This arrangement can further increase the air guide area of the first ventilation hole 11 and the second ventilation hole 12, thereby improving the air guide efficiency of the first ventilation hole 11 and the second ventilation hole 12. For example, when the first ventilation hole 11 and the second ventilation hole 12 are air inlet holes, the adsorption force of the ironing board 01 on the clothes can be further improved, and the adsorption force can be made more uniform, thereby further reducing the phenomenon that the clothes are blown away from the ironing board 01 due to the steam emitted from the steam hole 10 during ironing.

The ironing device further comprises a water tank 70, and the housing 04 comprises a lower part which is detachably coupled with the water tank 100 to form a handle part of the ironing device.

Referring to FIG. 9 to FIG. 15 of the drawings, according to an alternative mode of the above preferred embodiment, the ironing device comprises an ironing board 01, a heat conductive piece 08, a heating element 20, a water tank 70, a pump assembly 80 for supplying water from the water tank 70 to the heating element 20, and a housing 90.

The ironing board 01 has the at least one steam hole 10, the heat conductive piece 08 is arranged between the heating element 20 and the ironing board 01, the heat conductive piece 08 has at least one through hole 801 which is aligned with the steam hole 10.

According to this embodiment, the heat conductive piece 08 is placed between the aluminum alloy ironing board 01 and the heating element 20, so that the heat conductive piece 08 enables heat transfer to warm the aluminum alloy ironing board 01 while also serving as an insulator, ensuring complete isolation between the aluminum alloy ironing board 01 and the heating element 20, eliminating the risk of electrical conduction, and complying with safety regulations.

More specifically, the heat-conductive piece 08 is designed to transfer heat efficiently from the heating element 20 to the aluminum alloy ironing board 01. Ceramic is an excellent heat conductor, which means it ensures fast and even heating across the ironing surface. This uniform heat distribution allows for better ironing performance, reducing the likelihood of hot spots that could damage fabrics or cause uneven results.

The through hole 801 in the heat conductive piece is aligned with the steam hole 10 in the ironing board. This design ensures that steam can pass through without obstruction, enhancing the ironing experience by delivering consistent steam flow to the fabric. The alignment also prevents steam from being trapped or diverted within the structure, improving overall functionality.

One of the most critical advantages of the heat conductive piece 08 is its role as an insulator. The heat conductive piece 08 can be made of ceramic, thermally conductive silicone rubber, thermally conductive epoxy resin, or thermally conductive polymers. Theses materials have excellent electrical insulating properties, completely isolating the aluminum alloy ironing board 01 from the heating element 20. This prevents any risk of electrical conduction to the external panel, eliminating the danger of electric shock during operation and ensuring user safety.

By providing complete electrical isolation between the heating element 20 and the external aluminum alloy ironing board 01, this design ensures the device meets stringent safety regulations. The inclusion of the insulator minimizes hazards related to electrical conduction, which is essential in consumer products involving heat and electricity. This design also reduces the liability risk for manufacturers by addressing potential safety concerns in the product design phase.

In this embodiment, the heat conductive piece 08 can be embodied as a ceramic heat conductive piece. Ceramic materials are known for their high thermal stability, meaning they can withstand the high temperatures generated by the heating element 20 without degrading or warping. The inclusion of the ceramic heat conductive piece 08 helps protect both the heating element 20 and the ironing board 01 from excessive wear, thereby extending the lifespan of the iron. This durability also contributes to maintaining consistent performance over time.

The ceramic piece acts as a thermal buffer, preventing the heating element 20 from directly overheating the aluminum alloy ironing board 01. This reduces the risk of overheating, protecting both the iron and the fabrics being ironed. It provides a layer of control in heat dissipation, ensuring the ironing board reaches and maintains the desired temperature without going beyond safe limits.

With the ceramic heat conductive piece 08 ensuring both uniform heat distribution and safe operation, users benefit from a more reliable and comfortable ironing experience. The risk of electric shock is eliminated, and the even heating reduces the need for repeated passes over the fabric, improving efficiency and reducing ironing time.

The side-by-side configuration of the water tank 70 with the base housing portion 91 creates a more ergonomic handle part. The width and shape of the water tank 70 contribute to a comfortable grip. In addition, the positioning of the water tank 70 allows for increased storage capacity while maintaining a compact design, meaning the user can steam longer without needing to refill.

In this embodiment, the integration of the water tank 70 into the handle part ensures a compact, streamlined design, eliminating the need for a separate bulky handle. This keeps the handheld garment steamer light and easy to maneuver. The design of the water tank 70, coupled with the base housing portion 91, provides a sturdy, well-balanced grip. This is especially important for long steaming sessions or when steaming vertically. An upper portion of the water tank 70 is formed with a concave groove 74, so as to be ergonomically conforming to the fingers of the hand of the user which is gripped on the upper portion of the water tank 70.

More specifically, the water tank 70 comprises a tank body 71 and a seat tank portion 72 connected to a lower portion of the tank body 71 to define a water storing cavity 73. A length of the tank body 71 is larger than a length of the seat tank portion 72. The base housing portion 91 of the housing 90 is seated and supported on the seat tank portion 72 when the water tank 70 is assembled with the base housing portion 91 of the housing 11. An upper portion of the tank body 71 cooperated with the base housing portion 91 of the housing 90 for a holding hand of the user to hold thereon.

The water tank 70 and the base housing portion 91 are detachably assembled with each other by a retention unit 74. The retention unit 74 is hidden between the seat tank portion 72 of the water tank 70 and the base housing portion 91, so as to ensure the aesthetic appearance of the outer surface of the handle part 100, and prevent the unwanted touch of the user on the retention unit 74.

The locking mechanism 742 comprises a locking element 7421 defining a locking cavity 7422 with an access opening 7423, and at least one resilient element 7424 connected to the locking element 7421.

Referring to FIG. 13 of the drawings, the inserting head 7412 of the retention pin 741 can be inserted into the locking cavity 7422 through the access opening 7423, so as to be retained in the locking cavity 7422 because of the resilient force of the resilient element 7424 applied to the locking element 7421.

The locking element 7421 comprises two locking members 74211, and two resilient elements 7424 respectively connected to the two locking members 74211, the locking cavity 7422 is defined between the two locking members 74211. When the inserting head 7412 of the retention pin 741 is inserted into the locking cavity 7422, each of the two resilient elements 7424, which can be embodied as a spring, can be compressed, so that the compressed two resilient elements 7424 will securely retain the inserting head 7412 within the locking cavity 7422. A first end of each resilient element 7424 is connected to the corresponding locking member 74211, an opposite second end of each resilient element 7424 can be fixed to a wall of the base housing portion 91.

Each of the two locking members 74211 has a lower inclined guiding surface 74212 and an upper retention surface 74213, the access opening 7423 is defined between the two lower inclined guiding surfaces 74212 and is having gradually width from bottom to top, the locking cavity 7422 is defined between the two upper retention surfaces 74213. The inserting head 7412 comprises two inclined engaging surfaces 74121 each has a diamond shape.

When the water tank 70 is assembled with the base housing portion 91, the inclined engaging surfaces 74121 of the inserting head 7412 of the retention pin 741 are respectively sliding along the two lower inclined guiding surfaces 74212 of the two locking members 74211, so as to force the two locking members 74211 to move apart from each other, so that the inserting head 7412 can be moved into the locking cavity 7422, the two locking members 74211 at two opposite sides of the locking element 7421 will be compressed to allow the two upper retention surface 74213 to biasing against the inserting head 7412, so as to firmly retain the inserting head 7412 in the locking cavity 7422.

Each of the upper retention surface 74213 has a curved surface, and a lower portion of the upper retention surface 74213 is biasing against a lower surface of the inserting head 7412, so as to prevent the inserting head 7412 to escape from the locking cavity 7422.

According to this embodiment, the two resilient elements 7424 are compressed during insertion, allowing them to firmly hold the inserting head 7412 once it is inside the locking cavity 7422. This provides a reliable and secure connection between the water tank 70 and the base housing portion 91.

Each locking member 74211 has the lower inclined guiding surface 74212 that guides the insertion of the retention pin 741. The upper retention surface 74213 holds the inserting head 7412 in place. The gradual widening of the access opening 7423 from bottom to top makes insertion easier while still ensuring a snug fit once fully inserted. The diamond-shaped inclined engaging surfaces 74121 on the inserting head 7412 help guide the inserting head 7412 of the retention pin 741 into the locking cavity 7422, allowing it to smoothly slide along the inclined guiding surfaces 74212.

Once the inserting head 7412 is inside the locking cavity 7422, the upper retention surfaces 74213 press against the inserting head 7412, ensuring it remains securely locked in place. The biasing of the curved upper retention surfaces 74213 against the lower part of the inserting head 7412 prevents any accidental disengagement. The curved design of the upper retention surface 74213 provides additional security. It ensures that the inserting head 7412 is not only firmly held but also prevents any unintentional upward movement, which could cause the inserting head 7412 retention pin to escape from the locking cavity 7422.

The locking unit 74 ensures that the water tank 70 and the base housing portion 91 are tightly connected, reducing the risk of separation during operation. This is especially important for the handheld garment steamer, where stability and secure assembly are critical for safe use.

In this embodiment, each locking member 74211 comprises a protrusion 74210 which has the lower inclined guiding surface 74212, an upper curved abutting surface 74214 for abutting a lower surface 74122 of the inserting head 7412 and a biasing surface 74215 for extending into the indented groove 7413 to bias against an outer surface of the pin body 7411. By engaging with the indented groove 7413, the biasing surface 74215 prevents any displacement of the pin body 7411, further ensuring that the water tank 70 and base housing portion 91 remain securely connected during operation.

While the mechanism securely holds the water tank 70 to the base housing portion 91, it is designed to be easily detachable when needed. The resilience of the springs allows for quick and hassle-free disassembly. More specifically, when the user apply a force of the water tank 70 or the base housing portion 91, the inserting head 7412 is moved downward with respect to the base housing portion 91, so that the downward moving inserting head 7412 will force the resilient elements 7424 to be further compressed, so as to allow the two locking members 74211 to move apart, so that the inserting head 7412 can be moved out from the locking cavity 7422. Once the the inserting head 7412 is detached from the locking cavity 7422 and the access opening 7423, the restoring of the two resilient elements 7424 will restore the original positions of the two locking members 74211.

Alternatively, the inserting head 7412 also can be formed as an inserting ball which can be retained in the locking cavity 7422. The ball-shaped inserting head 7412 provides a more evenly distributed contact area within the locking cavity 7422. This ensures that the retention force applied by the locking members 74211 and resilient elements 7424 is uniformly spread, improving overall stability when the water tank 70 and base housing portion 91 are assembled. The spherical design offers less opportunity for the inserting ball to shift or become misaligned within the locking cavity 7422 which can securely hold the ball in place, reducing the risk of accidental disengagement during use.

As shown in FIG. 14, the locking unit 74 further comprises a mounting pin 743 which is protruded from the bottom bottom of the base housing portion 91, and a mounting base 744 is formed on the top wall of the seat tank portion and extending into the inner cavity of the seat tank portion 72. Accordingly, the mounting base 744 has a mounting hole 745 which can be engaged with the mounting pin 743 when the water tank 70 is assembled with the base housing portion 91. The mounting base 744 is extended into the inner cavity of the seat tank portion 72, so that the the depth of the mounting hole 745 is ensured for retaining the mounting pin 743 in position while the top wall seat tank portion 72 is allowed to have a relatively small thickness. Reducing the thickness of the top wall of the seat tank portion 72 while maintaining sufficient engagement depth for the mounting pin 743, results in a lighter handheld ironing device with a larger water storing volume of the inner cavity of the seat tank portion 72.
