Description

【Technical Field】 【0001】 The present invention relates to the technical field of ironing devices, and particularly to ironing devices. 【Background Art】 【0002】 Most of the commercially available ironing devices / handheld ironing devices only have a steam generation function. The manufacturers of ironing devices / handheld ironing devices basically focus on how to improve the heat generation efficiency and ensure the safety of the products in the research and development direction of this product. Therefore, the currently commercially available ironing device / handheld ironing device products need to be operated with both hands when ironing, and there are also problems such as easy scalding of the hands. 【0003】 In order to make the ironing device / handheld ironing device more convenient to operate, those skilled in the art have begun to add an adsorption function to the ironing device. For example, Patent Document 1, a Chinese patent with the name "A Kind of Steam Brush", discloses that "when the steam brush irons clothes, the intake device sucks air, the outside air enters from the first air outlet, a negative pressure is formed at the first air outlet to adsorb the clothes, and on the premise that there is no need to flatten the clothes by hand when ironing, and at the same time the heating element assembly heats the water from the tank assembly and ejects steam from the steam outlet, the function of ironing clothes by the steam brush is realized, and an operation method combining adsorption and ironing is adopted, so that the user can operate the handheld steam brush with one hand, and the operation is simple and easy to use." 【0004】 However, in the method of adopting this axial flow fan, since the operating voltage of the fan and the operating voltage of the heating element assembly are not in the same voltage range, an additional motherboard needs to be assembled for fan drive, so the cost is relatively high. Therefore, how to reduce the production cost of the ironing device on the premise of realizing the adsorption function has become an urgent technical problem to be solved by those skilled in the art. 【0005】 The information provided above is for background information purposes to aid in understanding this disclosure and does not constitute a determination or acknowledgment that any of the above is available as prior art to this disclosure.

Multiple nozzles 211 are provided on the surface of the heating cabin, and multiple suction holes 111 are provided on the surface of the dust collection box 11, communicating with the inside of the dust collection box 11. 【0031】 By combining Figures 1 and 2, the front case 10 and back case 20 of the ironing device can be engaged and enclosed to form a mounting cavity, and the fan 50 is located within this mounting cavity. The tuyere of the fan 50 communicates with the inside of the dust collection box 11, and when the fan 50 operates, it can draw air from inside the dust collection box 11, thereby creating negative pressure inside the dust collection box 11. 【0032】 A heating element assembly 40 is provided inside the heating cabin. As shown in Figure 3, the heating element assembly 40 includes a heating body 44 that generates steam, and the heating body 44 is provided with a main heat pipe 41 and a sub-heat pipe 42. The steam generated in the heating body 44 is ejected through the nozzle 211. 【0033】 Furthermore, as shown in Figure 6, Figure 6 is a circuit diagram of a part of the control circuit of an ironing device according to an embodiment of the present invention. 【0034】 The main heat pipe 41 and the sub-heat pipe 42 are connected in parallel, and the sub-heat pipe 42 is connected in series with the fan 50. In Figure 6, resistor R1 is the main heat pipe 41, and resistor R2 is the sub-heat pipe 42. 【0035】 The ironing device proposed in this embodiment employs a double heat pipe configuration, with both heat pipes operating simultaneously. The main heat pipe 41 generates heat to produce steam, while the sub-heat pipe 42 assists with heating and pressure distribution. A low-pressure load can be connected behind the sub-heat pipe 42. In this embodiment, there is no need to install an additional drive board to power the fan, improving heating efficiency and significantly reducing costs. Furthermore, the suction function of the fan 50 enables the combined use of suction and ironing, allowing the user to iron clothes with just one hand, which is extremely convenient. 【0036】 Specifically, as shown in Figure 3, the heating element assembly 40 further comprises a heating element upper cover 45 and a heating element lower cover 46. The heating element upper cover 45 and the heating element body 44 enclose each other to form an upper cabin (i.e., the upper cabin of the heating element body 44 shown in Figure 3), and the heating element lower cover 46 and the heating element body 44 enclose each other to form a lower cabin (i.e., the lower cabin of the heating element body 44, which is not shown in Figure 3). The upper cabin and the lower cabin are two independent cabins. 【0037】 Referring further to Figures 4 and 5, Figure 4 is a schematic diagram of the configuration of the upper flow channel of the heating element assembly 40 according to an embodiment of the present invention, and Figure 5 is a schematic diagram of the configuration of the lower flow channel of the heating element assembly 40 according to an embodiment of the present invention. 【0038】 The upper cabin and the lower cabin are connected via a connecting opening 445. 【0039】 Furthermore, as shown in Figure 4, a water inlet 451 is provided in the upper cover 45 of the heating element, and a water inlet groove 444 is formed at a position corresponding to the water inlet 451 in the upper cabin. The provision of multiple first deflectors 443 inside the upper cabin creates an upper flow path that can guide steam inside the upper cabin to the communication opening 445. 【0040】 As shown in Figure 5, a steam port 449 is provided on the side of the heating body 44 facing the outlet 211. Multiple second deflectors 447 are provided in the lower cabin, forming a lower flow path that can guide steam from the lower cabin to the steam port 449. Of these, the steam port 449 is in communication with the lower cabin. 【0041】 In a preferred embodiment, as shown in Figure 4, the bottom of the water injection groove 444 is provided with multiple protrusions (4441) for causing the water injected into the water injection groove 444 to explode into multiple small water droplets. The exploded small water droplets increase the heat-receiving surface area of ​​the water, which is advantageous for evaporation into steam and can effectively increase evaporation efficiency. 【0042】 Furthermore, in order to further improve the thermal efficiency of the heat-generating body 44, in this embodiment the upper flow path is provided as a bidirectional flow path including a first flow path and a second flow path symmetrically arranged on both sides of the water injection groove 444, so that steam in the upper cabin can flow from the first flow path or the second flow path to the communication opening 445, respectively. In this case, the steam in one direction (first flow path) flows from a in the direction of the arrow, and reaches the water injection port 451 via c. The steam in the other direction (second flow path) flows from b in the direction of the arrow, and reaches the water injection port 451 via d. 【0043】 To further ensure that the steam is sufficiently heated, the lower flow path is provided as a unidirectional flow path to increase the steam stroke length in the heating body 44. The steam flows through the unidirectional flow path to the passage outlet 4481, is discharged to the outside of the heating element assembly 40 from the steam port 449, and is ejected from the nozzle 211. Refer to Figure 5 for easier understanding. Refer to the direction of the arrows in Figure 5 for the specific flow of the steam. That is, the steam flows sequentially through efgh and is discharged from the steam port 449. 【0044】 More specifically, for example, both the main heat pipe 41 and the sub-heat pipe 42 are formed in a U-shape. 【0045】 One end of the heating body 44 (i.e., the lower right end face of the heating body 44 in Figure 4) is provided with a first mounting groove 441 for mounting the main heat pipe 41 and a second mounting groove 442 for mounting the sub-heat pipe 41. Both the first and second mounting grooves 441 and 442 are U-shaped grooves. As shown in Figure 4 or Figure 5, the sub-heat pipe 42 is positioned surrounding the outside of the main heat pipe 41, so that most of the area of ​​the entire heating body 44 is covered by the heat pipe, effectively improving the thermal efficiency of the heat pipe. Both ends of the sub-heat pipe 42 and both ends of the main heat pipe 41 protrude from one end of the heating body 44 and are used for electrical connection to an external circuit. 【0046】 Specifically, the ironing device further includes a water storage tank 30, the water inlet of a water pump 60 is connected to the water storage tank 30, and the water outlet of the water pump 60 is connected to the water inlet 451 via piping. 【0047】 As shown in Figure 3, the heating element assembly 40 further includes a thermostat 43 that controls the operating temperature of the heating body 44, and the thermostat 43 is electrically connected to the main heat pipe 41 and the sub-heat pipe 42, respectively.

Users can select materials according to their different needs and product types, so we will not explain them in detail here. 【0067】 To make it easier to understand, the ironing device works as follows: 【0068】 When a user needs to perform ironing using the ironing device, they press the trigger 12 on the front case 10 of the ironing device to trigger the microswitch 121, which starts heating the main heat pipe 41 and the sub-heat pipe 42. They also trigger the fan switch 22 (consisting of a range switch 221 and a switch cover 222) on the back case 20 to control the operation of the fan 50 and turn on the suction function. As shown in Figure 2, all of the above key switches can be installed on the key holder 14, and the specific configuration will not be described here. 【0069】 When the steam generated by the heating element 44 is uniformly ejected from the nozzle 211, the ironing process can be performed according to the item being ironed, such as clothing. When ironing, the inside of the dust collection box 11 is under negative pressure, and the item to be ironed is attracted through the suction holes 111, eliminating the need for the user to manually position the item. This allows for one-handed operation, making it very convenient. Once ironing is complete, the trigger 12 can be used to turn off the power to the entire ironing device. 【0070】 Based on the above, the present invention can effectively reduce the manufacturing cost of an ironing device while ensuring that the suction function is achieved. 【0071】 Embodiment 2: The present invention provides an ironing device comprising an ironing section consisting of an isolated heating cabin and a dust collection box 11. 【0072】 The heating cabin is provided with a heating element assembly 40, which includes a heating body 44 for generating steam.
