Abstract
Description
Technical Field
[0001] This utility model relates to the field of ironing technology, and in particular to an air duct opening and closing mechanism and an ironing machine. Background Technology
[0002] Ironing is generally used for the final shaping of sewn garments. A typical ironing table consists of a platform covered with a cloth to absorb water. Internally, it houses a suction system, a blower, and a heating element. To better hold the garment against the ironing table, effectively evaporate the water generated during steam ironing, and assist in the ironing process, suction channels are incorporated into both the table surface and the ironing head. To save costs and reduce the overall weight of the machine, it is usually necessary to control the opening and closing of these suction channels to adjust the airflow. However, current suction channel control structures are complex, have poor stability, are prone to damage, and are difficult to repair. Utility Model Content
[0003] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides an air duct opening and closing mechanism and an ironing machine.
[0004] In a first aspect, this application provides an air duct opening and closing mechanism for controlling the opening or closing of the air duct of an ironing machine, the air duct opening and closing mechanism comprising:
[0005] The tabletop air duct is located on the side of the support platform away from the tabletop and is connected to the air duct of the ironing machine.
[0006] Multiple conversion plates are arranged along a first direction at the air outlet of the tabletop air duct, and the two ends of the conversion plates are rotatably connected to the inner side of the tabletop air duct.
[0007] The switching assembly includes a pull rod and a connecting frame. The connecting frame is located outside the tabletop air duct and is hinged to one end of each conversion plate that passes through the tabletop air duct. The pull rod is arranged along the first direction and is connected to the connecting frame at one end so as to pull the connecting frame to swing, thereby causing the conversion plate to flip at the air outlet of the tabletop air duct, thereby controlling the air volume of the tabletop air duct.
[0008] In one possible implementation, the switching assembly further includes a connecting strip, with connecting posts connected to both ends of the conversion plate. One end of the connecting post, away from the conversion plate, penetrates the inner side of the tabletop air duct and is hinged to one end of the connecting strip, while the other end of the connecting strip is hinged to the connecting frame.
[0009] In one possible implementation, the end of the pull rod extending toward the connecting frame is provided with a connecting thread, and the connecting frame is provided with a through hole, through which the threaded portion of the pull rod can be adjusted to pass.
[0010] In one possible implementation, the connecting frame has hinge holes spaced apart along the first direction on the side near the tabletop air duct, and the connecting strip is used to connect one end of the connecting frame to a rotating shaft, the rotating shaft extending rotatably into the hinge holes.
[0011] In one possible implementation, the switching assembly further includes an elastic element located on the outside of the tabletop air duct and on the same side as the connecting frame. One end of the elastic element is connected to the connecting frame, and the other end is connected to the frame of the ironing machine.
[0012] In one possible implementation, in the first direction, the connecting frame has an opening at one end near the elastic member, and one end of the elastic member is connected to the opening.
[0013] In one possible implementation, a handle is provided at the end of the pull rod away from the connecting frame, the handle being used to pull the pull rod to move in a first direction.
[0014] In one possible implementation, the length of the conversion plate is smaller than the diameter of the air outlet of the tabletop duct.
[0015] In one possible implementation, three conversion plates are provided, and when the three conversion plates are flipped to block the air outlet of the tabletop duct, the edges of adjacent conversion plates abut against each other.
[0016] Secondly, this application also provides an ironing machine, including the air duct opening and closing mechanism described in the above embodiments.
[0017] The technical solutions provided in this application have the following advantages compared with the prior art:
[0018] The system utilizes a tabletop air duct connected to the iron's air duct, directing hot air from the iron's duct to the tabletop air duct. Pulling a lever causes a connecting frame to swing, flipping a conversion plate at the tabletop air duct's outlet. This opens the outlet, allowing hot air to flow from the tabletop air duct towards the support table for ironing. To adjust the airflow, the lever can be used to swing the connecting frame, reducing the opening of the flip plate and decreasing the airflow towards the support table. In short, this air duct opening and closing mechanism cleverly uses a lever to swing the connecting frame, which in turn flips the conversion plate. This allows for both control of airflow volume and adjustment of hot air direction. The structure is simple, easy to operate, and convenient for maintenance. Attached Figure Description

Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0029] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0030] like Figure 1 As shown, this embodiment of the present invention provides an ironing machine, which includes a support platform 10, an air duct 30 disposed below the support platform 10, and an air duct opening and closing mechanism 20 for controlling the opening or closing of the air duct 30. In other words, this ironing machine, by setting the air duct opening and closing mechanism 20 at the air duct, controls the opening or closing of the air duct 30, thereby controlling the airflow and also changing the direction of the hot air to meet different ironing needs.
[0031] like Figures 2 to 6As shown, specifically, the air duct opening and closing mechanism 20 includes a tabletop air duct 21, a switching assembly, and multiple conversion plates 22. The tabletop air duct 21 is located on the side of the support platform 10 away from the tabletop and is connected to the air duct of the ironing machine. The multiple conversion plates 22 are arranged along a first direction at the air outlet of the tabletop air duct 21, and both ends of the conversion plates 22 are rotatably connected to the inner side of the tabletop air duct 21. The switching assembly includes a pull rod 26 and a connecting frame 27. The connecting frame 27 is located on the outside of the tabletop air duct 21, and the connecting frame 27 is hinged to one end of each conversion plate 22 that passes through the tabletop air duct 21. The pull rod 26 is arranged along the first direction, and the end of the pull rod 26 near the connecting frame 27 is connected to the connecting frame 27 to pull the connecting frame 27 to swing, thereby causing the conversion plates 22 to flip at the air outlet of the tabletop air duct 21, thereby controlling the air volume of the tabletop air duct 21.
[0032] The air duct opening and closing mechanism 20 of this embodiment connects the table air duct 21 to the air duct of the ironing machine, allowing hot air generated in the ironing machine's air duct to flow to the table air duct 21. Then, pulling the lever 26 drives the connecting frame 27 to swing, causing the conversion plate 22 to flip at the air outlet of the table air duct 21, opening the air outlet and allowing hot air to blow from the outlet of the table air duct 21 towards the support table 10, thus ironing the clothes placed on the support table 10. If the airflow needs to be changed, the lever 26 can be used to drive the connecting frame 27 to swing, reducing the opening of the flip plate and thus decreasing the airflow towards the support table 10. In other words, this air duct opening and closing mechanism 20 cleverly uses the lever 26 to drive the connecting frame 27 to swing, causing the conversion plate 22 to flip, achieving both control over the airflow and change of the hot air direction. It has a simple structure, is easy to operate, and facilitates subsequent maintenance.
[0033] It should be noted that the first direction defined above is for ease of describing the positional relationship between components. Specifically, the tabletop air duct 21 can be used as a reference. Here, the first direction X refers to the length direction of the tabletop air duct 21 (see [reference] for details). Figure 3 (in the X direction).
[0034] For example, the number of conversion plates 22 depends on the length of the countertop air duct 21. For instance, if the length of the air outlet of the countertop air duct 21 requires three conversion plates 22 to achieve complete coverage, then the number of conversion plates 22 is three.
[0035] Furthermore, the method of driving the lever 26 to move in the first direction can be manual or automatic using a power unit, and there is no limitation on this.
[0036] In one possible implementation, the switching assembly further includes a connecting strip 24. Connecting posts 23 are connected to both ends of the conversion plate 22. One end of the connecting post 23, away from the conversion plate 22, penetrates the inner side of the tabletop air duct 21 and is hinged to one end of the connecting strip 24. The other end of the connecting strip 24 is hinged to the connecting frame 27. In other words, by connecting the connecting posts 23 to both ends of the conversion plate 22, and connecting the connecting posts 23 through the inner side of the tabletop air duct 21 and connected to the connecting strip 24, with the other end of the connecting strip 24 hinged to the connecting frame 27, the linkage between the connecting frame 27 and the conversion plate 22 is achieved. This allows the conversion plate 22 to rotate within the tabletop air duct 21 when the pull rod 26 drives the connecting frame 27 to swing.
[0037] In one possible implementation, the end of the pull rod 26 extending towards the connecting bracket 27 is provided with a connecting thread 26a, and the connecting bracket 27 has a through hole 27b. The portion of the pull rod 26 with the connecting thread 26a can adjustably pass through the through hole 27b. Thus, the pull rod 26 can be rotated according to usage requirements, allowing the connecting thread 26a to adjustably pass through the through hole 27b, thereby achieving free adjustment of the connection length and enabling the structure to adapt to different working conditions or installation needs. Furthermore, the threaded connection requires no complex auxiliary tools; adjustment or disassembly can be completed simply by rotating the pull rod 26, reducing operational difficulty and time costs, and facilitating later maintenance or component replacement.
[0038] In one possible implementation, the connecting frame 27 has hinge holes 27a spaced along the first direction X on its side near the tabletop air duct 21. A connecting bar 24, used to connect the connecting frame 27, has a rotating shaft connected to one end, which rotatably extends into the hinge holes 27a. Thus, through the rotational engagement of the rotating shaft and the hinge holes 27a, the connecting bar 24 is allowed to rotate freely around the axis of the hinge holes 27a, thereby enabling the connecting frame 27 to swing while simultaneously causing the conversion plate 22 to flip.
[0039] In practical applications, if the lever 26 is not pulled, the conversion plate 22 will be in the normally open state. At this time, the air outlet of the table air duct 21 is open, and hot air is guided from the air outlet to the support table 10 for ironing. If it is necessary to adjust the air volume or switch the air direction, the lever 26 is pulled to drive the conversion plate 22 to flip, thereby changing the sealing area of the conversion plate 22 on the air outlet. Therefore, in one possible embodiment, the switching component also includes an elastic element 28. The elastic element 28 is located on the outside of the table air duct 21 and on the same side as the connecting frame 27. One end of the elastic element 28 is connected to the connecting frame 27, and the other end is connected to the frame of the ironing machine. That is to say, after the user releases the lever 26, the elastic element 28 drives the connecting frame 27 and the conversion plate 22 back to the initial position (i.e., normally open state) through the rebound force generated by the elastic deformation, avoiding manual reset operation and reducing the risk of misoperation. In addition, the flexible element 28 is arranged on the outside of the tabletop air duct 21, which can avoid occupying the internal space of the tabletop air duct 21, and can be replaced separately when damaged, without disassembling the core air duct, thus reducing maintenance costs and time.
[0040] In one possible implementation, in the first direction X, the connecting frame 27 has an opening 27c at one end near the elastic member 28, and one end of the elastic member 28 is connected to the opening 27c. That is, the opening 27c provided on the connecting frame 27 can precisely restrict the connecting end of the elastic member 28 to a specific position on the connecting frame 27, ensuring that the elastic force is transmitted along a predetermined direction (such as perpendicular to the axis of the connecting frame 27 or parallel to the first direction X), avoiding torque imbalance caused by connection point offset, and improving the efficiency of the elastic member 28 in exerting tension / compression on the connecting frame 27.
[0041] In one possible implementation, a handle 25 is provided at the end of the pull rod 26 away from the connecting frame 27. The handle 25 is used to pull the pull rod 26 to move in a first direction. In this way, the user can hold the handle 25 to pull the pull rod 26 to move in the first direction, which facilitates user operation.
[0042] To ensure that the conversion plate 22 is not interfered with during the flipping process within the countertop air duct 21, the length of the conversion plate 22 is smaller than the diameter of the air outlet of the countertop air duct 21.
[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
