Description

Technical Field

[0001] This application relates to the field of garment care technology, and more particularly to a vacuum iron. Background Technology

[0002] A vacuum iron can generate negative pressure suction and release high-temperature steam to achieve the function of adsorbing and ironing clothes or other fabrics.

[0003] In the prior art, a steam iron includes a panel, a housing, and a steam generating component, a suction component, and a control component disposed within the housing. The steam generating component supplies steam to the panel, and the suction component is disposed within the housing and communicates with an air intake on the panel to generate suction at the panel. The control component is disposed within the enclosed space formed by the housing to isolate it from the steam generating component and the suction component, preventing contact with moisture, and the control component is at least connected to the suction component to control its operation.

[0004] However, when using a vacuum cleaner, the heat generated by the control components cannot be dissipated, which can easily lead to overheating and damage to the control components. Utility Model Content

[0005] This application provides a vacuum ironing machine to solve the problem that the control components of existing vacuum ironing machines cannot dissipate heat, which can easily lead to overheating and damage of the control components.

[0006] The steam iron provided in this application includes:

[0007] The panel has a first air inlet.

[0008] The housing assembly has a panel covering it to form a mounting cavity together with the housing assembly. The mounting cavity has a first air inlet duct, a second air inlet duct, and an air outlet duct. The first air inlet is connected to the first air inlet duct. The housing assembly has a second air inlet, which is connected to the second air inlet duct.

[0009] The suction component is installed inside the mounting cavity. The air outlet duct is connected to the air outlet side of the suction component, and both the first air inlet duct and the second air inlet duct are connected to the air inlet side of the suction component.

[0010] The control component is located inside the second air inlet duct;

[0011] The suction unit is configured to guide outside gas into the air intake side through the first air intake duct and the second air intake duct, and to discharge it through the air outlet side and the air outlet duct.

[0012] Thus, the steam iron provided in this application includes a panel, a housing assembly, a suction component, and a control component. The panel and housing assembly form a mounting cavity with a first air inlet, a second air inlet, and an air outlet. A first air inlet communicating with the first air inlet is provided on the panel, and a second air inlet communicating with the second air inlet is provided on the housing assembly. The suction component and the control component are both located within the mounting cavity, with the control component specifically located within the second air inlet. The air inlet side of the suction component is connected to both the first and second air inlets, and the air outlet side of the suction component is connected to the air outlet. When the steam iron is running, the suction component can simultaneously draw in air from both the first and second air inlets and discharge it from the air outlet. The air flowing in the first air inlet can create a negative pressure at the first air inlet on the panel, allowing the steam iron to stably absorb clothing. The air flowing in the second air inlet can dissipate heat from the control component located within the second air inlet, preventing overheating and damage to the control component. Meanwhile, when the panel is in close contact with the clothing, the first air inlet is blocked, reducing the airflow in the first air intake duct. This increases the operating power of the suction component, causing it and the control components to generate more heat. However, the increased operating power of the suction component also allows more airflow into the second air intake duct, improving the heat dissipation of the control components and further ensuring overheat protection for them.

[0013] In one possible implementation, the steaming device provided in this application includes a housing assembly comprising a first housing, a panel covering the first housing, and a first air inlet located inside the first housing.

[0014] Thus, the first air inlet is formed inside the first housing. The shape and layout of the first air inlet can be rationally designed according to the structure of the first housing, so that the space utilization of the first air inlet is higher and the airflow flows smoothly in the first air inlet.

[0015] In one possible implementation, the steam iron provided in this application embodiment further includes a steam generating component, which is disposed in the first housing and connected to the panel;

[0016] The gap between the steam generating assembly and the first housing forms the first air inlet duct.

[0017] In this way, the gap between the steam generating component and the first housing serves as the first air inlet, avoiding the need to set up additional space for the air inlet and making the internal structure of the steamer more compact.

[0018] In one possible implementation, the steaming device provided in this application embodiment further includes a second housing, which is connected to the first housing. The second air inlet and the air outlet are both located inside the second housing, the suction component is disposed inside the air outlet, and the second air inlet is disposed on the second housing.

[0019] An air outlet is provided on the second housing, and the air outlet is connected to the air duct.

[0020] In this way, the space of each air duct is divided, which facilitates the layout of the air duct inside the shell, simplifies subsequent processing, reduces mutual interference between airflows, and improves the flow efficiency of airflow.

[0021] In one possible implementation, the steaming device provided in this application embodiment has a first mounting port on a first housing and a second mounting port on a second housing. The first mounting port and the second mounting port are connected so that the first air inlet duct communicates with the air inlet side through the first mounting port and the second mounting port.

[0022] This provides a smooth and unobstructed transition channel for the airflow in the first air inlet, enabling it to efficiently enter the air inlet side of the suction component from the first air inlet, reducing airflow resistance and turbulence at the connection point.

[0023] In one possible implementation, the steaming device provided in this application embodiment further includes a separator in the housing assembly. The separator is disposed in the second housing and divides the second housing to form a second air inlet duct and an air outlet duct.

[0024] A connecting port is provided on the separator, which connects the second air inlet duct and the air inlet side.

[0025] In this way, the separator divides the space inside the second housing to form a second air inlet and an air outlet, effectively avoiding mutual interference between the air inlet and outlet of the steamer, and making the airflow organization inside the second housing more orderly.

[0026] In one possible implementation, the steaming device provided in this application includes a second housing comprising a first sub-housing and a second sub-housing connected to each other, wherein the first sub-housing is connected to the first housing and the second sub-housing is connected to the first housing.

[0027] A separator is disposed within the first sub-shell to separate an air outlet duct and a portion of a second air inlet duct within the first sub-shell; the air outlet is disposed on the first sub-shell.

[0028] Another second air inlet is formed inside the second sub-housing. The second air inlet is located on the second sub-housing and on the side of the control assembly away from the air inlet side.

[0029] Thus, the split structure facilitates manufacturing, allowing the first and second sub-shells to be processed and assembled separately, improving production efficiency and ensuring a smooth airflow path for the second air inlet, reducing airflow resistance and energy loss.

[0030] In one possible implementation, the suction iron provided in this application embodiment has a first air inlet duct with a minimum cross-sectional area that is greater than the second air inlet duct with a minimum cross-sectional area.

[0031] In this way, sufficient negative pressure can be formed at the first air inlet of the panel, ensuring that the steam iron can stably absorb clothes. When the first air inlet is blocked, the air pressure and air speed of the second air inlet will also increase, thereby improving the heat dissipation effect on the control components.

[0032] In one possible implementation, the steaming device provided in this application embodiment further includes a heat dissipation component, which is disposed on the control component so that the control component dissipates heat through the heat dissipation component.

[0033] This increases the heat dissipation area of ​​the control components and improves heat dissipation efficiency.

[0034] In one possible implementation, the steaming machine provided in this application embodiment further includes a water tank assembly, which is disposed in the mounting cavity and communicates with the steam generating assembly.

[0035] In this way, a water source is continuously provided to the steam generating components, ensuring the continuous generation of steam.

[0036] In addition to the technical problems solved by this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that this application can solve, other technical features contained in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0047] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.

[0049] In the prior art, a steam iron includes a panel, a housing, and a steam generating component, a suction component, and a control component disposed within the housing. The steam generating component supplies steam to the panel, and the suction component is disposed within the housing and communicates with an air intake on the panel to generate suction at the panel. The control component is disposed within the enclosed space formed by the housing to isolate it from the steam generating component and the suction component, preventing contact with moisture. Furthermore, the control component is at least connected to the suction component to control its operation. The control component includes a circuit board and a metal-oxide-semiconductor field-effect transistor (MOS transistor) disposed on the circuit board. The MOS transistor is electrically connected to the suction component, which may specifically be a high-speed fan.

[0050] However, when using a vacuum cleaner, the high-speed fan operates at high power as the suction component, generating significant heat from the MOSFETs that control their operation. This heat cannot be dissipated, potentially leading to overheating and damage to the control components.

[0051] To overcome the deficiencies in the prior art, the steam iron provided in this application includes a panel, a housing assembly, a suction component, and a control component. The panel and housing assembly form a mounting cavity with a first air inlet, a second air inlet, and an air outlet. A first air inlet communicating with the first air inlet is provided on the panel. The suction component and the control component are both located within the mounting cavity, with the control component specifically located within the second air inlet. The air inlet side of the suction component is connected to both the first and second air inlets, and the air outlet side is connected to the air outlet. When the steam iron is running, the suction component can simultaneously draw in air from both the first and second air inlets and discharge it from the air outlet. The air flowing in the first air inlet can create a negative pressure at the first air inlet on the panel, allowing the steam iron to stably absorb clothing. The air flowing in the second air inlet can dissipate heat from the control component located within the second air inlet, preventing overheating and damage to the control component. Meanwhile, when the panel is in close contact with the clothing, the first air inlet is blocked, reducing the airflow in the first air intake duct. This increases the operating power of the suction component, causing it and the control components to generate more heat. However, the increased operating power of the suction component also allows more airflow into the second air intake duct, improving the heat dissipation of the control components and further ensuring overheat protection for them.

[0052] To facilitate understanding, the application scenarios of the embodiments of this application will be described first.

[0053] The term "clothing" to be ironed by the steam iron should be interpreted broadly, including but not limited to clothing, trousers, and other items worn on the body. It may also include fabrics such as curtains, sheets, and duvet covers. This application does not specifically limit this, and will be referred to as "clothing" below without further specific examples.

[0054] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0055] Reference Figure 1 and Figure 2 As shown in the embodiment of this application, the steam iron includes:

[0056] Panel 100, with a first air inlet 110 on panel 100;

[0057] The housing assembly 200 has a panel 100 covering it to form a mounting cavity 201 together with the housing assembly 200. The mounting cavity 201 has a first air inlet duct 211, a second air inlet duct 2221 and an air outlet duct 2211. The first air inlet 110 is connected to the first air inlet duct 211. The housing assembly 200 is provided with a second air inlet 2222, which is connected to the second air inlet duct 2221.

[0058] The suction component 300 is disposed in the mounting cavity 201. The air outlet duct 2211 is connected to the air outlet side of the suction component 300. The first air inlet duct 211 and the second air inlet duct 2221 are both connected to the air inlet side of the suction component 300.

[0059] Control component 400 is disposed within the second air inlet duct 2221;

[0060] The suction unit 300 is configured to guide outside gas into the air intake side through the first air intake duct 211 and the second air intake duct 2221, and discharge it through the air outlet side and the air outlet duct 2211.

[0061] It is understandable that the housing assembly 200 and the panel 100 together enclose the mounting cavity 201, providing installation space and protection for other components of the steamer, and preventing internal components from being impacted or damaged by external forces.

[0062] By configuring the internal structure of the housing assembly 200, a first air inlet duct 211, a second air inlet duct 2221, and an air outlet duct 2211 can be formed in the mounting cavity 201. Thus, the first air inlet duct 211 and the second air inlet duct 2221 are both connected to the air outlet duct 2211, forming a path for gas flow in the mounting cavity 201.

[0063] The panel 100 is used to contact clothing when the steam iron is running. A first air inlet 110 is provided on the panel 100 so that some external airflow can enter the first air inlet duct 211 through the first air inlet 110 to achieve effective adsorption of clothing.

[0064] The suction component 300 serves as the power element for gas circulation within the steam vacuum cleaner. Both the first air inlet duct 211 and the second air inlet duct 2221 are connected to the air inlet side of the suction component 300, and the air outlet side of the suction component 300 is connected to the air outlet duct 2211. When the steam vacuum cleaner is running, the suction component 300 generates suction, drawing external gas from the first air inlet duct 211 and the second air inlet duct 2221 into their air inlet sides, then expelling the gas from the air outlet side, and finally through the air outlet duct 2211 to the outside, thus achieving gas circulation.

[0065] A control component 400 is disposed within the second air inlet duct 2221 and is electrically connected to at least the suction component 300, thereby controlling the operating power of the suction component. The control component 400 mainly includes a circuit board and a MOSFET mounted on the circuit board. The MOSFET enables power control of the suction component 300, ensuring that the heat of the control component 400 is primarily generated by the MOSFET. When airflow occurs within the second air inlet duct 2221, the airflow can exchange heat with the control component 400 within the second air inlet duct 2221, allowing the heat generated by the control component 400 to dissipate with the airflow.

[0066] Therefore, the steaming device provided in this application includes a panel 100, a housing assembly 200, a suction component 300, and a control component 400. The panel 100 and the housing assembly 200 form a mounting cavity 201 having a first air inlet 211, a second air inlet 2221, and an air outlet 2211. A first air inlet 110 communicating with the first air inlet 211 is provided on the panel 100. The suction component 300 and the control component 400 are both located within the mounting cavity 201, and the control component 400 is specifically located within the second air inlet 2221. The air inlet side of the suction component 300 is connected to the first air inlet 211 and the second air inlet 2221, and the air outlet side of the suction component 300 is connected to the air outlet 2211. When the steaming device is running, the suction component can simultaneously draw in air from the first air inlet 211 and the second air inlet 2221 and discharge it from the air outlet 2211. The gas flowing through the first air inlet 211 creates a negative pressure at the first air inlet 110 of the panel 100, allowing the steam iron to stably absorb clothing. The gas flowing through the second air inlet 2221 dissipates heat from the control component 400 located within it, preventing overheating and damage. Simultaneously, when the panel 100 is in close contact with clothing, the first air inlet 110 becomes blocked, reducing the airflow in the first air inlet 211. This increases the operating power of the suction component 300, leading to more heat generation in both the suction component 300 and the control component 400. However, the increased operating power of the suction component 300 also allows more airflow into the second air inlet 2221, improving heat dissipation for the control component 400 and further ensuring overheat protection.

[0067] Reference Figure 1 and Figure 2 As shown, the housing assembly 200 includes a first housing 210, a panel 100 covering the first housing 210, and a first air inlet 211 located inside the first housing 210.

[0068] The panel 100 covers the first housing 210, specifically allowing the cover to be sealed to the first housing 210, forming a relatively enclosed space, which helps improve the overall sealing of the steam iron. This ensures that the gas at the first air inlet 110 can flow stably within the first air inlet duct 211 without leakage, improving airflow utilization efficiency and making the steam iron's performance more stable. Simultaneously, the first air inlet duct 211 is formed within the first housing 210, and its shape and layout can be rationally designed according to the structure of the first housing 210, maximizing space utilization and ensuring smooth airflow within it. This reduces airflow resistance and turbulence, improves gas flow efficiency, and enhances the suction power of the steam iron.

[0069] Furthermore, the space formed by the panel 100 and the first housing 210 can also be used to install components inside the steaming machine that are close to the panel 100, so as to make the steaming machine structure more compact.

[0070] Furthermore, refer to Figure 1 and Figure 2 As shown, the steam iron also includes a steam generating assembly 500, which is disposed inside the first housing 210 and connected to the panel 100;

[0071] The gap between the steam generating assembly 500 and the first housing 210 forms the first air inlet duct 211.

[0072] A steam generating assembly 500 is installed within the space-constrained first housing 210, with a gap between the outer side of the steam generating assembly 500 and the inner side of the first housing 210. This gap serves as the first air inlet 211, avoiding the need for additional space to be allocated for the first air inlet 211, thus making the internal structure of the steamer more compact. This helps to reduce the overall size of the steamer, making it easier to carry and store.

[0073] The steam generating assembly 500 is connected to the panel 100 and is located inside the first housing 210. Both the panel 100 and the first housing 210 provide reliable support for the steam generating assembly 500, reducing its shaking and displacement during operation, thereby increasing the installation stability of the steam generating assembly 500.

[0074] Reference Figure 1 and Figure 2 As shown, the housing assembly 200 also includes a second housing 220, which is connected to the first housing 210. The second air inlet duct 2221 and the air outlet duct 2211 are both located inside the second housing 220. The suction component 300 is disposed inside the air outlet duct 2211, and the second air inlet 2222 is disposed on the second housing 220.

[0075] An air outlet 2212 is provided on the second housing 220, and the air outlet 2212 is connected to the air outlet 2211.

[0076] It is understandable that the second housing 220 is connected to the side of the first housing 210 away from the panel 100, and a second air inlet duct 2221 and an air outlet duct 2211 are formed in the second housing 220, which realizes the spatial division of each air duct, facilitates the air duct layout inside the housing, and simplifies subsequent processing.

[0077] The second air inlet duct 2221 and the air outlet duct 2211 are independently arranged within the second housing 220, making the airflow path clearer and more reasonable. Specifically, the second housing 220 is provided with a second air inlet 2222 communicating with the first air inlet duct 211, and an air outlet 2212 communicating with the air outlet duct 2211. This allows outside air to directly enter the second air inlet duct 2221 through the second air inlet 2222, and then be discharged sequentially through the air outlet duct 2211 and the air outlet 2212 by the suction component 300, reducing mutual interference between airflows and improving airflow efficiency.

[0078] The suction component 300 is housed within the air outlet duct 2211, simplifying its installation. The suction component 300 only needs to have its outlet side facing the air outlet 2212 of the air outlet duct 2211, and its inlet side facing the first air inlet duct 211 and the second air inlet duct 2221. Furthermore, the outer wall of the suction component 300 must be in contact with the inner wall of the air outlet duct 2211. This ensures that both the first and second air inlets 211 connect to the air outlet duct 2211 via the suction component 300, guaranteeing its suction effect. Simultaneously, the independent air outlet duct 2211 ensures a relatively stable airflow environment around the suction component 300, reducing the impact of airflow turbulence on its operation and extending its service life.

[0079] In some embodiments, refer to Figure 1 and Figure 2 As shown, a first mounting port 212 is provided on the first housing 210, and a second mounting port 2213 is provided on the second housing 220. The first mounting port 212 and the second mounting port 2213 are connected so that the first air inlet duct 211 is connected to the air inlet side through the first mounting port 212 and the second mounting port 2213.

[0080] The first housing 210 and the second housing 220 are connected by the first mounting port 212 and the second mounting port 2213, avoiding the use of complex connecting pipes or additional transition structures and reducing the space occupied by the steaming machine.

[0081] In this design, one of the first mounting port 212 and the second mounting port 2213 is nested within the other, forming a tight and reliable connection. This ensures the relative position of the first housing 210 and the second housing 220 is fixed, and guarantees the sealing performance of the connection between the first housing 210 and the second housing 220. This provides a smooth and unobstructed transition channel for the airflow within the first air inlet duct 211, allowing it to efficiently enter the air inlet side of the suction component 300 from the first air inlet duct 211. This reduces airflow resistance and turbulence at the connection point, lowers energy loss, and improves airflow efficiency, thereby enhancing the suction power and performance of the steamer.

[0082] Furthermore, in some embodiments, reference is made to... Figure 1 and Figure 2 As shown, the housing assembly 200 also includes a partition 230, which is disposed within the second housing 220 and divides the second housing 220 to form a second air inlet duct 2221 and an air outlet duct 2211.

[0083] The separator 230 is provided with a connecting port 231, which connects the second air inlet duct 2221 and the air inlet side.

[0084] The separator 230 is bent within the second housing 220 and connected to the inner wall of the second housing 220 to divide the internal space of the second housing 220, thus forming a second air inlet duct 2221 and an air outlet duct 2211. This effectively avoids mutual interference between the air inlet and outlet of the steamer, making the airflow organization within the second housing 220 more orderly. Simultaneously, the separator 230 clearly delineates the second air inlet duct 2221 and the air outlet duct 2211, allowing the airflow to flow along a preset path, reducing turbulence and vortex phenomena. After entering the second air inlet duct 2221 through the second air inlet 2222, outside air can smoothly reach the air inlet side through the connecting port 231, and then be discharged from the air outlet duct 2211 via the suction component 300, improving airflow efficiency.

[0085] Specifically, an air outlet 2211 is formed between the upper first surface of the partition 230 and a portion of the second housing 220. A portion of the sidewall of the suction member 300 abuts against the first surface of the partition 230, and another portion of its sidewall abuts against the inner wall of the second housing 220. A second air inlet 2221 is formed between the lower second surface of the partition 230 and another portion of the second housing 220. A connecting port 231 is provided on the partition 230, connecting the second air inlet 2221 to the air inlet side of the suction member 300. The connecting port 231 can be a through hole on the partition 230 or a notch on one side of the partition 230, spaced apart from the second housing 220 to form the connecting port 231.

[0086] By setting the separator 230, the separator 230 is combined with the second housing 220 to form the second air inlet duct 2221 and the air outlet duct 2211. This facilitates the separate processing of the second housing 220 and the separator 230 during the production process, followed by overall assembly, thereby improving production efficiency and the controllability of product quality.

[0087] In some embodiments, refer to Figure 1 and Figure 2 As shown, the second housing 220 includes a first sub-housing 221 and a second sub-housing 222 that are connected to each other. The first sub-housing 221 is connected to the first housing 210, and the second sub-housing 222 is connected to the first sub-housing 221.

[0088] A separator 230 is disposed within the first sub-housing 221 to separate an air outlet 2211 and a portion of a second air inlet 2221 within the first sub-housing 221; an air outlet 2212 is disposed on the first sub-housing 221.

[0089] Another part of the second air inlet duct 2221 is formed inside the second sub-shell 222. The second air inlet 2222 is disposed on the second sub-shell 222 and located on the side of the control assembly 400 away from the air inlet side.

[0090] The second housing 220 is composed of a first sub-housing 221 and a second sub-housing 222 that are connected to each other. The split structure facilitates manufacturing and allows the first sub-housing 221 and the second sub-housing 222 to be processed and assembled separately, thereby improving production efficiency.

[0091] A separator 230 is disposed within the first sub-shell 221, dividing a portion of the space within the first sub-shell 221 to form an air outlet duct 2211. The second sub-shell 222 communicates with another portion of the space within the first sub-shell 221, so that the second sub-shell 222 and the other portion of the first sub-shell 221 together form a complete second air inlet duct 2221, making full use of the internal space of the first sub-shell 221. The second air inlet duct 2221 is jointly formed by a portion of the first sub-shell 221 and the second sub-shell 222, creating a continuous airflow channel distributed within the first and second sub-shells 221. Outside air enters the second air inlet duct 2221 within the second sub-shell 222 from the second air inlet 2222, then enters a portion of the second air inlet duct 2221 within the first sub-shell 221, and finally reaches the air inlet side. The entire airflow path is smooth, reducing airflow resistance and energy loss.

[0092] The second air inlet 2222 is away from the air intake side, so that the second air inlet 2222 can be relatively far away from the air outlet 2212 and the first air inlet 110, thereby ensuring that the air drawn in by the second air inlet 2222 is all cold air or room temperature gas, avoiding the second air inlet 2222 from drawing in water vapor and hot air, and ensuring short circuit protection and heat dissipation effect for the control component 400.

[0093] The first sub-shell 221 can form the head structure of the vacuum cleaner together with the first shell 210, and the second sub-shell 222 can form the handle structure of the vacuum cleaner.

[0094] In some embodiments, refer to Figure 1 and Figure 2 As shown, the minimum cross-sectional area of ​​the first air inlet duct 211 is greater than the minimum cross-sectional area of ​​the second air inlet duct 2221.

[0095] It is understood that, along the airflow path direction in the first air inlet duct 211 and the second air inlet duct 2221, the minimum cross-sectional area of ​​the first air inlet duct 211 is greater than that of the second air inlet duct 2221. This makes it easier for external airflow to enter the first air inlet duct 211 through the first air inlet 110, thereby increasing the airflow volume in the first air inlet duct 211 compared to the second air inlet duct 2221. This application does not specifically limit the location of the minimum cross-sectional areas of the first and second air inlet ducts.

[0096] When outside air enters through the first air inlet 211, it can create sufficient negative pressure at the first air inlet 110 of the panel 100, ensuring stable clothing absorption by the steam iron. Although the second air inlet 2221 has a relatively small minimum cross-sectional area and a small air volume, it can still meet the heat dissipation requirements of the control components 400.

[0097] Meanwhile, when the panel 100 is in close contact with the clothing, the first air inlet 110 is blocked, the air volume of the first air inlet duct 211 decreases, and more airflow will enter the second air inlet duct 2221. Since the cross-sectional area of ​​the second air inlet duct 2221 is smaller, the air volume of the second air inlet duct 2221 can be increased, and the wind pressure and wind speed will also increase accordingly, thereby improving the heat dissipation effect on the control component 400 and further ensuring the overheat protection of the control component 400.

[0098] Furthermore, in some embodiments, reference is made to Figure 2 As shown, the steaming machine also includes a heat sink 410, which is disposed on the control component 400 so that the control component 400 dissipates heat through the heat sink 410.

[0099] The heat sink 410 is generally made of a material with good thermal conductivity, such as a heat sink fin or heat sink column structure made of aluminum or copper. The heat sink 410 increases the heat dissipation area of ​​the control component 400, enabling it to quickly conduct away the heat generated by the control component 400.

[0100] Furthermore, in some embodiments, reference is made to Figure 1 and Figure 2 As shown, the steaming machine also includes a water tank assembly 600, which is disposed in the mounting cavity 201 and is connected to the steam generating assembly 500.

[0101] The water tank assembly 600 continuously supplies water to the steam generating assembly 500, ensuring continuous steam production. The water tank assembly 600 is housed within the mounting cavity 201, making full use of the internal space of the steamer and resulting in a more compact overall structure. Furthermore, the water tank assembly 600 is directly connected to the steam generating assembly 500 via piping, reducing the possibility of leakage and improving the reliability and stability of the equipment.

[0102] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0103] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0104] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween.

[0105] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of devices in use or operation other than those shown in the figures. Devices may have other orientations, and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
