Ironing device with interchangeable head positions

Abstract

This utility model discloses an ironing device with switchable head posture, belonging to the field of garment ironing technology. Existing handheld ironing devices require two hands to operate when changing working postures. This utility model addresses this by configuring an angle limiting structure between the head and the handle. This angle limiting structure restricts the head's rotation between a first position and a second position. An elastic force is also applied to the head to hold it in the first or second position. During the latter part of the head's rotation in one direction between the first and second positions, this elastic force assists the head in rotating to the first or second position. To change the head posture, the handle can be grasped, and the head can be pressed against an external object such as clothing or an ironing board to apply external force. This external force generates torque on the head, causing it to rotate and, with the help of the elastic force, rotate into and maintain the corresponding position. Therefore, only one hand is needed to switch the head posture, improving convenience.

Description

Technical Field

[0001] This utility model relates to clothing ironing technology, specifically to an ironing device with switchable head posture. Background Technology

[0002] The handheld ironing device is designed for users to hold and iron. For comfortable ironing and to improve ironing results, the ironing head can be rotated to change its position.

[0003] Earlier technical solutions, such as those disclosed in CN103334280B, CN101922106A, CN201648811U, and CN208762749U, all involve an ironing head that can rotate to change its posture. These patent documents all require the ironing head to be held and rotated while ironing, and the ironing head is hot during ironing, posing a risk of burns when rotating it.

[0004] Patent document CN119531115A discloses a handheld ironing device with a variable working posture. It includes a handle for gripping and an ironing head that rotates relative to the handle to change its working posture. The ironing head is connected to an actuator, which is spaced apart from the ironing head to prevent the hand from touching the ironing head when the actuator is operated to rotate it. During ironing, the actuator is operated to rotate the ironing head, preventing the hand from touching and getting burned. This handheld ironing device requires both hands to change its working posture, which is rather cumbersome. Utility Model Content

[0005] This invention addresses the shortcomings of existing handheld ironing devices that require two hands to operate when changing working postures, by providing an ironing device that allows switching head postures with only one hand, thereby increasing the convenience of switching head postures.

[0006] To achieve the above objectives, this utility model discloses an ironing device with a switchable head posture, comprising a handle for hand gripping and a head that can rotate relative to the handle to change its working posture under external force. Its key feature is that an angle-limiting structure is configured between the head and the handle, limiting the head's reciprocating rotation between a first position and a second position. An elastic force is also applied to the head to hold it in either the first or second position. During the latter part of the head's rotation in one direction between the first and second positions, this elastic force assists the head in rotating to the first or second position. To change the head posture, the handle can be gripped, and the head can be pressed against an external object such as clothing or an ironing board to apply external force. This external force generates torque on the head, causing it to rotate and, with the help of the elastic force, rotate into and maintain the corresponding position. Therefore, the head posture can be switched with only one hand, improving convenience.

[0007] The ironing device's ability to rotate its head against an object to change its posture is made possible by an angle-limiting structure and a spring. The angle-limiting structure determines the first or second position, while the spring helps hold the head in either position. Furthermore, during the latter part of the head's rotation in one direction between the first and second positions, the spring assists in turning the head to the first or second position. With the combined effect of the angle-limiting structure and the spring, the head can accurately rotate to and maintain the first and second positions, preventing it from either failing to rotate to the correct position or over-rotating.

[0008] In existing technologies, rotating the ironing head relies entirely on the hand continuously rotating it. However, if the head is pressed against an external object such as clothing or an ironing board to apply external force, it is difficult to rotate the head accurately into position, as is the method described in this invention.

[0009] The angle limiting structure of this utility model can prevent the head from rotating unrestricted relative to the handle, and prevent the wires and water pipes laid between the handle and the head from twisting and breaking.

[0010] Preferably, when the head rotates back and forth between the first and second positions, there is a critical position where the torque exerted by the elastic force on the head is 0. The latter part of the head's journey from the second position to the first position is the first latter part of the head's journey from the critical position to the first position, during which the elastic force exerts a first torque on the head, causing the head to rotate towards the first position. The latter part of the head's journey from the first position to the second position is the second latter part of the head's journey from the critical position to the second position, during which the elastic force exerts a second torque on the head, causing the head to rotate towards the second position. The first torque and the second torque are in opposite directions, and when the head is in either the first or the second position, the elastic force prevents the head from rotating to the other position. Accordingly, the rotation of the head and the elastic force it experiences change with the change in its rotational position, and the elastic force plays different roles during the rotation of the head.

[0011] Preferably, the elastic force is provided by an elastic element. An elastic element, such as various types of springs, can provide a sustained and suitable elastic force that can be overcome during the initial stroke of the shifting rotation, while also ensuring assistance and the force needed to hold the head in the first or second position.

[0012] Preferably, the head is mounted to a handle via a pivot, the pivot being connected to a lever, and the elastic force of an elastic element acts on the lever. Therefore, the elastic force applies a torque to the head via the lever, which prevents the head from rotating to another position. Moreover, during repositioning, this torque can also cause the head to rotate to the desired position.

[0013] In one embodiment, the elastic element is a tension spring, one end of which is connected to the handle and the other end acts on the rocker arm to apply an elastic tension force to the rocker arm. Tension springs are easy to materialize and offer flexible structural layouts.

[0014] Preferably, the other end of the tension spring is directly connected to the rocker arm. The structure is simple and compact.

[0015] Preferably, the other end of the tension spring is connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the swing arm. This avoids interference caused by the tension spring and the swing arm overlapping.

[0016] In another embodiment, the elastic element is a torsion spring, one end of which is connected to the handle and the other end acts on the pendulum to apply an elastic thrust to the pendulum.

[0017] Preferably, the handle includes a movable member, on which an adjusting member for adjusting the position of the movable member is connected, and one end of a tension spring is connected to the movable member. Accordingly, the tension of the tension spring can be adjusted as needed.

[0018] Preferably, the angle limiting structure includes two limiting posts located on the handle and the head, respectively, and a stop portion, with the stop portion positioned between the two limiting posts to limit the reciprocating rotation of the head. This structure is simple and compact, and does not affect the internal structure of the handle and the head.

[0019] This invention features an angle-limiting structure between the head and the handle, which restricts the head's rotation between a first position and a second position. An elastic force is also applied to the head to hold it in either position. During the latter part of the head's rotation in one direction between the first and second positions, this elastic force assists the head in reaching the first or second position. To change the head's posture, the handle can be gripped, and the head can be pressed against an external object such as clothing or an ironing board to apply external force. This external force generates torque on the head, causing it to rotate and, with the help of the elastic force, rotate into and maintain the desired position. Therefore, switching head postures can be done with just one hand, improving convenience. Attached Figure Description

[0042] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0043] Example 1

[0044] like Figure 1-2As shown, the ironing device with switchable head posture includes a handle 100 for hand gripping and a head 200 that can rotate relative to the handle to change its working posture when subjected to external force. An angle limiting structure is configured between the head 200 and the handle 100, which limits the head's reciprocating rotation between a first position p1 and a second position p2. An elastic force also acts on the head to hold it in the first or second position. During the latter part of the head's rotation in one direction between the first and second positions, this elastic force assists the head in rotating to the first or second position. To change the head posture, the handle can be gripped, and the head can be pressed against an external object such as clothing or an ironing board to apply external force. This external force generates torque on the head, causing it to rotate and, during the latter part of the rotation, is rotated into position and held in the corresponding position by the elastic force. Therefore, the head posture can be switched with only one hand, improving convenience.

[0045] The ironing device's ability to rotate its head against an object to change its posture is made possible by an angle-limiting structure and a spring. The angle-limiting structure determines the first or second position, while the spring helps hold the head in either position. Furthermore, during the latter part of the head's rotation in one direction between the first and second positions, the spring assists in turning the head to the first or second position. With the combined effect of the angle-limiting structure and the spring, the head can accurately rotate to and maintain the first and second positions, preventing it from either failing to rotate to the correct position or over-rotating.

[0046] In existing technologies, rotating the ironing head relies entirely on the hand (or even both hands) to continuously rotate it. However, if the ironing head is pressed against an external object such as clothing or an ironing board to apply external force, it is difficult to rotate the ironing head accurately.

[0047] The angle limiting structure of this utility model can prevent the head from rotating unrestricted relative to the handle, and prevent the wires and water pipes laid between the handle and the head from twisting and breaking.

[0048] This invention uses elasticity to position the head, which can prevent the head from becoming loose due to the gap between the head and the handle during rotational assembly.

[0049] like Figure 10-11 As shown, the head 200 has a critical position p0 when it reciprocates between the first position p1 and the second position p2. At this critical position, the direction of the elastic force passes through the center of the pivot 202, and the torque exerted by the elastic force on the head is 0. Figure 10-11 In the diagram, the solid line represents the actual location of the head, while the dashed line represents the location the head will switch to. The head starts from... Figure 11 The second position p2 shown is the turning point. Figure 10The latter part of the stroke of the first position p1 shown is the first subsequent stroke β1 of the head turning from the critical position p0 to the first position p1. In this first subsequent stroke β1, the elastic force applies a first torque to the head, causing the head to rotate towards the first position. The head from Figure 10 The first position p1 shown is the turning point. Figure 11 The latter part of the stroke of the second position p2 shown is the second subsequent stroke β2 of the head turning from the critical position to the second position. During this second subsequent stroke, the elastic force applies a second torque to the head, causing the head to rotate to the second position. The first torque and the second torque are in opposite directions. When the head is in either the first position or the second position, the elastic force prevents the head from rotating to the other position. Accordingly, the rotation of the head and the elastic force it experiences change with its rotational position, and the elastic force plays different roles during the rotation of the head.

[0050] like Figure 8-11 As shown, the elastic force is provided by the elastic element 510. The elastic element, such as various springs, can provide a sustained and suitable elastic force that can be overcome by external forces during the initial stroke of the shifting rotation, while also ensuring the force to assist and hold the head in the first or second position.

[0051] like Figure 3-7 As shown, the head 200 is assembled to the handle 100 via a pivot 202, which is connected to a rocker arm 520, allowing the head to be suspended from the handle by the rocker arm. The elastic force of the elastic element 510 acts on the rocker arm 20. Therefore, the elastic force of the elastic element 510 applies a torque to the head 200 through the rocker arm 520, which prevents the head from rotating to another position.

[0052] like Figure 8-11 As shown, the elastic element 510 is a tension spring. One end of the tension spring is connected to the handle 100, and the other end acts on the rocker arm 520 to apply an elastic tension to the rocker arm. The tension spring is easy to select materials for and allows for flexible structural layout. In the illustrated structure, the other end of the tension spring is connected to one end of the connecting rod 530, and the other end of the connecting rod 530 is rotatably connected to the rocker arm 520. This avoids interference caused by the tension spring overlapping with the rocker arm. Furthermore, the handle 100 includes a movable member 102, which is located below the water pump 600 and attached to the first inner frame 120. An adjusting member 103 for adjusting the position of the movable member is connected to the movable member 102. The adjusting member consists of two bolts, and one end of the tension spring is connected to the movable member 102. Tightening the two bolts from the front end of the handle adjusts the position of the movable member, thereby tightening or loosening the tension spring, thus allowing adjustment of the tension spring's elastic force as needed. In other embodiments, to simplify the structure, the other end of the tension spring is directly connected to the rocker arm.

[0053] like Figure 6-9As shown, the handle 100 includes the housing 110, the first inner frame 120 and the second inner frame 130. The first inner frame 120 and the second inner frame 130 are connected by snap-fit ​​or / and by fasteners to form an assembly. The assembly is also equipped with a water pump 600 and a position holding mechanism to form an integrated component. The integrated component is assembled with the housing to form the handle.

[0054] like Figure 8-9 As shown, the elastic element 510, the swing rod 520 and the connecting rod 530 are located between the first inner frame 120 and the second inner frame 130.

[0055] like Figure 6-7 As shown, the angle limiting structure includes two limiting posts 201 located on the handle 100 and the head 200 respectively, and a stop part 101. The stop part 101 is located between the two limiting posts 201 to limit the reciprocating rotation of the head. This structure is simple and compact and does not affect the internal structure of the handle and the head.

[0056] like Figure 10 As shown, the head 200, represented by the solid line, is located at the first position p1. The head 200 is blocked by the angle limiting structure and cannot rotate counterclockwise. The elastic tension of the tension spring applies a counterclockwise torque to the head, preventing the head from rotating clockwise towards the second position p2, represented by the dashed line. Therefore, the head is positioned at the first position.

[0057] like Figure 11 As shown, the head 200, represented by the solid line, is located in the second position p2. The head 200 cannot rotate clockwise due to the obstruction of the angle limiting structure. However, the elastic tension of the tension spring applies a clockwise torque to the head, preventing the head from rotating counterclockwise towards the first position p1, represented by the dashed line. Therefore, the head is positioned in the second position.

[0058] To move the head 200 from Figure 11 The second position shown Figure 10 When switching to the first position as shown, hold the handle and place your head against an external object such as clothing or an ironing board to apply external force to your head. This external force generates a counterclockwise torque on your head, causing it to rotate. Figure 11 As shown, the entire rotation stroke of the head is divided into a first forward stroke α1 and a first backward stroke β1. The first forward stroke α1 is the stroke from the second position p2 to the critical position p0. During the first forward stroke, the torque applied to the head by the elastic force is opposite to the direction of head rotation, thus preventing the head from turning away from the second position. Therefore, the torque generated by the head against the external object needs to be greater than the torque applied to the head by the elastic force to make the head rotate. The first backward stroke β1 is the stroke from the critical position p0 to the first position p1. During the first backward stroke, the direction of the torque generated by the elastic force changes to be consistent with the direction of head rotation. The torque generated by the elastic force helps the head quickly rotate to the first position and maintain the first position.

[0059] To move the head 200 from Figure 10 The first position shown is towards Figure 11 When switching to the second position, hold the handle and place your head against an external object such as clothing or an ironing board to apply external force to your head. This external force generates a clockwise torque on your head, causing it to rotate. Figure 10 As shown, the entire rotation stroke of the head is divided into a second front stroke α2 and a second rear stroke β2. The stroke from the first position p1 to the critical position p0 is the second front stroke α2. During the second front stroke, the torque applied to the head by the elastic force is opposite to the direction of head rotation, thus preventing the head from turning away from the first position. Therefore, the torque generated by the head against the external object needs to be greater than the torque applied to the head by the elastic force to make the head rotate. The stroke from the critical position p0 to the second position p2 is the second rear stroke β2. During the second rear stroke, the direction of the torque generated by the elastic force changes to be consistent with the direction of head rotation. The torque generated by the elastic force helps the head quickly rotate to the second position and maintain the second position.

[0060] It is known that ironing devices may or may not use steam to iron clothes. When this ironing device is in operation, the user presses the switch button 700, and the water pump 600 delivers water from a water tank located inside the handle or an external water tank to the vaporization device 203 in the head. The vaporization device 203 vaporizes the water into steam, which is then released from the head for ironing. In other embodiments, the vaporization device may be located inside the handle. Alternatively, ironing may not require steam, thus the water pump and vaporization device can be omitted.

[0061] Example 2

[0062] like Figure 12 As shown, the only difference between this embodiment and Embodiment 1 is the structural form of the elastic element 510. Specifically, in this embodiment, the elastic element 510 is a torsion spring, one end of which is connected to the first inner frame 120 of the handle, and the other end acts on the swing arm 520 to apply an elastic thrust to the swing arm.

[0063] In this embodiment, a movable member 102 and an adjusting member 103 can also be configured, and the spring force of the torsion spring can be adjusted by adjusting the position of the movable member through the adjusting member.

[0064] Figure 12 As shown, the head 200 is in the first position, where it cannot rotate counterclockwise due to the obstruction of the angle limiting structure. The elastic thrust of the torsion spring applies a counterclockwise torque to the head, preventing it from rotating clockwise to the second position. Therefore, the head is positioned in the first position.

[0065] As described in Example 1, when rotating between the first and second positions, the handle is held, and the head is pressed against an external object such as clothing or an ironing board to apply external force to the head. This external force generates torque on the head, causing it to rotate. Whether rotating from the first to the second position or from the second to the first position, in the initial stroke before reaching the critical position, the head rotation is resisted by the torque generated by the torsion spring. In the subsequent stroke after leaving the critical position, the torque generated by the torsion spring assists the head rotation and keeps the head in the first or second position.

[0066] exist Figure 12 In the diagram, the solid line represents the actual location of the head, while the dashed line represents the location to be switched to.

[0067] The remaining structure of this embodiment is the same as that of Embodiment 1, and will not be described in detail.
