Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a handheld ironing machine. Background Art

[0002] An iron is a household appliance used to smooth clothes and remove wrinkles. It can generate heat through the internal heating element, evaporate water and penetrate into the clothing fibers, soften the clothing and fabric fiber structure, and restore the clothes to a smooth and crisp appearance.

[0003] There are various types of existing irons, and the designs tend to be miniaturized and multifunctional. Among them, handheld irons are small in size and easy to store, which are suitable for daily clothing care at home.

[0004] When using a handheld iron, in order to ensure the ironing effect at the collar or cuffs, it is usually necessary to lay the clothes flat and make a hard pad under the ironing part of the clothes. The process is relatively cumbersome and it is not convenient for the user to temporarily handle the clothes he is wearing, which reduces the ironing efficiency of the iron for clothes. Utility Model Content

[0005] In order to improve the cumbersome process of ironing clothes and improve the ironing efficiency of clothes, the present application provides a handheld ironing device.

[0006] The present application provides a handheld ironing machine that adopts the following technical solution:

[0007] A handheld iron comprises an ironing head, a control handle and a lower clamping plate, wherein a rotating shaft structure is provided at one end of the ironing head, the ironing head is rotatably connected to the control handle via the rotating shaft structure, an end of the control handle away from the ironing head is rotatably connected to the lower clamping plate, the length of the lower clamping plate is equal to the sum of the lengths of the control handle and the ironing head, and the lower clamping plate abuts against the control handle and the ironing head.

[0008] By adopting the above technical solution, the ironing head is rotatably connected to the end of the control handle through the rotating shaft structure, and the ironing head can iron the clothes. The ironing head rotates on the control handle, so that the ironing head can iron the clothes with one side facing or away from the lower clamping plate. When the ironing surface of the ironing head faces the lower clamping plate, the lower clamping plate provides a rigid support for the clothes, which is convenient for the user to clamp and iron the collar and cuffs. When the ironing surface of the ironing head is away from the lower clamping plate, the ironing surface can release hot steam to the folds of the clothes, so that the clothes worn on the body can also be ironed. Through the rotational connection between the ironing head and the control handle, the handheld ironing device presents two ironing states, which improves the cumbersome problem of the clothes ironing process and improves the ironing efficiency of the clothes.

[0009] Furthermore, the rotating shaft structure includes a threaded rotating shaft, a nut and a bearing sleeve, the threaded rotating shaft is fixedly connected to the end of the ironing head, a connecting port is opened on the end of the control handle close to the ironing head, the nut is fixedly connected to the connecting port of the control handle, the threaded rotating shaft passes through the connecting port and is threadedly connected to the nut, and the bearing sleeve is arranged on the outer wall of the nut and is slidably connected to the nut.

[0010] By adopting the above technical solution, the threaded shaft is installed on the ironing head, the nut is installed in the connection port of the control handle, and the threaded shaft passes through the connection port and is threadedly connected with the nut, so that the ironing head and the control handle can rotate relative to each other. The bearing sleeve is arranged on the outer wall of the nut, and when the ironing head rotates on the control handle, the bearing sleeve and the nut slide relative to each other, so that the ironing head can rotate more smoothly, which is conducive to switching the ironing state of the handheld ironing device and improving the ironing efficiency of clothes.

[0011] Furthermore, the control handle includes an outer shell and a cover that are interlocked with each other, a first protrusion is arranged on the inner wall of the outer shell, a second protrusion symmetrical to the first protrusion is arranged on the inner wall of the cover, and the outer wall of the bearing sleeve is tightly pressed against the first protrusion and the second protrusion.

[0012] By adopting the above technical solution, the shell and the cover are interlocked to protect the components in the control handle. A first protrusion is provided on the inner wall of the shell, and a second protrusion is provided on the inner wall of the cover. When the shell and the cover are interlocked, the first protrusion and the second protrusion are symmetrically pressed against the outer wall of the bearing sleeve to fix the bearing sleeve, preventing the bearing sleeve from rotating with the nut, which is beneficial to improving the relative sliding smoothness between the bearing sleeve and the nut, facilitating the state switching of the handheld iron, and improving the ironing efficiency of clothes.

[0013] Furthermore, the outer ring of the threaded shaft is provided with an elastic filling component, and the elastic filling component is tightly pressed against the outer shell, the nut and the end of the bearing sleeve.

[0014] By adopting the above technical solution, the elastic filling component is pressed tightly between the inner wall of the shell and the end of the nut. The elastic filling component can increase the friction between the ironing head and the shell when the ironing head rotates. At the same time, it can also adjust the assembly gap between the ironing head and the control handle through elastic deformation, which facilitates the state switching of the handheld iron and improves the ironing efficiency of clothes.

[0015] Furthermore, the elastic filling component includes a spring and two symmetrically arranged spring brackets, and placement grooves for placing and retracting the spring are symmetrically opened between two opposite surfaces of the two spring brackets.

[0016] By adopting the above technical solution, the spring bracket is symmetrically arranged, and the spring is installed in the placement groove between the two springs. When the ironing head and the control handle move closer to or farther away from each other, the spring is compressed or stretched accordingly, thereby achieving the effect of filling the assembly gap, facilitating the state switching of the handheld iron and improving the ironing efficiency of clothes.

[0017] Furthermore, a connecting tube is integrally provided on the end surface of the ironing head close to the control handle, the threaded shaft is coaxially penetrated through the connecting tube and fixedly connected to the connecting tube, and the spring bracket is annularly arranged and abuts against the outer wall of the connecting tube.

[0018] By adopting the above technical solution, the setting of the connecting pipe is equivalent to increasing the contact area between the shell of the ironing head and the threaded shaft, preventing the threaded shaft and the ironing head from detaching from each other, thereby improving the stability of the ironing head when rotating on the control handle, facilitating the state switching of the handheld iron, and improving the ironing efficiency of clothes.

[0019] Furthermore, a rib is integrally provided on the end surface of the shell close to the ironing head, and the rib is located adjacent to the connecting port. A limiting groove for limiting the travel of the rib is provided on the end surface of the ironing head close to the control handle.

[0020] By adopting the above technical solution, a protruding rib is arranged on the end face of the ironing head, and a limiting groove is arranged on the end face of the control handle. After the protruding rib is inserted into the limiting groove, when the ironing head is rotated on the control handle, the stroke of the protruding rib is limited by the limiting groove, thereby limiting the maximum rotation stroke of the ironing head on the control handle and preventing the internal circuit from being damaged by twisting.

[0021] Furthermore, a spring sheet for popping open the lower clamping plate is provided on a side of the control handle close to the lower clamping plate, and the spring sheet is located on a side of the control handle away from the ironing head.

[0022] By adopting the above technical solution, the spring sheet is arranged between the control handle and the lower clamping plate, so that the lower clamping plate can be bounced open, thereby achieving the effect of clamping the ironing clothes between the ironing head and the lower clamping plate, which is beneficial to improving the ironing efficiency of clothes.

[0023] Furthermore, a cam is provided between the lower clamping plate and the control handle, the cam is rotatably connected to the lower clamping plate, and involutes for controlling the opening angle of the lower clamping plate are provided on both sides of the cam.

[0024] By adopting the above technical solution, the cam is rotatably connected to the lower clamping plate, and involutes are provided on both sides of the cam. The cam can limit the opening angle of the lower clamping plate through the involutes to prevent the lower clamping plate from being over-opened under the elastic action of the spring sheet.

[0025] Furthermore, the angle between the lower clamping plate and the control handle is an acute angle.

[0026] By adopting the above technical solution, the setting of the opening angle to the acute angle can avoid excessive opening and closing between the lower clamping plate and the operating wrench, which may cause burns due to accidental touch of the hand. At the same time, the collar or cuff of the clothing can be clamped between the ironing head and the lower clamping plate to ensure the ironing effect, which is conducive to improving the ironing efficiency of clothing.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The ironing head is rotatably connected to the end of the control handle via a rotating shaft structure. The ironing head can iron clothes. The ironing head rotates on the control handle so that the side of the ironing head that can iron clothes faces or faces away from the lower clamping plate. When the ironing surface of the ironing head faces the lower clamping plate, the lower clamping plate provides rigid support for the clothes, making it convenient for the user to clamp and iron the collar and cuffs. When the ironing surface of the ironing head faces away from the lower clamping plate, the ironing surface can release hot steam to the wrinkles of the clothes, so that the clothes worn on the body can also be ironed. Through the rotational connection between the ironing head and the control handle, the handheld iron presents two ironing states, which improves the cumbersome problem of ironing clothes and improves the ironing efficiency of clothes.

[0029] 2. The elastic filling component is pressed against the inner wall of the shell and the end of the nut. The elastic filling component can increase the friction between the ironing head and the shell when the ironing head rotates, and can also adjust the assembly gap between the ironing head and the control handle through elastic deformation.

[0038] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-6 And embodiments, the present application is further described in detail.

[0039] The present application discloses a handheld iron. The words such as "upper" and "lower" used to express the positional relationship in the present application are determined with reference to the placement and installation position of the handheld iron when it is in normal use. For example, the control handle 2 and the ironing head 1 are installed above the lower clamping plate 3, and the cover 23 of the control handle 2 is installed below the housing 22.

[0040] Reference Figure 1 and Figure 2 The handheld iron comprises an ironing head 1, a control handle 2 and a lower clamping plate 3. A rotating shaft structure 4 is provided at the end of the control handle 2 close to the ironing head 1, and the ironing head 1 is rotatably connected to the control handle 2 through the rotating shaft structure 4. The end of the control handle 2 away from the ironing head 1 is rotatably connected to the lower clamping plate 3. In this embodiment, the length of the lower clamping plate 3 is equal to the sum of the lengths of the control handle 2 and the ironing head 1, so that the lower clamping plate 3 provides a rigid support for the ironing head 1 behind the clothes.

[0041] Reference Figure 2 and Figure 3The control handle 2 includes a shell 22 and a cover 23 that are interlocked, and a shaft structure 4 and other components for controlling the iron are installed between the shell 22 and the cover 23. The shaft structure 4 includes a threaded shaft 41, a nut 42 and a bearing sleeve 43. A connecting pipe 11 is vertically fixedly connected to the end surface of the ironing head 1 close to the control handle 2. The threaded shaft 41 is inserted into the connecting pipe 11 and is fixed to the end of the ironing head 1 by clamping. A connecting port 21 for the threaded shaft 41 to pass through is opened on the end surface of the shell 22 close to the ironing head 1.

[0042] The nut 42 and the bearing sleeve 43 are both installed in the housing 22. The bearing sleeve 43 is annularly arranged on the outer wall of the nut 42 and is slidably connected to the nut 42. A first protrusion 221 is vertically and integrally arranged on the inner wall of the housing 22, and a second protrusion 231 is vertically and integrally arranged on the cover 23 at a position corresponding to the first protrusion 221. When the housing 22 and the cover 23 are buckled together, the first protrusion 221 and the second protrusion 231 on the outer wall of the bearing sleeve 43 are pressed and fixed.

[0043] An elastic filling component 44 for filling the assembly gap is provided on the outer wall of the connecting tube 11. The elastic filling component 44 includes two symmetrically arranged spring 441 brackets and a plurality of springs 441. The two spring 441 brackets are respectively in contact with the inner wall of the housing 22 and the bearing sleeve 43 on their opposite faces. The two opposite faces of the two spring 441 brackets are provided with an annular placement groove 4421 for the spring 441 to be placed and extended. In this embodiment, the number of springs 441 is preferably four. Each spring 441 is evenly circumferentially arranged in the placement groove 4421 and is perpendicular to the two spring 441 brackets. The ironing head 1 rotates on the control handle 2 through the rotating shaft structure 4 and moves closer or farther from each other. The spring 441 is compressed or stretched accordingly to fill the assembly gap between the housing 22 of the control handle 2 and the bearing sleeve 43.

[0044] Reference Figure 2 and Figure 4 A rib 222 is vertically and integrally provided on the end surface of the control handle 2 close to the ironing head 1, and a limiting groove 12 is provided on the end surface of the ironing head 1 for the rib 222 to be inserted into. The limiting groove 12 in this embodiment is semicircular and is arranged adjacent to the connecting pipe 11. When the ironing head 1 rotates on the control handle 2, the limiting groove 12 limits the maximum stroke of the rib 222, thereby limiting excessive rotation of the ironing head 1 and preventing torsional damage to the internal circuit.

[0045] Reference Figure 5 and Figure 6A spring sheet 24 is provided between the lower clamping plate 3 and the outer shell 22 of the control handle 2. The spring sheet 24 is clamped and fixed on the inner wall of the outer shell 22. The side of the spring sheet 24 away from the clamping with the outer shell 22 is pressed against the outer wall of the lower clamping plate 3, so that the lower clamping plate 3 can be opened. A cam 31 is rotatably connected to the end of the lower clamping plate 3. An involute 311 for controlling the opening angle of the lower clamping plate 3 is provided on both sides of the cam 31. A convex block 32 that cooperates with the cam 31 is provided on the outer shell 22 of the control handle 2. The end of the convex block 32 is pressed against the involute 311 to control the maximum opening angle of the lower clamping plate 3 to 15 degrees.

[0046] The implementation principle of a handheld iron in an embodiment of the present application is as follows: the rotational connection between the ironing head 1 and the control handle 2 enables the handheld iron to present two ironing states. The ironing head 1 and the control handle 2 are rotationally connected via a rotating shaft structure 4. The ironing head 1 rotates on the control handle 2 so that the side of the ironing head 1 that irons the clothes faces or faces away from the lower clamping plate 3. When the ironing surface of the ironing head 1 faces the lower clamping plate 3, the ironing head 1 and the lower clamping plate 3 clamp and iron the clothes. The lower clamping plate 3 provides rigid support for the clothes. The spring sheet 24 causes the lower clamping plate 3 to be ejected, making it easier for the user to clamp and iron the collar and cuffs. The cam 31 limits the maximum opening angle of the lower clamping plate 3 to an acute angle, preventing the lower clamping plate 3 from opening and closing excessively under the elastic action of the spring sheet 24, thereby preventing accidental touch of the hand and causing burns. Thus, the effect is achieved. When the ironing surface of the ironing head 1 is away from the lower clamping plate 3, the ironing surface can release hot steam to the wrinkles of the clothes, so that the clothes worn on the body can also be ironed. The protruding rib 222 on the end surface of the control handle 2 is limited by the limit groove 12 on the end surface of the ironing head 1, thereby limiting the maximum rotation stroke of the ironing head 1 on the control handle 2 to prevent the internal circuit from being damaged by twisting.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
