[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] It should be noted that when a component is referred to as being "mounted on", "fixed on" or "disposed on" another component, it may be directly on the other component or there may be a central component at the same time. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time.

[0030] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0031] See also Figures 1 to 5 The tension spring dial-type steam iron provided by the present invention comprises an iron body 1 and a handle 2, wherein the handle 2 is connected to the iron body 1 through a handle bracket 3, and a dial-type steam switch 4 is provided on the iron body 1, wherein the dial-type steam switch 4 comprises a tension spring 5, a tension connecting piece 6, a positioning stud assembly 7 and a switch assembly 8, wherein one end of the tension spring 5 is connected to the handle bracket 3, and the other end of the tension spring 5 is connected to one end of the tension connecting piece 6, and the other end of the tension connecting piece 6 is connected to one side of the switch assembly 8 through the positioning stud assembly 7.

[0032] When the steam needs to be turned on, the switch assembly 8 is toggled, and one end of the tension connecting piece 6 rotates synchronously with the switch assembly 8 with the rotation center of the switch assembly 8 as the fulcrum. At this time, the tension spring 5 connected to the tension connecting piece 6 is stretched as the tension connecting piece 6 rotates. When it is toggled to a preset angle, Figure 4 In the state shown, the tension spring 5, the tension connecting piece 6 and the force bearing points of the positioning stud 71 form a three-point straight line (such as Figure 4 The straight line 01 in FIG. 1 ) passes through the rotation center point of the switch assembly 8 (such as Figure 4 At this time, the steam is in the open state, and in this state, the force points of the tension spring 5, the tension connecting piece 6 and the positioning stud 71 have passed the central axis of the switch assembly 8 (that is, the rotation center of the switch assembly 8), and the tension spring 5 is in the stretched state. Under the action of the tension spring 5 (at this time, the tension of the tension spring 5 acts on Figure 4 When the steam source needs to be turned off, the switch assembly 8 can be turned in the reverse direction (i.e. clockwise) so that the force points of the positioning stud 71, the tension connecting piece 6 and the tension spring 5 are not in the same straight line (such as Figure 5The straight line 02 in the figure), due to the elastic force of the tension spring 5 being restored and reset, the switch assembly 8 is automatically reset, the steam source is turned off, and steam is saved. Through the toggle steam switch 4, the operator does not need to press the switch to control the steam flow state during the ironing process, which reduces labor intensity and improves ironing efficiency.

[0033] Specifically, a tension spring connecting seat 31 is welded on the handle bracket 3, one end of the tension spring 5 is connected to the handle bracket 3, and the height of the tension spring connecting seat 31 is adapted to the tension connecting piece 6, so that the force points of the tension spring 5, the tension connecting piece 6 and the positioning stud assembly 7 are on the same horizontal line, which is conducive to the positioning of the switch assembly 8 (i.e., positioning it in the open state).

[0034] In one embodiment, the tension spring connection seat 31 is L-shaped, one end of which is connected to the handle bracket 3, and the other end of which has a connection hole (not marked in the figure) for connecting the tension spring 5.

[0035] In another embodiment, the tension spring connecting seat 31 is irregularly L-shaped, one end of which is connected to the hand support 3, and the other end has an arc extending toward the switch assembly 8 for connection with the tension spring 5, so that the tension spring 5 does not interfere with the handle support 3, which is more conducive to positioning.

[0036] Please also read Figure 1 , Figure 2 and Figure 6 One end of the tension connecting piece 6 has a first connecting hole 61 for connecting the tension spring 5, and the other end of the tension connecting piece 6 has a second connecting hole 62 for inserting the positioning stud assembly 7. The middle part of the tension connecting piece 6 has a bow-shaped portion 63 for avoiding the switch assembly 8. Through the bow-shaped portion 63, when the switch assembly 8 is moved to a preset angle, it avoids contact or friction with the switch assembly 8 and cannot be positioned. The tension connecting piece 6 is in the shape of a bow as a whole, so that the switch assembly 8 can be positioned by being tightened by the tension spring when it is moved to the preset angle.

[0037] Please also read Figure 3 The switch assembly 8 includes a switch handle 81, a steam valve 82, a switch fixing member 83 and a switch rotating member 84. The switch fixing member 83 is connected to the iron body 1. The steam valve 82 is arranged in the switch fixing member 83. The switch rotating member 84 is connected to the switch fixing member 83 and abuts against the steam valve 82. The switch handle 81 is connected to the switch rotating member 84. By turning the switch handle 81, the switch rotating member 84 can be controlled to rotate synchronously. In the initial state, the steam valve 82 abuts against the switch rotating member 84, so that the steam valve 82 is in a closed state. When the steam valve 82 is reversed (such as Figure 1When the switch handle 81 is turned counterclockwise to make the switch rotating member 84 rotate in the reverse direction, a distance is created between the switch rotating member 84 and the steam valve 82. At this time, the steam valve 82 moves upward to an open state under the pressure of steam, so that steam can smoothly enter the iron body 1.

[0038] Please also read Figure 7 The switch handle 81 has a hand-operated portion 811 and a connecting portion 812, and the hand-operated portion 811 and the connecting portion 812 are integrally formed to improve the strength of the switch handle 81. One side of the connecting portion 812 has a protruding portion 813 for connecting the tension connecting piece 6, and the protruding portion 813 has a third connecting hole 814 for inserting the positioning stud assembly 7. The third connecting hole 814 is arranged at an angle of 45 degrees with the hand-operated portion 811, so that when the hand-operated portion 811 is reversely rotated 45 degrees, the connecting portion 812, the tension spring 5, and the tension connecting piece 6 are in a straight line (such as Figure 4 The line indicated by the number 01 in the figure), and the rotation center axis of the switch assembly (i.e., the center of the rotation axis 841) is located on the right side of the three-point line. At this time, the force of the tension spring is Figure 4 Furthermore, the end of the hand-operated portion 811 is tilted upward at a certain angle to reduce the distance between the hand-operated portion 811 and the handle 2, so that when the handle 2 is held, the switch handle 81 can be moved by extending a finger to facilitate operation.

[0039] In one embodiment, the hand-operated portion 811 is solid (eg Figure 2 , Figure 3 and Figure 7 As shown), for finger movement, in another embodiment, the hand-moving portion 811 is a ring-shaped portion (as shown Figure 1 , Figure 4 and Figure 5 As shown), it is suitable for people with shorter fingers. When turning, the ring part can be hooked with the fingers and turned. Both shapes are acceptable and can be selected according to actual needs. There is no restriction here.

[0040] Please continue reading Figures 1 to 5 The switch fixing component 83 includes a switch connecting seat 831, a threaded connector 832, a first sealing member 833 and a nut 835. One end of the threaded connector 832 is threadedly connected to the switch connecting seat 831, and the other end of the threaded connector 832 is connected to the nut 835. The first sealing member 833 is arranged between the threaded connector 832 and the switch connecting seat 831. The first sealing member 833 can prevent steam from leaking from the connection between the threaded connector 832 and the switch connecting seat 831 when the steam valve 82 is opened.

[0041] In the initial state, the rotation center axis of the switch assembly 8 (i.e., the center of the rotation axis 841, such as Figure 4Point A in the figure) is located on the left side of the line connecting the tension spring 5 and the positioning stud assembly 7 (such as Figure 5 The steam valve 82 seals the steam inlet hole of the switch connection seat 831. When the switch handle 81 controls the switch rotating member 84 to rotate in the opposite direction, the tension spring 5, the tension connecting piece 6 and the positioning stud 71 form a three-point straight line (such as Figure 4 The straight line 01 in FIG. 1 ) passes through the rotation center point of the switch assembly 8 (such as Figure 4 The switch rotating member 84 is moved up to a preset height (point A in FIG. 1 ) so that a gap is created between the switch rotating member 84 and the steam valve 82 so that steam can enter the iron body 1 .

[0042] The switch rotating component 84 includes a rotating shaft 841, a toothed positioning piece 842, a washer 844, a second seal 840, a third seal 843, a fourth seal 846 and a first screw 845. One end of the rotating shaft 841 is threadedly connected to the threaded connector 832. The washer 844 is sleeved on the rotating shaft 841 and placed in the inner hole of the threaded connector 832. The second seal 840 is sleeved on the rotating shaft 841 and placed on the washer 844. The third seal 843 is arranged between the second seal 840 and the washer 844. The fourth seal 846 is arranged between the second seal 840 and the nut 835. The toothed positioning piece 842 is sleeved on the rotating shaft 841. The first screw 845 is connected to the other end of the rotating shaft 841. The rotating shaft 841 is connected to the switch handle 81 through the first screw 845.

[0043] Specifically, the nut 835 has a through hole (not shown in the figure) for the rotating shaft 841 to extend out, and the fourth sealing member 846 seals the connection between the nut 835 and the rotating shaft 841 to prevent steam leakage.

[0044] The second sealing member 840 is in the shape of an upright bowl, with a slightly smaller end thereof sleeved on the rotating shaft 841 , and a slightly larger end thereof matching the inner diameter of the threaded connector 832 , thereby preventing steam from leaking from one end of the threaded connector 832 .

[0045] The present invention also uses the washer 844 to prevent the second seal 840 from rubbing against the internal thread of the threaded connector 832, thereby affecting its sealing performance. Moreover, the third seal 843 and the fourth seal 846 are respectively disposed at both ends of the second seal 840, so that when the nut is connected to the threaded connector 835, the second seal 840 is prevented from rubbing against the nut 835 and the washer 844, thereby ensuring its sealing performance.

[0046] The inner hole of the toothed positioning piece 842 is a square hole, and the other end of the rotating shaft 841 is adapted to the square hole, so that when the toothed positioning piece 842 rotates, the rotating shaft 841 can rotate synchronously.

[0047] Furthermore, the connection portion 812 of the handle 2 has an inner gear ring (not shown in the figure) adapted to the toothed positioning piece 842, and the toothed portion of the toothed positioning piece 842 meshes with the inner gear ring, so that when the switch handle 81 is rotated, the rotating shaft 841 is synchronously rotated. Compared with a rigid connection, this embodiment can achieve the purpose of labor saving, so that when the switch handle 81 is toggled, it does not require a lot of force to operate, reducing the labor intensity of the operator. At the same time, when resetting, only the switch handle 81 needs to be gently toggled to ensure that it can be reset by the tension of the tension spring 5.

[0048] Please also read Figure 8 The positioning stud assembly 7 includes a stud 71 and a second screw 72, the second screw 72 is connected to the stud 71, the stud 71 has a base 711 and a columnar portion 712, the base 711 is larger than the second connecting hole 62, the diameter of the columnar portion 712 is slightly smaller than the diameters of the second connecting hole 62 and the third connecting hole 814, and the length thereof is slightly larger than the distance between the protrusion 813 and the tension connecting piece 6. The second screw 72 is connected to the columnar portion 712, so that the tension connecting piece 6 can rotate freely without shaking to affect the positioning of the switch handle 81.

[0049] Please continue reading Figure 1 The tension spring pull type steam iron further comprises a hanging device (not shown in the figure), which is connected to one side of the handle bracket 3 through a hanging rod 32, and the end of the hanging rod 32 is connected to the tension stabilizer outside the iron. When the operator is not ironing, the hanging device is used to hang the iron body 1 through the hanging rod 32, so that the iron body 1 is separated from the object to be ironed (such as clothes, cloth, etc.) by a preset distance, which can prevent the iron body 1 from scalding the object to be ironed. During operation, the tension balancer outside the iron provides elastic force, so that the steam iron can be pulled back onto the cloth for ironing. Moreover, when the operator is ironing, the hanging device can also reduce the labor intensity of the operator. Specifically, the preset distance is 30-50 mm, which can avoid scalding the object to be ironed and facilitate the ironing operation.

[0050] In this embodiment, the suspension rod 32 is bent at a preset arc so that the force point at its end is located in the middle of the ironing body 1. When the hanging device lifts the ironing body 1 through the suspension rod 32, the ironing body 1 is parallel to the object to be ironed, thereby preventing the part of the ironing body 1 that is not lifted from being scalded.

[0051] The connection between the suspension rod 32 and the handle bracket is higher than the tension spring connection seat 31 to avoid interference therewith and affecting the tension spring 5.

[0052] like Figure 2 As shown, the handle 2 includes a handle 21, a screw 22, a handle inner rod 23, a front rubber plug 24, a rear rubber plug 25 and a fixing screw 26. The handle inner rod 23 is sleeved on the screw 22, and the handle 21 is sleeved outside the handle inner rod 23. The fixing screw 26 passes through the handle bracket 3 and is connected to the screw 22. The front rubber plug 24 and the rear rubber plug 25 are respectively arranged at the front and rear ends of the handle 21. The handle 21 has an arc-shaped portion suitable for the hand, so as to facilitate grasping and operation. The handle 21 is made of wood or plastic material, which plays a heat insulation role to prevent the handle from being hot during ironing.

[0053] The iron body 1 comprises a cover 11, a bottom plate 12, an upper shell 13 of a steam inlet chamber, a lower shell 14 of a steam outlet chamber and a steam inlet joint 15. The cover 11 is arranged outside the upper shell 13 of the steam inlet chamber, and the lower shell 14 of the steam outlet chamber is placed on the bottom plate 12. The cover 11 and the bottom plate 12 are covered so that the upper shell 13 of the steam inlet chamber and the lower shell 14 of the steam outlet chamber are covered to form an inner cavity for accommodating steam. The cover 11 and the bottom plate 12 play a role in heat preservation of the inner cavity, so as to avoid condensation water after steam enters the inner cavity and waste steam. The steam inlet joint 15 is arranged at the rear side of the cover 11 so that it does not affect the use of the operator after being connected to the steam input pipe.

[0054] In summary, the tension spring toggle steam iron provided by the present invention comprises an iron body and a handle, wherein the handle is connected to the iron body through a handle bracket, and a toggle steam switch is arranged on the iron body, wherein the toggle steam switch comprises a tension spring, a tension connecting piece, a positioning stud assembly and a switch assembly, wherein one end of the tension spring is connected to the handle bracket, the other end of the tension spring is connected to one end of the tension connecting piece, and the other end of the tension connecting piece is connected to one side of the switch assembly through the positioning stud assembly. When the steam needs to be turned on, the switch assembly is toggled, and the tension connecting piece rotates synchronously with the switch assembly. At this time, the tension spring connected to the tension connecting piece is stretched, and when it is toggled to a preset angle, the stress points of the tension spring, the tension connecting piece and the positioning stud form a three-point straight line, and the steam valve is in an open state. In this state, the stress points of the tension spring, the tension connecting piece and the positioning stud have passed the central axis of the switch assembly (i.e., the rotation center of the switch assembly), and the switch assembly is fixed in an open state under the action of the tension spring. When the steam source needs to be turned off, the switch assembly only needs to be toggled in the opposite direction so that the force points of the positioning stud, the tension connecting piece and the tension spring are not in the same straight line. The switch assembly is automatically reset by the force of the tension spring, thus turning off the steam source and saving steam.

[0055] The invention can realize automatic positioning when opened, and can automatically reset by lightly pushing in the reverse direction, so that the operator does not need to keep pressing with hands during the ironing process, thereby reducing labor intensity and improving ironing efficiency.

[0056] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the claims attached to the present invention.
