Abstract
Description
Technical Field
[0001] This invention pertains to garment ironing devices, specifically relating to an integrated housing and a handheld iron. Background Technology
[0002] Existing irons have internal components assembled into the head and handle based on the shell. Since the shell is a split structure, in addition to assembling the components with the shell, it is also necessary to assemble each shell separately. The assembly process is cumbersome and inefficient. After the shells are assembled together, the size of the joint seams is easily inconsistent, which reduces product quality. Moreover, the assembled shell has poor strength and is easily deformed and damaged. Summary of the Invention
[0003] This invention addresses the shortcomings of existing irons, such as low assembly efficiency, unstable product quality, poor shell strength, and susceptibility to deformation and damage caused by the split shell structure. It provides an integrated shell and a handheld iron.
[0004] To achieve the above objectives, the present invention provides an integrated housing comprising a handle housing and a head housing and a bottom housing located at the upper and lower ends of the handle housing, characterized in that: the head housing, handle housing, and bottom housing are an integrated structure; the head housing has a head receiving cavity; the front end of the head housing has a first opening penetrating the head receiving cavity; the handle housing has a handle receiving cavity; the upper end of the handle receiving cavity communicates with the head receiving cavity; the lower end of the handle housing has a second opening penetrating the handle receiving cavity; the head housing extends along a first axis; the handle housing extends along a second axis; the forward extension direction of the first axis and the downward extension direction of the second axis maintain a first angle, the first angle being 90°-135°.
[0005] This unibody housing can be integrally manufactured through injection molding or other methods, ensuring a neat shape, reducing product appearance defects, and providing high strength, making it resistant to deformation and damage. In particular, it facilitates modular assembly of components as a whole, with assembly into the head cavity via the first opening and the handle cavity via the second opening, improving assembly efficiency and enabling automated assembly. Specifically, since the head housing extends along the first axis and the handle housing extends along the second axis, and the forward extension direction of the first axis maintains a first angle (90°-135°) with the downward extension direction of the second axis, the head cavity and handle cavity can maintain a relative positional relationship, facilitating the assembly of components within these cavities.
[0006] Preferably, the inner diameter of the head receiving cavity gradually increases from back to front. This gives the first opening a larger diameter, which facilitates the assembly of modular components from the first opening into the head receiving cavity.
[0007] Preferably, the rear end of the head housing has a third opening that extends through the head receiving cavity and is adjacent to the upper end of the handle housing. This third opening facilitates wiring after the corresponding internal components are assembled into the head receiving cavity and the handle receiving cavity.
[0008] Preferably, the rear end of the head housing has a wall intersecting the first axis, and the third opening is located on the wall. This wall facilitates the securing of components within the head receiving cavity, ensuring a secure assembly.
[0009] Preferably, the head shell extends laterally and outward from the upper end of the handle shell relative to the handle shell, and the bottom extends laterally and outward from the lower end of the handle shell relative to the handle shell. Accordingly, while ensuring the handle shell is suitable for hand gripping, the head shell and bottom have a larger overall profile, making the product more suitable for ironing.
[0010] Preferably, the bottom has a coupling position for coupling iron parts such as the water tank.
[0011] In one embodiment, the coupling position is located on the upper side of the bottom and the front side of the second axis, and a fourth opening facing the coupling position is formed on the front wall of the lower part of the handle housing. The fourth opening communicates the coupling position with the handle receiving cavity, making it easy to couple and connect the structure inside the handle housing with the structure of the coupling position through the fourth opening.
[0012] In another embodiment, the coupling position is located on the lower side of the bottom, and the second opening is located within the outline of the coupling position. Accordingly, the second opening directly communicates the coupling position with the handle receiving cavity, facilitating the connection between the structure within the handle housing and the structure of the coupling part.
[0013] Preferably, the top surface and / or side surface of the head housing are provided with a first mounting through-hole that extends through the head receiving cavity. This first mounting through-hole facilitates the assembly of components for the head receiving cavity, or the assembly of functional components.
[0014] Preferably, the handle housing has a second mounting through hole that extends through the handle receiving cavity at a location near the head housing. This second mounting through hole facilitates the mounting of components for the handle receiving cavity, or the mounting of functional components.
[0015] The handheld iron of the present invention includes: One-piece housing; A first component, which is placed in and fixed in the head receiving cavity through a first opening, the first component includes at least a vaporization device. The second component is placed in and fixed in the handle receiving cavity through the second opening, and the second component includes at least a circuit board. The bottom surface, which is attached to the bottom, and the second axis maintains a second included angle with the bottom surface.
[0016] Accordingly, the components are modularized into a first component and a second component. The first component is assembled as a whole into the head receiving cavity through the first opening, and the second component is assembled into the handle receiving cavity through the second opening, improving assembly efficiency and facilitating automated assembly. Furthermore, the circuit board and the vaporization device are located in two separate receiving cavities at a suitable distance, preventing the circuit board from being affected by the heat from the vaporization device.
[0017] Preferably, the first component includes an ironing board with distributed steam holes. This improves the integration of the first component and the efficiency of assembly into the head receiving cavity.
[0018] Preferably, the first component includes an ironing surface and a suction device. The ironing surface includes an ironing board with steam holes distributed on it, and suction holes distributed on the ironing surface. The suction holes are connected to the suction device via air ducts. Accordingly, the assembly efficiency is improved while increasing the functionality of the iron.
[0019] Preferably, the inner diameter of the head receiving cavity gradually increases from back to front. This gives the first opening a larger diameter, facilitating the insertion of the first component into the head receiving cavity through the first opening.
[0020] Preferably, the rear end of the head housing has a third opening that extends through the head receiving cavity and is adjacent to the upper end of the handle housing, where a rear cover is fitted. This third opening facilitates wiring after the corresponding internal components are assembled in the head receiving cavity and the handle receiving cavity, and the wiring is concealed by the rear cover to ensure the product's neat appearance.
[0021] Preferably, the rear end of the head housing has a wall intersecting the first axis, the third opening is located on the wall, and the first component is fastened to the wall by fasteners. Accordingly, the first component can be reliably fixed and assembled into the head receiving cavity.
[0022] Preferably, the head shell extends laterally and outward from the upper end of the handle shell relative to the handle shell, and the bottom extends laterally and outward from the lower end of the handle shell relative to the handle shell. Accordingly, while ensuring the handle shell is suitable for hand gripping, the head shell and bottom have a larger overall profile, making the product more suitable for ironing.
[0023] Preferably, the bottom has a coupling point where the water tank is located, and the center of gravity of the entire handheld iron is located at the handle. Therefore, when using the iron by holding the handle, the burden on the grip is reduced, making it more comfortable for the user.
[0024] Preferably, the coupling position is located on the upper side of the bottom and the front side of the second axis, and a fourth opening facing the coupling position is formed on the front wall of the lower part of the handle housing. The fourth opening communicates the coupling position with the handle receiving cavity, facilitating the coupling of the second component inside the handle housing to the water tank at the coupling position. In particular, this structure facilitates placing the iron on a platform, placing the water tank at the coupling position, or removing the water tank from the coupling position, making operation convenient.
[0025] Preferably, the second axis is inclined forward relative to the bottom surface, and the second included angle is an acute angle greater than 60°. This structure positions the head housing and handle directly above the water tank, ensuring that the center of the entire iron is located at both the handle and the geometric center of the entire product, which facilitates comfortable grip and use by the user and ensures stability when the product is placed on a platform.
[0026] Preferably, the second component is fixed to the bottom with fasteners, and a bottom cover is mounted on the underside of the bottom, with the bottom surface located on the bottom cover. Before assembling the bottom cover, the exposed bottom facilitates assembly with the second component. After the second component is assembled, the bottom cover is then assembled to maintain the product's neat shape.
[0027] Preferably, the coupling position is located on the lower side of the bottom and the second opening is within the outline of the coupling position, with the bottom surface located at the bottom of the water tank. This increases the stability of the iron when placed.
[0028] Preferably, the second axis is perpendicular to the bottom surface, and the second included angle is 90°.
[0029] Preferably, the top surface and / or side surface of the head housing are provided with a first mounting through-hole that extends through the head receiving cavity, and the first mounting through-hole is provided with at least an exhaust vent. This first mounting through-hole facilitates the assembly of the first component into the head receiving cavity, or the assembly of functional components, such as the exhaust vent, through the first mounting through-hole.
[0030] Preferably, the handle housing has a second mounting through-hole extending through the handle receiving cavity near the head housing, and the second mounting through-hole is at least configured with a control element. This second mounting through-hole facilitates the assembly of a second component into the handle receiving cavity, or the assembly of a functional component.
[0031] Preferably, the second component includes a bracket and a circuit board and a water pump attached to the bracket, with the bracket fixedly assembled to the handle housing and / or the bottom. This ensures the neatness of the second component and ease of assembly.
[0032] This invention integrates the head shell, handle shell, and bottom into a single structure, ensuring a neat appearance, reducing product defects, and providing high strength, making it resistant to deformation and damage. Furthermore, the head shell has a head receiving cavity with a first opening at its front end, and the handle shell has a handle receiving cavity with its upper end communicating with the head receiving cavity. The lower end of the handle shell has a second opening communicating with the handle receiving cavity. This facilitates modular assembly of components as a whole, via the first opening into the head receiving cavity and via the second opening into the handle receiving cavity, improving assembly efficiency and enabling automated assembly. Since the head shell extends along a first axis and the handle shell extends along a second axis, and the forward extension direction of the first axis and the downward extension direction of the second axis maintain a first angle (90°-135°), the head receiving cavity and the handle receiving cavity can maintain a relative positional relationship, facilitating the assembly of components within these cavities.

Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0035] The terms “comprising” and “having”, and any variations thereof, used in the specification and claims of this invention are intended to cover a non-exclusive inclusion, such as a method or product that includes a series of technical features, not necessarily limited to those technical features explicitly listed, but may also include other technical features that may be included in the method or product but not explicitly listed.
[0036] In the description of this invention, it should be understood that the technical features defined by terms such as "first," "second," "third," and "fourth," which have a sequential concept, are only used to clearly describe the defined technical features and to clearly distinguish the defined technical features from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this invention.
[0037] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.
[0038] Example 1 Figure 1-5 The unibody housing of this embodiment is shown. Figure 6-10 The utilization of this embodiment is shown. Figure 1-5 The handheld iron shown is assembled from a single-piece housing.
[0039] Figure 1-5 The integrated housing 100 shown includes a handle housing 120 and a head housing 110 and a bottom housing 130 located at the upper and lower ends of the handle housing, respectively. The head housing 110, the handle housing 120, and the bottom housing 130 are an integrated structure. The head housing 110 has a head receiving cavity 111. The front end of the head housing 110 has a first opening 112 that passes through the head receiving cavity 111. The handle housing 120 has a handle receiving cavity 121. The upper end of the handle receiving cavity 121 communicates with the head receiving cavity 111. The lower end of the handle housing 120 has a second opening 122 that passes through the handle receiving cavity 121. The head housing 110 extends along a first axis 113, and the handle housing 120 extends along a second axis 123. The direction in which the first axis 113 extends forward and the direction in which the second axis 123 extends downward maintain a first angle α1, which is 90°-135°.
[0040] This unibody housing can be integrally manufactured using methods such as injection molding, ensuring a neat shape, reducing product appearance defects, and providing high strength, making it resistant to deformation and damage. In particular, it facilitates modular assembly of components as a whole, with assembly into the head cavity via the first opening and the handle cavity via the second opening, improving assembly efficiency and enabling automated assembly. Specifically, since the head housing extends along the first axis and the handle housing extends along the second axis, and the forward extension direction of the first axis maintains a first angle (90°-135°) with the downward extension direction of the second axis, the head cavity and handle cavity can maintain a relative positional relationship, facilitating the assembly of components within these cavities.
[0041] The above structure merely illustrates the basic concept of the integrated housing in this embodiment, enabling its realization. To further improve this technical solution, based on the above structure, any of the following preferred technical means or a combination of at least two technical means can be selected to obtain a better embodiment.
[0042] like Figure 1-5 As shown, the inner diameter of the head receiving cavity 111 gradually increases from back to front; that is, the profile of the cross-section of the head receiving cavity 111 perpendicular to the first axis 113 gradually increases from back to front. Furthermore, the profile of the cross-section of the head receiving cavity 111 perpendicular to the first axis is not limited to a circle. This allows the first opening to have a larger diameter, facilitating the assembly of modular components from the first opening into the head receiving cavity. Moreover, regarding the head shell, in... Figure 3 Along the first axis 113, the direction to the upper left is considered forward, and the direction to the lower right is considered backward; regarding the entire product, in Figure 3 The left side is the front, and the right side is the back.
[0043] like Figure 2 , Figure 5 As shown, the rear end of the head housing 110 has a third opening 114 that extends through the head receiving cavity 111 and is adjacent to the upper end of the handle housing 120. This third opening facilitates wiring after the corresponding internal components are assembled into the head receiving cavity and the handle receiving cavity.
[0044] like Figure 2 , Figure 5 As shown, the rear end of the head housing 110 has a wall 115 intersecting the first axis 113, and the third opening 114 is located on the wall 115. This wall facilitates the securing of components within the head receiving cavity, ensuring a firm assembly. The intersection of the first axis 113 and the wall 115 is intended to express the spatial relationship between the first axis and the wall, rather than a physical connection.
[0045] like Figure 3-4As shown, the head shell 110 extends laterally outward from the upper end of the handle shell 120 relative to the handle shell 120, and the bottom 130 extends laterally outward from the lower end of the handle shell 120 relative to the handle shell 120. "Extending laterally outward" means extending outward to at least one side of the handle shell. Accordingly, while ensuring the handle shell is suitable for hand gripping, the head shell and bottom have a relatively large external profile, making the product suitable for ironing.
[0046] like Figure 1 , Figure 3 As shown, the bottom 130 has a coupling position 131 for coupling iron components such as the water tank 600. Furthermore, the coupling position 131 is located on the upper side of the bottom 130 and the front side of the second axis 123. A fourth opening 124 facing the coupling position 131 is formed on the front wall of the lower part of the handle housing 120. The fourth opening 124 communicates the coupling position 131 with the handle receiving cavity 121, facilitating the coupling connection between the structure inside the handle housing and the structure of the coupling position.
[0047] like Figure 1 , Figure 4-5 As shown, the handle housing 120 has a second mounting through hole 125 that passes through the handle receiving cavity 111 near the head housing 110. This second mounting through hole facilitates the mounting of components of the handle receiving cavity, or the mounting of functional components such as the control component 802.
[0048] Handheld irons assembled based on the aforementioned one-piece shell, such as Figure 6-10 As shown, the handheld iron includes an integral housing 100, a first component 200, a second component 300, and a bottom surface 500.
[0049] The unibody housing 100 is as described above and will not be repeated here.
[0050] The first component 200 is placed in and fixed within the head receiving cavity 111 via the first opening 112. The first component 200 includes at least a vaporization device 201. The vaporization device 201 is used to convert water into steam. The vaporization device 201 includes a boiler, a thermostat, etc. In this embodiment, the first component 200 also includes an ironing plate 202 with distributed steam holes 203. This improves the integration of the first component and the efficiency of assembly into the head receiving cavity.
[0051] The second component 300 is placed in and fixed within the handle receiving cavity 121 via the second opening 122. The second component 300 includes a circuit board 301 and a water pump 303. The circuit board is used to control the operation of the iron; therefore, the power cord and electrical components such as the vaporization device, water pump, and control switch are directly or indirectly electrically connected to the circuit board. The connecting wires are omitted in the figure.
[0052] The bottom surface 500 is attached to the bottom 130, and the second axis 123 maintains a second included angle a2 with the bottom surface 500 to support the iron, that is, to place the iron on the platform.
[0053] Accordingly, some components are modularized into a first component and a second component. The first component is assembled as a whole into the head receiving cavity through the first opening, and the second component is assembled into the handle receiving cavity through the second opening, which improves assembly efficiency and facilitates automated assembly.
[0054] The above structure merely illustrates the basic concept of the handheld iron in this embodiment, enabling the handheld iron to be realized. To further improve this technical solution, based on the above structure, any of the following preferred technical means or a combination of at least two technical means can be selected to obtain a better embodiment.
[0055] like Figure 6-10 As shown, the inner diameter of the head receiving cavity 111 gradually increases from back to front. This results in the first opening having a larger diameter, which facilitates the insertion of the first component 200 into the head receiving cavity 111 through the first opening 122.
[0056] like Figure 6-10 As shown, the head housing 110 has a third opening 114 at its rear end, which extends through the head receiving cavity 111 and is adjacent to the upper end of the handle housing 120. A rear cover 400 is fitted at the third opening 114. This third opening 114 facilitates wiring after the corresponding internal components are assembled in the head receiving cavity 111 and the handle receiving cavity 121, and the wiring is concealed by the rear cover 400 to ensure the product's neat appearance. Furthermore, the rear end of the head housing 110 has a wall 115 intersecting the first axis 113, and the third opening 114 is located on the wall 115. The first component 200 is fastened to the wall 115 by fasteners. Accordingly, the first component can be reliably fixed and assembled in the head receiving cavity. In particular, the front part of the first component 200 contacts the front end of the head housing 110, positioning the first component relative to the head housing in the axial and circumferential directions of the first axis. Combined with the fasteners fastening the first component to the wall, the first component is reliably positioned and secured to the head housing, preventing loosening.
[0057] like Figure 6-10As shown, the head housing 110 extends laterally and outward from the upper end of the handle housing 120 relative to the handle housing, and the bottom 130 extends laterally and outward from the lower end of the handle housing relative to the handle housing. Accordingly, while ensuring the handle housing is comfortable to hold, the head housing and bottom have a relatively large overall profile, making the product suitable for ironing. For example, the ironing board 202 has an appropriate area, which improves ironing efficiency without increasing the weight of the iron and causing a burden on the grip. The water tank 600 in the bottom 130 also maintains an appropriate capacity, holding enough water to avoid frequent refills without overfilling and causing a burden on the user's grip.
[0058] like Figure 6-10 As shown, the bottom 130 has a coupling position 131, which houses the water tank 600. The center of gravity of the entire handheld iron is located at the handle. Therefore, when using the iron by holding the handle, the burden on the grip is reduced, making it more comfortable for the user.
[0059] like Figure 6-10 As shown, the coupling position 131 is located on the upper side of the bottom 130 and the front side of the second axis 123. A fourth opening 124 facing the coupling position 131 is formed on the front wall of the lower part of the handle housing 120. The fourth opening 124 connects the coupling position 131 with the handle receiving cavity 121, facilitating the coupling of the second component inside the handle housing with the water tank of the coupling position. In this embodiment, the connection is achieved through the interface 803 between the water valve 601 on the water tank and the second component. When the water tank is removed from the coupling position, the water valve of the water tank automatically closes to prevent leakage. When the water tank is placed in the coupling position, the water valve engages with the interface, and the water valve is opened by the interface, allowing the water stored in the water tank to be pumped to the vaporization device. In particular, this structure facilitates placing the iron on a platform and placing or removing the water tank from the coupling position, making operation convenient. Although the water tank is described here as detachable, in other embodiments, the water tank may be fixed to the coupling position and not detachable. In other embodiments, interface 803 may be assembled separately from the fourth port rather than as part of the second component.
[0060] like Figure 8 As shown, the second axis 123 is inclined forward relative to the bottom surface 500, and the second included angle a2 is an acute angle greater than 60°. This structure positions the head housing and handle directly above the water tank, ensuring that the center of the entire iron is located at both the handle and the geometric center of the entire product, which facilitates comfortable grip and use by the user and ensures stability when the product is placed on a platform.
[0061] like Figure 9-10As shown, the second component 300 is fixed to the bottom by fasteners, and a bottom cover 700 is mounted on the lower side of the bottom, with the bottom surface 500 located on the bottom cover 700. Before assembling the bottom cover, the exposed bottom facilitates assembly with the second component. After the second component is assembled in place, the bottom cover is then assembled, which conceals the assembly structure and maintains the neat shape of the product.
[0062] When ironing with the iron in this embodiment, hold the handle housing and press the control (switch button) with your hand. The water pump will then deliver the water stored in the water tank to the vaporization device through the water pipe. The vaporization device will convert the delivered water into steam, and the steam will be output from the steam holes on the ironing board. As the iron approaches and moves relative to the clothes, the steam will be applied to the clothes, thus performing the ironing function.
[0063] Example 2 Figure 11-15 The unibody housing of this embodiment is shown. Figure 16-20 The utilization of this embodiment is shown. Figure 11-15 The handheld iron shown is assembled with a one-piece housing. This embodiment of the handheld iron has more functions than Embodiment 1. Therefore, the product structure and the one-piece housing differ from Embodiment 1 in the following ways. In this embodiment, the same technical features as in Embodiment 1 are represented by the same reference numerals.
[0064] In this embodiment, the coupling position 131 is located below the bottom 130, and the second opening 124 is located within the outline of the coupling position 131. That is, when the water tank 600 is assembled on the coupling position 131, the water tank will cover the second opening. Therefore, after the water tank 600 is positioned on the coupling position 131, it is located at the very bottom of the entire iron, and the bottom surface 500 is located at the bottom of the water tank 600. The second axis 123 is perpendicular to the bottom surface 500, and the second included angle α2 is 90°. This increases the stability of the iron when it is placed. Furthermore, the second opening directly connects the coupling position to the handle receiving cavity, facilitating the connection between the structure inside the handle housing and the structure of the coupling part.
[0065] In this embodiment, the top and side surfaces of the head housing 110 are provided with first assembly through holes 116 that penetrate the head receiving cavity 111. The two symmetrical first assembly through holes 116 on the two side surfaces are equipped with exhaust holes 801. One first assembly through hole 116 on the top surface is used to assist in the assembly of the first component and is covered by a top cover 804 after assembly. This first assembly through hole facilitates the assembly of the first component into the head receiving cavity, or the assembly of functional components.
[0066] In this embodiment, the first component 200 includes an ironing surface and a suction device 204. The ironing surface includes an ironing board 202 with steam holes 203 distributed thereon and suction holes 205 distributed thereon. The suction holes 205 are connected to the suction device 204 via air ducts. This increases the functionality of the iron while also improving assembly efficiency. The ironing surface refers to the surface facing the clothes being ironed; therefore, it can be entirely the surface of the ironing board or larger than the surface of the ironing board.
[0067] In this embodiment, the second component 300 includes a bracket 320 and a circuit board 301 and a water pump 303 attached to the bracket. The bracket 302 is fixedly assembled with the handle housing and / or the bottom. This ensures the neatness of the second component and the ease of assembly.
[0068] In this embodiment, the control element is located on the upper end of the rear cover rather than the handle housing, therefore the second mounting through hole 125 is omitted compared to embodiment 1. Since the second opening 124 is located within the outline of the coupling position 131 in this embodiment, and the water tank is located below the coupling position, the fourth opening 124 is omitted compared to embodiment 1.
[0069] The other structures in this embodiment are the same as in Embodiment 1, and will not be described in detail.
[0070] When ironing with this iron, hold the handle and press the switch button. The water pump will then pump water from the tank to the vaporization device via a water pipe. The vaporization device converts the water into steam, which is then released from the steam holes on the ironing board. As the iron approaches and moves relative to the clothing, the steam is applied to the garment, thus ironing it. Because it is equipped with a suction device, suction holes, and an exhaust vent, the suction device is activated when steam is released. The suction holes draw air into the clothing, ensuring that the steam is fully applied to the garment without spilling out. The airflow generated by the suction device is finally exhausted from the casing through the exhaust vent.
[0071] The above embodiments illustrate the concept of integrating components into a single housing using first and second components. In practice, the composition of the first and second components can vary; the optimal approach is to integrate the most components. However, due to functional and structural requirements and limitations in the product's shape, individual parts may need to be assembled separately into the single housing. For example, the rear cover, bottom cover, water tank, interface, switch button, and air vent in the aforementioned embodiments are not integrated into the first and second components but are assembled separately.
