experience.

[0050] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0051] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
