Description

Technical Field

[0001] This utility model relates to clothing ironing appliances, specifically a suction ironing device. Background Technology

[0002] When using a garment steamer, the released steam can blow clothes away from the work surface, hindering the steam and the work surface from effectively ironing the clothes. Using a suction fan to draw the clothes towards the work surface during ironing can overcome this drawback. However, the suction fans in existing handheld garment steamers have small openings between the fan and the suction vents, resulting in weak suction and high noise levels. Utility Model Content

[0003] This invention addresses the shortcomings of existing ironing devices that use a fan to draw clothes onto the work surface, such as weak suction and high noise, by providing a suction ironing device with strong suction and low noise.

[0004] To achieve the above objectives, the present invention provides a suction ironing device, comprising: The head housing is equipped with ventilation holes; A vaporization device, located inside the head housing, is used to vaporize water into steam; The working surface is located at the front end of the head shell. Steam holes are distributed in the middle part of the working surface, and air suction holes are distributed at the edge of the working surface. The air suction holes are distributed in a ring around the steam holes. The steam holes are used to release steam from the vaporization device, and the air suction holes are used to adsorb clothes onto the working surface by suction. The suction fan is a centrifugal fan located inside the head housing and behind the vaporization device. The suction fan includes a guide cavity, a centrifugal impeller and a motor. The guide cavity has an air inlet facing forward and an air outlet facing sideways. The air outlet is connected to the exhaust hole. When the suction fan is working, it draws air from the air inlet through the centrifugal impeller and exhausts air from the exhaust hole facing sideways. The head housing has an annular air duct located behind the working surface and radially outside the vaporization device. The annular air duct connects the suction hole and the suction fan.

[0005] This suction ironing device, when releasing steam for ironing, uses a suction fan to draw air towards the work surface, ensuring that the steam and the work surface effectively iron the clothes. Because the suction fan is located inside the head housing and behind the vaporization device, and because the head housing has an annular air duct located behind the work surface and radially outward from the vaporization device, the diameter and flow opening of the annular air duct are increased, resulting in strong suction, low noise, and uniform suction from all suction holes. Since the suction fan is located behind the vaporization device, the radial dimension of the head housing can be reduced, preventing the head profile from becoming excessively large. Furthermore, the annular air duct isolates the vaporization device from the head housing, reducing the heat radiated from the vaporization device to the head housing and preventing the head housing temperature from rising.

[0006] This suction ironing device allows for a reasonable layout of the suction fan, achieving high suction power and low noise while keeping the suction fan small.

[0007] Preferably, the exhaust vent and the exhaust hole are radially aligned. This shortens the path between the exhaust vent and the exhaust hole, ensuring smooth airflow.

[0008] Preferably, the exhaust vent is located at the front of the exhaust port and is connected to the exhaust port via an exhaust channel. This allows the exhaust to be located away from the user, preventing the exhaust air from blowing directly on the user and causing discomfort.

[0009] Preferably, the front end of the annular air duct is directly opposite the annularly distributed air intake holes. This reduces the air resistance and noise encountered by the airflow within the annular air duct during air intake.

[0010] Preferably, the vaporization device is surrounded by a cover located within the head housing, the cover serving as the inner wall of the annular air duct. The cover provides thermal insulation, preventing heat loss and reduced vaporization efficiency caused by exposed vaporization devices, and also preventing heat radiation from the vaporization device to other components, thus avoiding structural damage and reduced lifespan. The cover, acting as the inner wall of the annular air duct, facilitates smoother airflow within the duct, reducing resistance and noise. Furthermore, the airflow within the annular air duct cools the cover, significantly reducing the heat radiated from the vaporization device to the head housing.

[0011] Preferably, the head housing serves as the outer wall of the annular air duct. The structure is compact.

[0012] Preferably, a tubular component is disposed within the head housing, located outside the cover, serving as the outer wall of the annular air duct. This structure confines the annular air duct between the tubular component and the cover, further reducing the heat radiated from the vaporization device to the head housing.

[0013] Preferably, the head housing includes a front housing and a rear housing, the radial profile of the rear housing being smaller than that of the front housing, the suction fan being located in the rear housing, and a handle extending downward from the rear housing. Accordingly, when ironing while holding the handle, even if there is drifting steam, the larger profile of the front housing prolongs the distance the steam travels to the hand, preventing burns from high-temperature steam.

[0014] Preferably, the rear end of the annular air duct converges to form a converging cavity adjacent to the air inlet of the suction fan. This facilitates the convergence of airflow from the annular channel before it enters the suction fan, increasing the suction efficiency of the suction fan.

[0015] To maintain the temperature of the working surface and enhance the ironing effect by increasing contact between the working surface and the clothing, the vaporization device includes a furnace body, a furnace cover, and a vaporization chamber formed between the furnace body and the furnace cover. The furnace cover serves as the working surface, and the steam holes are directly connected to the vaporization chamber. Alternatively, the vaporization device includes a furnace body, a furnace cover, and a vaporization chamber formed between the furnace body and the furnace cover. The working surface is thermally conductively assembled with the furnace body and / or the furnace cover, and the steam holes are connected to the vaporization chamber via steam channels.

[0016] This invention increases the diameter and flow opening of the annular air duct by placing the suction fan behind the vaporization device and providing an annular air duct inside the head housing located behind the working surface and radially outward of the vaporization device. This results in strong suction, low noise, and uniform suction from all suction holes. Because the suction fan is located behind the vaporization device, the radial dimension of the head housing can be reduced, preventing the head profile from becoming excessively large. The annular air duct also isolates the vaporization device from the head housing, reducing the heat radiated from the vaporization device to the head housing and preventing the head housing temperature from rising.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages 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 protection scope of this utility model.

[0019] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion, such as a method or product that includes a series of technical features, not limited to those technical features explicitly listed, but also including other technical features that may be included in the method or product but not explicitly listed.

[0020] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0021] Figure 1-10 A steam ironing device is shown. The steam iron includes a head 10 and a handle 20. The head 10 includes a head housing 100, a vaporizing device 200, a working surface 300, and a suction fan 400.

[0022] The head housing 100 is the outer shell of the head 10. The head housing 100 is equipped with a vent 101. The head housing can be made into a one-piece structure or an assembled structure as needed.

[0023] The vaporization device 200 is located inside the head housing 100 and is used to vaporize water into steam. Therefore, a water supply pipe 201 is provided for the vaporization device, through which water is supplied to the vaporization chamber. The water is then vaporized into steam in the high-temperature vaporization chamber and discharged from the steam hole on the working surface for ironing.

[0024] The working surface 300 is located at the front end of the head housing 100 and is used to face or even contact clothing during ironing, with the ironing surface facing forward. In the illustrated structure, the working surface 300 is assembled with the head housing 100 and sealed to the front edge of the head housing 100 by a sealing element 130. Steam holes 301 are distributed in the middle of the working surface 100, and suction holes 302 are distributed at the edge of the working surface 100. The suction holes 302 are arranged in a ring around the steam holes 301. The steam holes 301 are used to release steam from the vaporization device, and the suction holes 302 are used to draw clothing onto the working surface by suction.

[0025] The suction fan 400 is a centrifugal fan, which is located inside the head housing 100 and behind the vaporization device 200. When the suction fan 400 is working, it draws air from the suction hole 302 of the working surface 300 through the centrifugal impeller 420 and exhausts air from the side-facing exhaust hole 101 of the head housing 100. The side-facing exhaust hole can prevent the exhaust air from blowing towards the user and causing discomfort.

[0026] The head housing 100 contains an annular air duct 500 located behind the working surface 300 and radially outward of the vaporization device 200. The annular air duct 500 connects the suction holes 302 and the suction fan 400. Therefore, when the suction fan is activated, it draws air from the suction holes through the annular air duct, thus adsorbing the clothing onto the working surface. Because the suction holes 302 are annularly distributed around the steam holes 301, the clothing adsorbed onto the working surface fits snugly against the edges without gaps. Steam released from the steam holes does not overflow but is forced through the clothing, achieving a better ironing effect.

[0027] This suction ironing device, when releasing steam for ironing, uses a suction fan to draw air towards the work surface, ensuring that the steam and the work surface effectively iron the clothes. Because the suction fan is located inside the head housing and behind the vaporization device, and because the head housing has an annular air duct located behind the work surface and radially outward from the vaporization device, the diameter and flow opening of the annular air duct are increased, resulting in strong suction, low noise, and uniform suction from all suction holes. Since the suction fan is located behind the vaporization device, the radial dimension of the head housing can be reduced, preventing the head profile from becoming excessively large. Furthermore, the annular air duct isolates the vaporization device from the head housing, reducing the heat radiated from the vaporization device to the head housing and preventing the head housing temperature from rising.

[0028] like Figure 4-5 As shown, the front end of the annular air duct 500 is directly opposite the annularly distributed air intake holes 302. This reduces the air resistance and noise experienced by the airflow within the annular air duct during air intake.

[0029] like Figure 4-7 , Figure 9-10As shown, the vaporization device 200 is surrounded by a cover 210 located within the head housing 100, which serves as the inner wall of the annular air duct 500. The cover provides insulation, preventing heat loss and reduced vaporization efficiency caused by exposed vaporization devices, and also preventing heat radiation from the vaporization device to other components, thus avoiding structural damage and reduced lifespan. As the inner wall of the annular air duct, the cover maintains a smooth surface, allowing for smoother airflow within the duct and reducing resistance and noise. Furthermore, the airflow within the annular air duct cools the cover, significantly reducing the heat radiated from the vaporization device to the head housing.

[0030] exist Figure 1-10 In the illustrated structure, the head housing 100 serves as the outer wall of the annular duct 500, resulting in a compact structure. In other embodiments, a tubular member located outside the cover can be constructed within the head housing, serving as the outer wall of the annular duct. This structure confines the annular duct between the tubular member and the cover, further reducing the heat radiated from the vaporization device to the head housing.

[0031] like Figure 4-5 , Figure 8-10 As shown, the suction fan 400 includes a guide cavity 450, a centrifugal impeller 420, and a motor 410. The guide cavity 450 has an air inlet 451 facing forward through an annular air duct 500 and an exhaust outlet 452 facing laterally. The exhaust outlet 452 is connected to the exhaust hole 101. This structure facilitates the rational layout of the suction fan, achieving high suction power and low noise while miniaturizing the suction fan. Moreover, the exhaust outlet 452 and the exhaust hole 101 are radially aligned, shortening the path between the exhaust outlet and the exhaust hole, ensuring smooth airflow. In other embodiments, the exhaust hole 101 is located in front of the exhaust outlet 452 and is connected to the exhaust outlet via an exhaust channel, with the exhaust hole 101 and the exhaust outlet 452 being misaligned. This allows the exhaust position to be away from the user, preventing the exhaust air from blowing directly on the user and causing discomfort.

[0032] like Figure 1-2 , Figure 4-5 As shown in Figures 9-10, the head housing 100 includes a front housing 110 and a rear housing 120, with the radial profile of the rear housing 120 being smaller than that of the front housing 110. The suction fan 400 is located in the rear housing 120, and the rear housing forms a guide cavity 450. A handle 20 extends downward from the rear housing 120. Accordingly, when ironing while holding the handle, even if there is drifting steam, the larger profile of the front housing prolongs the distance the steam travels to the hand, preventing burns from high-temperature steam. An inner frame 122 is provided inside the rear housing 120 for mounting the switch 430 of the suction fan 400. For ease of assembly, the rear end of the rear housing 120 is sealed by a tail cap 121. Furthermore...

[0033] like Figure 4-5As shown, the rear end of the annular air duct 500 converges to form a converging cavity 501 adjacent to the air inlet 451 of the suction fan. This facilitates the convergence of airflow from the annular channel before it enters the suction fan, increasing the suction efficiency of the suction fan.

[0034] like Figure 4-5 As shown in Figures 9-10, in order to maintain the temperature of the working surface and increase the ironing effect of the working surface contacting the clothing, the vaporization device 200 includes a furnace body 220, a furnace cover 230, and a vaporization chamber 240 formed between the furnace body and the furnace cover. The furnace cover 230 serves as the working surface 300, and the steam hole 301 is directly connected to the vaporization chamber 240. In other embodiments, the vaporization device includes a furnace body, a furnace cover, and a vaporization chamber formed between the furnace body and the furnace cover. The working surface is thermally conductively assembled with the furnace body and / or the furnace cover, and the steam hole is connected to the vaporization chamber via a steam channel.
