Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to an ironing device. Background Technology

[0002] Adsorption steam irons are a new type of ironing equipment developed in the field of garment care to address the problem of ironing displacement caused by traditional ironing equipment. Its core function is to soften the wrinkles of clothes through steam penetration, while using the adsorption function to flatten and fix the clothes, avoiding displacement or secondary wrinkling during ironing, and greatly improving the flatness and efficiency of ironing. It is especially suitable for textiles with high precision requirements such as shirts and suits.

[0003] Existing adsorption steam irons typically include a main body, an ironing assembly, and a fan assembly. The fan assembly is fixedly integrated into the main body and forms a through-ventilation channel. One end of the channel is an adsorption vent facing the ironed item, while the other end connects to the outside. During operation, the fan assembly activates to create negative pressure at the adsorption vent, adsorbing and fixing the clothing. Combined with the softening effect of steam, this significantly reduces the difficulty of ironing.

[0004] However, the fan components of existing equipment are mostly fixed installation structures, which makes it impossible to flexibly adjust the airflow state, such as the magnitude of the adsorption force between the adsorption vent and the ironed object, the position of action, and the range of action. This makes it unable to adapt to the adsorption needs of different materials (such as thin silk and thick woolen fabric) and thick clothing, and it is also difficult to match the different ironing scenarios of small areas such as collars and cuffs and large areas such as the body of the garment. Ultimately, this limits the user experience and applicability of existing adsorption steam irons, making it difficult to meet the diverse ironing needs of users. Utility Model Content

[0005] This utility model provides an ironing device, the main purpose of which is to solve the problems existing in the prior art.

[0006] The present invention adopts the following technical solution: An ironing device includes a body, an ironing assembly, and a fan assembly. The fan assembly has an air duct, which includes a first vent that can be selectively used as an air outlet or an air inlet, and a second vent that cooperates with the first vent. The first vent is configured to face the object being ironed.

Detailed Implementation

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details.

[0029] Example 1: Reference Figure 1 and Figure 2 An ironing device includes a body 1, an ironing component 2, and a fan component 3. The fan component 3 has an air duct 321, which includes a first vent 322 that can be selectively used as an air outlet or an air inlet, and a second vent 323 that cooperates with the first vent 322. The first vent 322 is configured to face the object being ironed. In practical applications, the first vent 322 can be set as an air outlet or an air inlet according to the ironing needs of the specific device, or both functions can be retained simultaneously. The function can be easily switched by rotating the fan 31 in both directions, thereby effectively expanding the functional scenarios. For example, it can be set as an air inlet when it is necessary to fix the clothes, and switched as an air outlet when it is necessary to assist in shaping, drying steam, or removing wrinkles. In this embodiment, the adsorption function is prioritized, so the first vent 322 is set as an air inlet by default, fixing the clothes by negative pressure adsorption, while retaining the ability to switch functions to adapt to diverse needs.

[0030] Reference Figures 1 to 3 The fan assembly 3 has an adjustable mounting position. When in different mounting positions, the airflow interaction between the first vent 322 and the ironing object is different. The airflow interaction between the first vent 322 and the ironing object includes parameters such as the magnitude and location of the airflow. Changes in the airflow interaction can directly alter the airflow effect. Therefore, the multi-mounting position design can directly solve the core defect of the fixed airflow interaction state in existing adsorption steam irons. During use, different mounting positions can be flexibly switched according to specific needs to adjust the airflow effect, thereby adapting to different usage scenarios.

[0031] Reference Figures 1 to 3 There are many design schemes that can change the airflow effect by changing the installation position of the fan assembly 3. To facilitate easy implementation by those skilled in the art, this embodiment provides a core design concept: the body 1 is provided with an installation part, and the fan assembly 3 is rotatably or translatably mounted on the installation part to switch between different installation positions; when in different installation positions, the effective flow cross-section size of the air duct 321 is different or the spatial position of the first vent 322 is different. By changing the effective flow cross-section size of the air duct 321, the magnitude of the airflow effect between the first vent 322 and the ironing material can be changed, and by changing the spatial position of the first vent 322, the position of the airflow effect between the first vent 322 and the ironing material can be changed. Therefore, both schemes can achieve changes in the airflow state, thereby achieving different airflow effects.

[0032] Reference Figures 1 to 3As a preferred embodiment, this method adjusts the airflow effect by changing the effective cross-sectional size of the air duct 321. Specifically, the mounting part is a mounting groove 111 located in the body 1, and a ventilation grille 113 is provided in the mounting groove 111. The fan assembly 3 is rotatably mounted in the mounting groove 111, thereby aligning or misaligning the second ventilation opening 323 with the ventilation grille 113. The rotatable design allows for easy alignment or misalignment of the ventilation grille 113 with the second ventilation opening 323, thereby flexibly adjusting the opening of the second ventilation opening 323. This enables stepless adjustment of the cross-sectional size of the air duct 321, ultimately achieving adjustment of the adsorption force. This allows the adsorption force to be precisely adapted to different materials such as thin silk and heavy wool, avoiding damage or unstable fixation.

[0033] Reference Figures 1 to 3 More specifically, the body 1 includes a main body 11 and a handle 12. The main body 11 is provided with an installation cavity 112 and an installation groove 111 that are interconnected by a ventilation grille 113. The fan assembly 3 includes a fan 31 and a duct housing 32. The fan 31 is located in the installation cavity 112. The installation cavity 112 is provided with a fourth ventilation port (not shown in the figure) that is connected to the external environment. The duct housing 32 is provided with a duct 321 inside. The two ends of the duct housing 32 are a working end and an installation end, respectively. The working end is provided with a first ventilation port 322. The installation end is rotatably mounted in the installation groove 111 and is provided with a second ventilation port 323 that cooperates with the ventilation grille 113.

[0034] Reference Figures 1 to 3 During adsorption operation, the fan 31 operates, creating negative pressure within the duct 321. Gas enters the duct 321 through the first vent 322, then through the second vent 323 and the ventilation grille 113 into the mounting cavity 112, and finally exits through the fourth vent. When the adsorption force needs adjustment, the opening of the second vent 323 can be adjusted simply by rotating the duct housing 32, making operation simple and convenient. In this embodiment, the main body 11 of the machine body 1 is provided with independent mounting cavities 112 and mounting slots 111, thus providing conditions for the modular assembly of the fan 31 and the duct housing 32. The structural layout is reasonable and the assembly is convenient. At the same time, the independent rotation and adjustment of the duct housing 32 does not affect the working stability of the fan 31, ensuring reliable operation of the equipment during airflow adjustment.

[0035] Reference Figures 1 to 3 To prevent the duct housing 32 from coming off, a limiting structure can be set between the mounting groove 111 and the mounting end. For example, a limiting protrusion ring can be set on the outer side wall of the mounting end, and a limiting protrusion can be set on the inner side wall of the mounting groove 111. The mutually interlocking limiting protrusion ring and limiting protrusion can ensure that the duct housing 32 rotates stably in the mounting groove 111.

[0036] Reference Figure 2 and Figure 3 The ironing assembly 2 includes an ironing housing 21 and a steam generator 22 disposed within the ironing housing 21. The front end of the ironing housing 21 has an ironing panel 23 with a steam outlet, and the rear end of the ironing housing 21 is fixedly mounted in the middle of a mounting groove 111. The mounting groove 111 has a ventilation grille 113 on the outer periphery of the ironing housing 21. An air duct housing 32 is fitted onto the outside of the ironing housing 21 and rotatably connected to the mounting groove 111, allowing the second ventilation opening 323 to cooperate with the ventilation grille 113. This nested assembly of the air duct housing 32 and the ironing housing 21 effectively improves the utilization of equipment space and ensures the synergy between the first ventilation opening 322 and the ironing panel 23, enhancing the combined effect of steam ironing and airflow.

[0037] Reference Figure 2 and Figure 3 In this embodiment, the air duct housing 32 is a single-layer cylindrical structure. Both the front and rear ends of the air duct housing 32 are provided with connecting rings 324. The connecting rings 324 are provided with a first ventilation port 322 or a second ventilation port 323. The air duct housing 32 is sleeved on the outside of the ironing housing 21, and forms an air duct 321 for gas circulation between the air duct housing 21 and the ironing housing 21. This further optimizes the structure, reduces the size of the equipment, and reduces material costs.

[0038] Reference Figures 1 to 3 The machine body 1 also includes a water tank base 13, and a handle 12 connected between the main body 11 and the water tank base 13. The water tank base 13 stores water for use by the steam generator 22. The handle 12 contains components such as a water pump to achieve pipeline connection. Connecting the water tank base 13 to the main body 11 via the handle 12 makes the overall structure's center of gravity balanced, providing a stable grip and preventing tipping. Simultaneously, the independently designed water tank has a larger capacity and is easy to refill, which helps improve the machine's endurance. It should be noted that the specific structure and working principle of the ironing component 2 and the water tank are existing technologies and will not be described in detail here.

[0039] Example 2: Reference Figures 4 to 6 Unlike Embodiment 1, this embodiment adjusts the airflow effect by changing the spatial position of the first vent 322, thereby focusing on solving the problem of adapting the adsorption range of different ironing areas.

[0040] Reference Figures 4 to 6 Specifically, the installation part is a mounting slot 111 set in the body 1. The fan assembly 3 can be horizontally slidably assembled in the mounting slot 111 to adjust the horizontal distance between the first ventilation port 322 and the ironing object. This allows for precise adaptation to the different adsorption needs of small areas such as collars and cuffs and large areas such as the body of the garment, ensuring both precise local fixation and uniform overall coverage, thus significantly improving the applicability of the equipment.

[0041] Reference Figures 4 to 6 The body 1 includes a main body 11, a handle 12, and a water tank base 13. The main body 11 is provided with an installation cavity 112 and an installation groove 111 that are interconnected by a third ventilation port 114. The fan assembly 3 includes a fan 31 and a duct housing 32. The fan 31 is located in the installation cavity 112, and the installation cavity 112 is provided with a fourth ventilation port (not shown in the figure) that is connected to the external environment. The duct housing 32 is provided with a duct 321 inside. The two ends of the duct housing 32 are a working end and an installation end, respectively. The working end is provided with a first ventilation port 322, and the installation end is rotatably assembled in the installation groove 111 and is provided with a second ventilation port 323 that cooperates with the third ventilation port 114.

[0042] Reference Figures 4 to 6 During the adsorption operation, the fan 31 operates to generate negative pressure in the air duct 321. The gas enters the air duct 321 from the first vent 322, and then enters the mounting cavity 112 through the second vent 323 and the third vent 114, and finally exits from the fourth vent. When it is necessary to adjust the horizontal distance between the first vent 322 and the ironing object, it is only necessary to slide the air duct housing 32 horizontally in the front and back direction. The operation is simple and convenient.

[0043] Reference Figures 4 to 6 The sliding fit between the duct housing 32 and the mounting groove 111 can be flexibly designed according to requirements. As a preferred solution, this embodiment uses a threaded transmission structure to achieve the horizontal movement of the duct housing 32. That is, a mating thread (not shown in the figure) is provided between the mounting end and the mounting groove 111. By rotating the duct housing 32, it drives itself to move horizontally along the thread axis, thereby simplifying the internal design of the equipment. In order to limit the range of motion of the duct housing 32 and prevent it from falling out of the mounting groove 111, a limiting block or other blocking structure can also be designed between the mounting end and the mounting groove 111. Those skilled in the art can refer to conventional designs and implementations, and no limitation is made here.

[0044] Reference Figures 4 to 6 To ensure that the second vent 323 is always connected to the third vent when the air duct housing 32 is rotated to any angle, the rear end of the air duct housing 32 in this embodiment adopts an open structure, that is, the rear end of the air duct housing 32 is not provided with a connecting ring 324, but is an open design. When the air duct housing 32 is fitted outside the ironing housing 21, an air duct 321 is formed between the air duct housing 32 and the ironing housing 21. The second vent 323 is the annular outlet at the rear end of the air duct 321, ensuring smooth airflow.

[0045] Other structures in this embodiment (such as ironing component 2, water tank base 13, etc.) are the same as in embodiment one, and will not be described in detail here.

[0046] Example 3: Reference Figures 1 to 7 This embodiment combines the "adsorption force adjustment" of Embodiment 1 with the "horizontal position adjustment" of Embodiment 2 to form a steam iron with dual adjustment functions, further expanding the equipment's adaptability.

[0047] Reference Figure 7 The specific implementation of this embodiment is as follows: the mounting cavity 112 and mounting groove 111 of the main body 11 are provided with ventilation grilles 113; the mounting end of the air duct housing 32 is rotatably and horizontally mounted in the mounting groove 111. Multi-dimensional airflow adjustment is achieved through a combination of two movements: when the air duct housing 32 is rotated, the opening of the second ventilation opening 323 is adjusted by aligning or misaligning it with the ventilation grille 113, thereby adjusting the effective flow section of the air duct 321 (adapting to the adsorption force adjustment function of Embodiment 1); when the air duct housing 32 is moved horizontally, the horizontal position of the first ventilation opening 322 is changed, thereby changing the horizontal distance between the first ventilation opening 322 and the ironing object (adapting to the adsorption range adjustment function of Embodiment 2).

[0048] Reference Figure 7 In this embodiment, the threaded transmission structure in Example 2 is used to realize the horizontal movement of the air duct housing 32. That is, there is a mating thread between the mounting end and the mounting groove 111 (not shown in the figure). When the air duct housing 32 is rotated, it not only drives its horizontal movement, but also realizes the adjustment of the opening of the second ventilation port 323. No additional operation steps are required, simplifying the usage process.

[0049] Reference Figure 7 The second ventilation port 323 of the air duct housing 32 adopts the design scheme of Embodiment 1: the mounting end is provided with a connecting ring 324 with several second ventilation ports 323, to ensure that the alignment / misalignment effect of the second ventilation port 323 and the ventilation grille 113 is accurate during rotation adjustment, and to ensure the stability of the adsorption force adjustment.

[0050] Reference Figure 7 The dual adjustment function of this embodiment allows the steam iron to adapt to precise adsorption in small areas as well as uniform adsorption in large areas. At the same time, the adsorption force can be adjusted according to the material of the clothing, greatly expanding its applicability. It also features a compact structure and convenient operation.

[0051] The other structures in this embodiment (such as the body 1 and ironing components 2) are the same as in embodiments one and two, and will not be described again here.

[0052] Example 4: Reference Figure 8 and Figure 9 Unlike Embodiment 2, the mounting part is a slide groove 121 located on the body 1. The fan assembly 3 can be vertically slidably mounted on the slide groove 121. By adjusting the height of the first ventilation port 322, the interference avoidance function can be achieved, thereby enriching the application scenarios of the equipment.

[0053] Reference Figure 8 and Figure 9 Specifically, the machine body 1 includes a main body 11, a handle 12, and a water tank base 13. The main body 11 is equipped with an ironing component 2, and the handle 12 is provided with a slide groove 121 extending along the height direction. The fan component 3 can be vertically slidably mounted in the slide groove 121. By sliding it up and down to adjust the height of the first vent 322, the position of the airflow can be adjusted. This allows for flexible avoidance of raised decorations such as buttons, sequins, and embroidery on clothing, or three-dimensional parts such as shoulder lines and collars, preventing the first vent 322 from being blocked or jammed, ensuring smooth adsorption while protecting the clothing and the vent components.

[0054] Reference Figure 8 and Figure 9 The fan assembly 3 includes a duct housing 32 and a fan 31. The fan 31 is installed inside the duct housing 32, forming a duct 321 inside the duct housing 32. A first ventilation opening 322 is provided at the front end of the duct housing 321, and a second ventilation opening 323 (not shown in the figure) is provided on the side or rear end. To adjust the height of the first ventilation opening 322, the entire fan assembly 3 can be slid up and down along the slide groove 121. The sliding positioning of the fan assembly 3 can be achieved by adding a limiting structure (such as an elastic buckle, positioning pin, etc.), and the specific form is not limited.

[0055] Reference Figure 8 and Figure 9 The ironing assembly 2 includes an ironing housing 21 and a steam generator 22. In this embodiment, the structure can be simplified: the independent ironing housing 21 is omitted, and the steam generator 22 is directly placed inside the main body 11. The ironing panel 23 is fixed to the front end of the main body 11, thereby simplifying the assembly process and reducing the size of the equipment.

[0056] Reference Figure 8 and Figure 9 In practical applications, multiple mounting parts of different heights can be set on the handle. The fan assembly 3 adopts a detachable assembly, and users can flexibly choose the installation height according to their needs. When the adsorption operation is not required, the fan assembly 3 can be completely disassembled, thereby reducing the weight of the equipment and making it easy to carry and store.

[0057] Other functions of this embodiment (such as the ability of the first vent 322 to blow and suck, and the function of the water tank base 13) are the same as those of the embodiment, and will not be repeated here.

[0058] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
